National Wildlife Federation (NWF)
Founded officially in 1937, the National Wildlife Federation tries to protect wildlife at all costs.

The money goes to buy endangered wilderness land to protect it from companies that would destroy it. So far, Ecology Fund, com has bought land in many areas.

Imagine someone who has spent the majority of their life sitting with a sign on the side of the road and that very person giving someone their last 20 dollars. That's exactly what Marine Corps veteran (退伍军人) Johnny Bobbitt, 34, did in October in Philadelphia.
Bobbitt served in the U.S. Marine Corps and worked as a paramedic (医务辅助人员) in Vance County, N. C. before he became homeless. Nobody knew how he got to where he was because he was discreet about that.
One night in October, Bobbitt was sitting roadside with a sign in Philadelphia as usual, when Kate McClure of Florence Township, N. J. was driving home down Interstate 95 and ran out of gas. Scared and nervous, she got out of the car to head to the nearest gas station. As McClure was heading to the nearest gas station, she ran into Bobbitt and he told her to get back in the vehicle and lock the door. Minutes later, he appeared with a red gas can. He'd used his last $20 to buy her gas.
After that unexpected meeting, McClure and her boyfriend, Mark D'Amico, who both live in New Jersey, visited Bobbitt several times to deliver gift cards, cash, snacks and toiletries. They then decided to create a fund raising page so he wouldn't have to spend the holidays sleeping on the street.
McClure started the GoFundMe page on November 10. With the page, the couple hoped to raise $10,000, enough money for his rent, a reliable vehicle and up to six months' expenses. Bobbitt's story ran in a local paper. By November 15，more than 10,000 local people had made donations through the GoFundMe page and more than $300,000 had been raised.
On Thanksgiving, Bobbitt was resting in a hotel, his feet up on the bed, drawing up a grand plan for his new life, thanks to several thousand dollars raised to repay him for a good deed.
City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO2 from the air than forest trees.
As we all know, the earth would be freezing or burning hot without CO2. However, CO2 is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe.
Studies had shown forests readily absorb CO2, but there hadn't been much data on whether city trees grow, die and absorb CO2 at the same rate as forest trees do. So some researchers decided to find out.
To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree's diameter increases as it grows, just as a person's waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years' tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2.
City trees grew faster because they had less competition for light from their neighbors. In a forest，trees tend to grow close together，shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.
Do you know that junk food isn't healthy? Of course you do! Do you eat it anyway? Of course you do! But a new study shows teaching adolescents about the ways food companies fool them into thinking junk food is cool can encourage kids to fight back—by eating healthier.
The pull of junk food can be super-strong. It's designed to tasty; which makes eating well one of the great health challenges of our time. Everyone from doctors to the government has been trying to handle it. Yet we keep eating junk food.
Professor Christopher Bryan says, "Food companies want you to want junk food." They spend millions of dollars coming up with new ways to^ promote junk food consumption. They hire scientists to make new junk food almost irresistible. They might do this, for example, by adding more sugar. Rats fed junk food for six weeks will even walk across a floor that gives them electric shocks just to get more of such food.
Food ads often make unhealthy junk food seem healthy by featuring professional athletes, fit-looking pop stars and smiling, active teens. "We thought when the students learned this, it would matter to them," Bryan says. He worked with 8th graders at a Texas school. Half of them got a lesson Bryan created. It focused on the ways junk food is advertised, or marketed. A second group received lessons that focused on health. These lessons informed students junk food is had, and that foods like apples or carrots are a better choice. The students learned a bad diet can lead to major weight gain, and that being overweight puts people at risk for serious diseases. They also learned how eating well now can keep you healthy when you're older.
After the lessons, the kids in both groups were asked how they felt about junk food. Most didn't have positive feelings about these unhealthy foods.
HungerIs Good for You

Kiwis are endangered little birds native to New Zealand. It (believe) that these small birds exist as a result of New Zealand's isolation (隔离)from the other parts of the world, forcing animals there (adapt)and evolve (进化)so as to be able to survive and reproduce. The evolution is what has led to the present(appear) of the kiwi bird.
Kiwis are a national symbol of New Zealand, with the name kiwi (be) associated with many things in New Zealand including their famous rugby national team.
Kiwis have excellent memories and can remember something that (happen) as long as five years back. Even though they have feathers, their feathers look and feel (much) like hair rather than feathers.
This enables them to be able to hide in a bush and go (complete) unnoticed by their natural enemies.
Unlike most birds, the kiwi bird has a great sense of smell enables them to sniff out prey (猎物)hidden in bushes and underground.
The smallest kiwi bird has height of 45 centimeters and wight of 2 kilograms while the largest kiwi can grow 50 centimeters tall and can weigh 3.5 kilograms.

Yesterday morning I was on my way to work. Suddenly I stopped by a woman on the sidewalk. She asked me if I knew how to get to CASS, that is a local shelter for the homeless. I could tell she was extreme upset, so I told her I'd look it up for her on my smartphones. While waiting, she told the she was losing and didn't have money for the bus. I took out of a 20-dollar bill from my purse but handed it to her. Then I accompany her to the nearest bus stop. See the happy smile on her face brightened up my day, either.
