I want to take an action to put my family on the path to zero waste. First, I'll make sure the water in my house won't be left running when no one is using them and the lights in my room will be turned off when I left. Of course, I'll convince my parents to packing the goods in cloth bags instead plastic bags. Beside, I plan to do at least one environmental volunteer project with my family a week. For example, we can spare a few hour on Saturdays to serve at a restaurant but remind diners not to waste food. I'm surely we will be amazed at what much satisfaction we get from our work.

3 . On November 7, Lewis Pugh completed a one-kilometer swim in the freezing waters of King Edward Cove, off South Georgia in Antarctica. He was wearing only his swimming glasses, cap and Speedo !

Pugh is an advocate for our oceans and seas, working to protect these ecosystems with their large diversity of marine life. When asked why he doesn't wear a wetsuit(防寒泳衣), Pugh says, "I ask world leaders to do everything they can to protect our oceans. Sometimes the steps they need to take are difficult and unpopular. If I'm asking them to be courageous, I must also be. Swimming in a wetsuit would not send the right message."

It took Pugh about 19 minutes to complete the one-kilometer swim in Antarctica where the water averaged about 1.6 degrees Celsius. He says that his body can only tolerate about 20 minutes in the freezing waters before it starts shutting down. As he swims, his body temperature steadily drops, which in turn causes his muscle control to drop, slowing him down. When he is done with his swim, his support team rushes him to a hot shower and it takes almost an hour for his body temperature to return to normal.

Doctors and Pugh caution that one must receive months of training to swim in such cold waters. Even expert swimmers who are unused to freezing water can drown within minutes because of the physical shock experienced by the body. Pugh says he trained for six months before this swim.

This is not the first time that Pugh has swum in dangerous conditions. In 2007, he swam one kilometer in the North Pole to draw attention to the melting Arctic ice due to climate change. In 2015, he swam in the Bay of Whales in Antarctica's Ross Sea as part of his successful campaign to help set up a marine reserve there.

4 . Rachel Carson was concerned about what was happenig to the environment. So   in her book Silent Spring, she warned that some chemicals were poisoning the air, the water, the earth, and all its creatures. She imagined a time when spring would not bring the rebirth of flowers, trees, and the songs of birds. The book became a bestseller, and Ms. Carson was in great demand as a speaker. People lisened to her because what she said made sense, and because she was a scientist who knew her facts.

Rachel Carson was primarily interested in the world of sea and shore, so she       became a marine biologst for the government. She studied and recorded facts about the sea' s plant and animal life, their special characteristics, and the nature of their environments. In 1951, she wrote The Sea Around Us, which brought her honors, fame, and respect around the world.

Ms. Carson then devoted herself full-time to research and writing. One thing     much on her mind was the effect of modern technology on the natural environment. One day, a distressed friend wrote her to say that a plane spraying(喷洒) DDT had flown over her yard, and the next day several birds lay dead. Carson decided to act.

For four years she studied the use of pesticides(杀虫剂) in the United States, and then she wrote Silent Spring.

In her book Ms. Carson said that these pesticides would harm much more than     insects. She explained that these poisons would pollute the environment. “Even if their effects are not immediately observable, they remain for years in the water and the soil, and they become part of the food eaten by animals and humans.

Besides, after a time, insects develop immunity to pesticides,” she said.

Recent studies have shown that pesticides can affect human brainwave activity   and cause loss of memory and inability to concentrate. We should still remember Rachel Carson’s words, “I think we are challenged as we have never been challenged before to prove our mastery, not of nature, but of ourselves.”

5 . 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.
