Biofuel rush is wiping out unique American grasslands

Say goodbye to the grass. The scramble for biofuels is rapidly killing off unique grasslands and pastures in the central US.

Christopher Wright and Michael Wimberly of South Dakota State University in Brookings analysed satellite images of five states in the western corn belt. They found that 530,000 hectares of grassland disappeared under blankets of maize and soya beans between 2006 and 2011. The rate was fastest in South Dakota and Iowa, with as much as 5 per cent of pasture becoming cropland each year.

The trend is being driven by rising demand for the crops, partly through incentives to use them as fuels instead of food.

The switch from meadows to crops is causing a crash in populations of ground-nesting birds. One of the US's most important breeding grounds for wildfowl, an area called the Prairie Pothole Region, is also at risk, with South Dakota's crop fields now within 100 metres of the wetlands. "Half of North American ducks breed here," says Wright.

Bill Henwood of the Temperate Grasslands Conservation Initiative in Vancouver, Canada, says the results are distressing. "Exchanging real environmental impacts for the dubious benefits of biofuels is counterproductive," he says. "Last year's record drought in the corn belt all but wiped out the crops anyway."

Cricket: Injured Jayawardene out of Bangladesh series

COLOMBO: Former Sri Lanka captain Mahela Jayawardene has been ruled out of the forthcoming home series against Bangladesh because of a finger injury.

Jayawardene, 35, who is Sri Lanka's highest run-getter in Tests, dislocated a finger in his left hand while fielding during a domestic first-class match in Colombo on Sunday.

Scans of the injury have been sent to Australia for further analysis, Sri Lanka Cricket said in a statement, adding that the batsman could be out of action for four to six weeks.

Bangladesh are due to play two Tests, three one-dayers and one Twenty20 international during their month-long tour of Sri Lanka in March.

Jayawardene, who resigned as captain after the recent Australian tour, has scored 10,806 runs in 138 Tests at an average of 49.56 with 31 centuries.

He also has 10,892 one-day runs from 391 matches with 15 hundreds, and 1,293 runs in 46 Twenty20 internationals.

All-rounder Angelo Mathews replaced Jayawardene as Test and one-day captain, while Dinesh Chandimal will lead in Twenty20 matches.

STORY HIGHLIGHTS

• NEW: Detectives are examining role of a blood-stained cricket bat, newspaper reports


• Runner Oscar Pistorius has been charged with murder in model Reeva Steenkamp's death


• Steenkamp was still alive when Pistorius carried her downstairs, an official says

Pretoria, South Africa (CNN) -- Model Reeva Steenkamp was shot four times through the bathroom door at the home of Olympian Oscar Pistorius, a South African official familiar with the case told CNN on Monday.

She was alive after she was shot and was carried downstairs by Pistorius, said the official, who was not authorized to release details to the media.

A blood-stained cricket bat has also emerged as key evidence in the case, according to the City Press newspaper of Johannesburg.

Detectives are working to determine whether the bat was used to attack Steenkamp or she used it in self-defense, the newspaper reported, citing a source with inside knowledge of the case. Detectives are also looking into the possibility that Pistorius used the bat to break down the bathroom door.

The details are the latest to emerge in the shooting death that has roiled the nation and left South Africans asking what went so terribly wrong inside the upscale Pretoria home of the man nicknamed "Blade Runner" for his lightning-fast prosthetic legs.

The official, who spoke on condition of anonymity, said there were indications the 29-year-old model intended to stay the night at the house: She had an overnight bag and her iPad.

Opinion: Pistorius case and the plague of violence against women

Authorities have released little about a possible motive in the Valentine's Day shooting, while local media have reported that Pistorius had mistaken his girlfriend for an intruder. South African authorities have stressed that the scenario did not come from them, and said there was no evidence of forced entry at the home.

Police have charged Pistorius with murder, and he will appear in court Tuesday for a bail hearing. South African prosecutors have said they intend to upgrade the charge to premeditated murder, but have not released further details.

Pistorius, 26, has rejected the murder allegation "in the strongest terms," his agent said in a statement.

Burial service

The same day Pistorius returns to court, Steenkamp will be buried in a private service in her hometown of Port Elizabeth.

Her burial Tuesday will come two days after South Africa's national broadcaster aired a pre-recorded reality TV show featuring Steenkamp discussing her exit from "Tropika Island of Treasure," on which local celebrities compete for prize money.

The decision to air the program took "much deliberation," and "this week's episode will be dedicated to Reeva's memory," said Samantha Moon, the executive producer.

The shooting has stunned South Africa, where Pistorius is a national hero as the first disabled athlete to compete in the able-bodied Olympic Games. He competed in the London Games as well as winning two gold medals in the Paralympic Games.

Headlines about the case have dominated in the days since Pistorius was arrested, though tight-lipped authorities have revealed little about what, if anything, the track star has said.

Questions swirl

Reports say Pistorius and Steenkamp became an item around November and were popular in South African social circles.

The night before the shooting, Steenkamp appeared to be looking forward to Valentine's Day.

"What do you have up your sleeve for your love tomorrow?" she asked her Twitter followers the day before. "Get excited."

Steenkamp was found in a pool of blood at Pistorius' home Thursday morning. Neighbors alerted authorities to the early morning shooting, saying they had "heard things earlier," police spokeswoman Denise Beukes has said. She did not clarify what the neighbors reported they heard.

Authorities also have not said whether Pistorius called for help.

Pictures of his walk to a police car, his head covered by a sweatshirt, have flashed repeatedly across television screens.

On Sunday, Pistorius canceled his appearances in five upcoming races.

The move is meant to help Pistorius focus on the legal proceedings and "help and support all those involved as they try to come to terms with this very difficult and distressing situation," said Peet Van Zyl of Pistorius' management company, In Site Athlete Management.

CNN's Robyn Curnow reported from South Africa; Chelsea J. Carter and Faith Karimi reported from Atlanta.

WH: Leaked immigration plan is only partial draft

(CBS News) WASHINGTON -- Over the weekend, a partial White House plan for immigration reform leaked to the press and caused an uproar.

White House officials tell CBS News that what was leaked is real -- it's a partial draft of half a bill. What we know is the administration's current thinking about what to do about the estimated 11 million illegal immigrants living in the United States right now.

The administration wants a temporary four-year visa to provide legal status -- meaning no more deportations -- that could be renewed. After eight years, they can apply for what's known as permanent legal residency, or, more commonly, a Green Card.

(At left, watch White House Chief of Staff Denis McDonough discuss the leaked immigration plan on "Face the Nation.")

There's also administration thinking on border security and an unspecified increase in border security, subject to negotiations with Congress. For workers who try to find jobs in the future and who might not have documents, the plan includes an E-Verify system to make sure undocumented workers aren't given jobs.

GOP: Leaked WH immigration plan "counterproductive"
W.H. immigration plan circulating in case Congress talks "break down," McDonough says

What's missing is a section dealing with all future legal immigration issues: high-skilled workers, seasonal farm workers and workers who work in hotels or restaurants. Without that, this plan doesn't have much of a chance.

The plan is not likely to get through Congress without the section dealing with legal immigration. That's why Republicans were so critical this weekend.

Last year, Republicans criticized the president for being missing in action and failing to draft a bill. Now that he admits he is, Republicans say he's contaminating that process; they argue that if you don't have a comprehensive bill -- one that can pass Republicans and Democrats in both the House and Senate -- this is a futile effort.

The White House says Republicans are going to be dared to vote up or down eventually, and that they better get used to that.

Obama's Speech on Guns Doesn't Stop Ill. Killing

A Chicago teenager was shot and killed Friday only hours after her sister attended President Obama's speech on the city's rampant gun violence.
Janay McFarlane, 18, was killed while walking with a friend during a visit to her dad, Herbert McFarlane, in North Chicago.

"All this gun violence going on, you never think it would be your child," he told ABC's Chicago station WLS. "This is the hardest thing for me in my life."

Herbert McFarlane told WLS that the loss of Janay is especially hard because she leaves behind a 3-month old son, who likes to wear an "I love Mommy" shirt. The shooting occurred in Lake County, a northern suburb miles from the epicenter of the gun violence on the city's South Side.

"I'm in Lake County to get away from violence and now it happened in Lake County where I moved to," he told WLS.

McFarlane and her child spent time both in Lake County and on the South Side where her mother lives.

Only hours before McFarlane was shot and killed, President Obama returned to his hometown to speak on the South Side at a Hyde Park high school. McFarlane's sister, Destini Warren, 14, sat behind the president during the speech.

More than 500 people were shot and killed here last year, and this year the situation has worsened with the most deadly January the city has seen in over a decade. The shooting death of Hadiya Pendleton, a 15-year old who performed in Washington, D.C. at events connected to the president's inauguration last month, garnered national attention.

"Too many of our children are being taken away from us," Obama said in Hyde Park, with McFarlane's sister in the audience.

"Last year there were 443 murders with a firearm on the streets of this city, and 65 of those victims were 18 and under," he said. "So that's the equivalent of a Newtown every four months." He was referring to Newtown, Conn., where 20 first graders were gunned down by Adam Lanza along with seven adults.

Only hours later in Chicago, another 18-year old was shot and killed.

"I felt like someone took a knife and stabbed me in the heart, and a piece of my heart I will never get back," Angela Blakely, Janay McFarlane's mother, told WLS.

North Chicago Police on Sunday reportedly questioned two people in connection to McFarlane's death. Her family said McFarlane was an unintended target of the shooting.

Messages left by ABC News with the North Chicago Police Department and the Lake County Coroner's Office went unreturned Monday.

Another Chicago teenager, Frances Colon, was also shot and killed Friday just hours after she had told her father that she saw President Obama's helicopter fly over her neighborhood.

Wiping out top predators messes up the climate

Wiping out top predators like lions, wolves and sharks is tragic, bad for ecosystems – and can make climate change worse. Mass extinctions of the big beasts of the jungles, grasslands and oceans could already be adding to greenhouse gases in the atmosphere.

Trisha Atwood of the University of British Columbia in Vancouver, Canada, studied the effect of removing predator fish from ponds and rivers in Canada and Costa Rica. Across a range of ecosystems, climates and predators, she found a consistent pattern: carbon dioxide emissions typically increased more than tenfold after the predators were removed.

"It looks like predators in many types of ecosystems – marine and terrestrial as well as freshwater – can play a very big role in global climate change," she told New Scientist.

The widespread and dramatic ecological impacts of the loss of top predators are well known. In the ensuing "trophic cascade", the vanished top predator's prey proliferate, which in turn puts pressure on the species that the prey eats, and so on down the food chain. In this way, changes at the top of a food chain destabilise the balance of populations right the way down.

But the geochemical impacts of trophic cascades, including any impact on emissions from ecosystems, are much less well known. Atwood's study of freshwater ecosystems showed how changes to species at the bottom of the food chain, such as photosynthesising algae, following the removal of a top predator dramatically increased the flow of CO₂ from the ecosystem to the atmosphere.

The effect will not always be to increase CO₂ emissions, however – sometimes the loss of top predators could decrease emissions, she says. "But we show that something so seemingly unrelated, like fishing all the trout from a pond or removing sharks from the ocean, could have big consequences for greenhouse-gas dynamics."

Help from kelp

Other recent studies have hinted at similar effects. Last October, Christopher Wilmers of the University of California, Santa Cruz, reported how the disappearance of sea otters is linked with increased CO₂ emissions from North American coastlines (Frontiers in Ecology and the Environment, doi.org/khz). With no otters eating them, sea urchins thrive and eat out kelp forests – often known as the "rainforests of the oceans" – resulting in major CO₂ releases.

Global climate models do not take such impacts into account yet. Atwood says they could be major, as freshwater emissions may be on a par with the influence of deforestation, which is thought responsible for around 15 per cent of human-caused CO₂ emissions.

Environmentalists will herald the findings as further evidence that it is vital to protect pristine habitats and the charismatic species at the top of their food chains. But there is a dark side. A recent study found that some island ecosystems around New Zealand store 40 per cent more carbon than others because of their top predators – invading rats that are wiping out seabird colonies. Rats, it seems, are good for the climate (Biology Letters, doi.org/bbmtw9).

Assange sees freedom in Australia senate seat

SYDNEY: WikiLeaks founder Julian Assange believes winning a seat in Australia's upper house would extricate him from his prolonged asylum inside Ecuador's London embassy, a report said Monday.

In an interview published on Australian website The Conversation, Assange outlined a scenario that would set him free to return to home.

If he takes a senate seat in the September 14 elections, "the US Department of Justice won't want to spark an international diplomatic row", The Conversation paraphrased Assange as saying.

"It will drop its grand jury espionage investigation. The Cameron government will follow suit," it added.

If Britain failed to back off "the political costs of the current standoff will be higher still", Assange said.

He added that sex crime allegations against him in Sweden were "falling apart".

A new WikiLeaks Party is to be launched soon with a 10-member national council and field candidates for the senate. Queensland-born Assange is expected to stand in Victoria state.

He has been holed up in the Ecuadoran embassy in London since June, after claiming asylum in a bid to avoid extradition to Sweden. Britain has refused to grant him safe passage out of the country.

The former computer hacker fears Sweden will allow him to be extradited to the United States to be questioned over the WikiLeaks release of thousands of US diplomatic cables.

Despite the swirl of allegations against him, Assange is a popular figure in Australia.

WikiLeaks angered the United States in 2010 by publishing hundreds of thousands of classified documents on the wars in Iraq and Afghanistan, as well as a huge cache of US diplomatic cables that embarrassed governments worldwide.

Ecuadoran President Rafael Correa called on Europe on Sunday to find a snap diplomatic solution for Assange.

"It's a diplomatic situation for which a solution must be found... as quickly as possible," Correa said shortly after declaring victory in presidential elections.

"There can't be a problem due to asylum, it's neocolonialism," he said, reiterating Quito's demands -- safe passage or questioning of Assange by a Swedish judicial official in London.

Pope delivers one of his final messages

By Hada Messia and Josh Levs, CNN

updated 7:21 PM EST, Sun February 17, 2013

Pope Benedict XVI waves as he arrives to lead the Angelus prayer at the Vatican on Sunday.

STORY HIGHLIGHTS

• It's the pope's second-to-last Angelus prayer as pontiff


• Pope Benedict XVI thanks his flock for prayers and support


• He discusses "decisive moments of our lives"


• Cardinals may meet before March 15

(CNN) -- Pope Benedict XVI led tens of thousands in a prayer for strength Sunday and thanked followers for their support during his second-to-last Angelus prayer as pontiff.

"Today we contemplate Christ in the desert, fasting, praying, and being tempted," the pope said to an unusually large crowd at St. Peter's Square in Vatican City.

"As we begin our Lenten journey, we join him and we ask him to give us strength to fight our weaknesses. Let me also thank you for the prayers and support you have shown me in these days. May God bless all of you!"

Benedict, 85, shocked millions across the world last week when he announced his intention to stand down at the end of the month, citing the frailty of old age.

The decision makes him the first pope to step down in nearly 600 years.

Referring Sunday to a Bible passage, the pope said, "During the decisive moments of our lives, and in fact at every moment, we are in front of a crossroads: Do we want to follow the I or God? The individual interest or the true good, that which really is the good?"

The crowd appeared to have about 100,000 people

He also tweeted a message to followers worldwide, calling on them to "rediscover faith" as a foundation.

Cardinals may meet before March 15 to choose the next pope if they are all in Rome, a Vatican spokesman said Saturday. The conclave will bring together the 117 cardinals of the Roman Catholic Church.

Danica Patrick makes NASCAR history

DAYTONA BEACH, Fla. Danica Patrick has made history before — as a woman and a racer, in Indianapolis and Japan.

The spotlight is nothing new. But never has it been this bright before.

Patrick won the Daytona 500 pole Sunday, becoming the first woman to secure the top spot for any race in NASCAR's premier circuit. It's by far the biggest achievement of her stock-car career.

29 Photos

Danica Patrick

"I was brought up to be the fastest driver, not the fastest girl," she said. "That was instilled in me from very young, from the beginning. Then I feel like thriving in those moments, where the pressure's on, has also been a help for me. I also feel like I've been lucky in my career to be with good teams and have good people around me. I don't think any of it would have been possible without that.

"For those reasons, I've been lucky enough to make history, be the first woman to do many things. I really just hope that I don't stop doing that. We have a lot more history to make. We are excited to do it."

Her latest stamp in the history books came with a lap at 196.434 mph around Daytona International Speedway. Patrick went out eighth in the qualifying session, then had to wait about two hours as 37 fellow drivers tried to take her spot.

Only four-time Cup champion Jeff Gordon even came close to knocking her off. Gordon was the only other driver who topped 196 mph in qualifying. He locked up the other guaranteed spot in next week's season-opening Daytona 500.

"It's great to be a part of history with Danica being on the pole," said Gordon, who joked that at least he was the fastest guy. "I think we all know how popular she is, what this will do for our sport. Congratulations to her. Proud to be on there with her."

• Danica Patrick crashes in Daytona qualifier

The rest of the field will be set in duel qualifying races Thursday.

However the lineup unfolds, all drivers will line up behind Patrick's No. 10 Chevrolet SS.

And she knows her latest achievement will mean more public relations work.

The routine is nothing new for Patrick, who was the first woman to lead laps in the Indianapolis 500. She finished third in 2009, the highest finish in that illustrious race for a woman. And she became the only woman to win an IndyCar race when she did it in Japan in 2008.

Hardly anyone witnessed that victory.

Leading the field to the green flag in NASCAR's showcase event should be must-watch television.

"That's a huge accomplishment," team owner and fellow driver Tony Stewart said. "It's not like it's been 15 or 20 years she's been trying to do this. It's her second trip to Daytona here in a Cup car. She's made history in the sport. That's stuff that we're proud of being a part of with her. It's something she should have a huge amount of pride in.

"It's never been done. There's only one person that can be the first to do anything. Doesn't matter how many do it after you do, accomplish that same goal. The first one that does always has that little bit more significance to it because you were the first."

Even before her fast lap Sunday, Patrick was the talk of Speedweeks. Not only did she open up about her budding romance with fellow Sprint Cup rookie Ricky Stenhouse Jr., but she was considered the front-runner for the pole after leading practice sessions Saturday.

And she didn't disappoint.

She kept her car at or near the bottom of the famed track and gained ground on the straightaways, showing lots of power from a Hendrick Motorsports engine.

"It's easy to come down here in your first or second year as a driver and clip the apron trying to run too tight a line or do something and scrub speed off," Stewart said. "That's something she did an awesome job. Watching her lap, she runs so smooth. ... She did her job behind the wheel, for sure."

The result surely felt good for Patrick, especially considering the former IndyCar driver has mostly struggled in three NASCAR seasons. Her best finish in 10 Cup races is 17th, and she has one top-five in 58 starts in the second-tier Nationwide Series.

She raced part-time in 2010 and 2011 while still driving a full IndyCar slate. She switched solely to stock cars last season and finished 10th in the Nationwide standings.

She made the jump to Sprint Cup this season and will battle Stenhouse for Rookie of the Year honors.

Starting out front in an unpredictable, 500-mile race doesn't guarantee any sort of result, but securing the pole will put her in the limelight for at least the rest of the week.

She also won the pole at Daytona for last year's Nationwide race.

This is considerably bigger.

The previous highest female qualifier in a Cup race was Janet Guthrie. She started ninth at Bristol and Talladega in 1977.

"It's obviously a history-making event that will last a long, long time," Guthrie said, praising Patrick's feat. "It's a different era, of course. Different times. I can't imagine what I would do with a spotter or somebody telling me how to drive. It's rather a different sport now. Back then, there was a much greater difference from the front of the field to the back."

Guthrie received a lukewarm reception from fellow drivers back then.

Patrick was much more welcomed, undoubtedly because of her background and popularity.

She's comfortable being in the spotlight, evidenced by her racing career, her television commercials and her sudden openness about her personal life.

"I think when pressure's on and when the spotlight's on, I feel like it ultimately ends up becoming some of my better moments and my better races and better results," Patrick said. "I just understand that if you put the hard work in before you go out there that you can have a little peace and a little peace of mind knowing that you've done everything you can and just let it happen."

Troubled Country Singer Shot Herself, Cops Say

Mindy McCready, the country singer who soared to the top of the charts with her debut album, "Ten Thousand Angels," but struggled with substance abuse, served time in jail and fought a lengthy battle with her mother over custody of her son has died of what appears to be a self-inflicted gunshot wound, police said. She was 37.

Deputies from the Cleburne County Sheriff's Office were dispatched to a report of gun shots fired at McCready's Heber Springs, Ark., home at around 3:30 p.m. today.

There they found McCready on the front porch. She was pronounced dead at the scene from what appeared to be a single self-inflicted gunshot wound, according to a statement from the sheriff's office.

McCready's boyfriend, David Wilson, died in January of a self-inflicted gunshot wound. McCready was ordered to enter rehab shortly after Wilson's death, and her two children, Zander, 6, and 9-month-old Zayne were taken from her. She was released after one day to undergo outpatient care.

McCready scored a number-one Billboard country hit in 1996 with "Guys Do It All the Time," but in recent years, the country crooner has received more media attention for her troubled personal life than her music.

She has been arrested multiple times on drug charges and probation violations and has been hospitalized for overdoses several times, including in 2010, when she was found unconscious at her mother's home after taking a painkiller and muscle relaxant.

Angela Weiss/Getty Images

Her mother, Gayle Inge, was appointed to be her son Zander's legal guardian in 2007 after McCready was arrested for violating probation on a drug-related charge. The boy's father is McCready's ex-boyfriend Billy McKnight.

Following a custody hearing in May 2011, McCready released a statement, saying, "We have progressed in a positive manner to reunite me and my son, Zander. I feel very optimistic this will happen in the near future."

But just six months later, in November 2011, was accused of violating a court order for failing to bring Zander back to her mother in Florida after a visit. The boy was placed in foster care while McCready and her mother worked out the custody dispute.

McCready's struggle with substance abuse was broadcast in 2010 on the third season of "Celebrity Rehab with Dr. Drew."

McCready also claimed to have carried on a decade-long affair with baseball star Roger Clemens that began was she was 15 years old and he was 28. Clemens denied that the relationship was sexual in nature.

"You know what, I don't think I'm ever going to be one of those people that has a normal, quiet existence," McCready told ABC Radio in 2010. "I've been chosen for some reason to be bigger and larger than life in every way. Negative and positive."

McCready, who was born and raised in southern Florida, moved to Nashville when she was 18 to start her music career.

Within a few months, she was starting to work with producer David Malloy, who got her tapes to RLG Records. The company signed her to a contract after seeing her in concert, giving her a record deal less than a year after her arrival in Nashville.

Her debut album, "Ten Thousand Angels," went gold within six months of its release in April 1996, and eventually went multi-platinum. Two more followed: "If I Don't Stay the Night," in 1997; and "I'm Not So Tough" in 1999.

Her most recent album, "I'm Still Here," featuring new versions of her early hits "Ten Thousand Angels" and "Guys Do It All the Time," was released in March 2010.
