2 . More than half of the birds in Washington are at risk of extinction because of climate change. That's according to a new national report from the Audubon Society, which gives detailed analysis of climate effects on about 600 species of North American birds.

It's based on more than 140 million observations of birds across the US, Mexico and Canada. Audubon scientists looked at the likely effects of sea-level rise, urbanization, drought, extreme spring heat, increased fires, heavy rain and other factors.

But it doesn't just spell out a doomsday scenario (世界末日).Instead, it offers a range of effects and warming, depending on how much carbon humans add to the atmosphere.

"It is truly an existential threat (威胁), not only to birds but to people,” said Doug Santoni, board chair of Audubon Washington, who looked into the report as soon as it came out.

Santoni says he was struck to see the vulnerability (脆弱)of a common “ backyard bird" , the dark-eyed junco. It's one that many first-time birders become familiar with as they learn how to identify species based on their markings and other traits. Currently in Washington, you can count on juncos to show up at your feeder, year round. Extreme spring heat, increased fires and heavy rain are the kinds of changes that will force birds like these north, or kill them off if they fail to adapt.

Trina Bayard, director of bird conservation at Audubon’s Washington chapter, says, "It's certainly a very serious warning report," but adds that there’s still hope. “If we can stabilize current temperatures and decrease our emissions (排放), we can really reduce the effects to these birds …that's very motivating. ”

3 . Coca-Cola, which reportedly produced more than 3 million tons of plastic packaging in 2017, announced Thursday it wants to “help fix the world’s plastic waste problem one community (社区) at a time.”

The soda giant is doing so by providing $ 5.4 million for recycling programs in cities like Atlanta, Boston, Denver and Houston. In these cities, partners, like The Green Blue Institute and The Recycling Partnership, which receive the money, will work together to improve recycling rates.

“We focus on areas where we have the ability to make the biggest influence on communities through the funding and expert skills of Coca-Cola employees,” Carlos Pagoagoa, Coca-Cola’s group director of community partnerships, said in a statement. “In each city, local partners will work together to identify barriers to recycling on a local level and test a range of solutions,” he added. “We hope the learnings from these ‘model markets’ can offer solutions to other cities facing similar challenges.”

As part of the effort, The Recycling Partnership and the city of Atlanta, where the cola company’s headquarters are based, will send street teams out to open recycling carts and leave citizens cards informing them what they can and can’t recycle, and let them know how their efforts work.

“Two of the most urgent problems with recycling in the U. S. today are lack of access, followed by pollution in recycling,” Keefe Harrison, CEO of The Recycling Partnership, said in a statement. “We know from the success of Atlanta in 2017 that the citizens want to recycle, and that communicating with them in the street works.”

Last year, Coca-Cola announced its task to collect and reuse a bottle or can for each one it sells, and increase the amount of its products out of recycled materials to 50% by 2030. The brand also aims to make all its packaging fully recyclable by 2025.
