In the old days, when you had to drive to a movie theater of to to a video store to get some entertainment, it was easy to see how your actions could have an impact om the environment.You were hopping into your war, driving across town and coughing out emissions（排放）and using gas all the way.
But now that we’re used to staying at home and streaming movies, we might get a little cocky. After all ,we’re just picking up our phones or maybe turning on the TV. You’re welcome.Mother Nature.
Not so fast, says a recent report from the French-based Shit Project. Watching a half-hour show would lead to 3.5 pounds of CO2 emissions. That’s like driving 3.9 miles. According to "Climate Crisis: The Unsustainable Use of Online Video," digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Stored in data centers, videos are transferred to our terminals such as computers, smart phones, etc. via networks: all these processes require electricity whose production consumes resources and usually involves CO2 emissions.
In the European Union, the Eureca project lead scientist, Rabih Bashroush, calculated that 5 billion downloads and streams of the song "Despacito" consumed as much electricity as the countries of Chad, Guinea-Bissau, Somalia, Sierra Leone and the Central African Republic used in a single year.
Streaming is only expected to increase as we become more attached to our devices. Online video use is expected to account for 80%of all internet traffic by 2022 according to CISCO. By then, about 60% of the world's population will be online.
You're probably not going to give up your streaming services, but there are things you con do to help lessen the impact of your online use.
Here are some tips:
※Disable autoplay for video on social media.
※Stream over Wi-Fi, not mobile networks.
※Watch on the smallest screen you can.
※Don’t use high-definition（高清）video on devices.

In the trailer (拖车式房屋)，Sischo was refreshing the snails ‘(锅牛）accommodations--an ongoing routine that takes days of careful work. He had found a dozen of Achatinella bulimoides--a third of the world's population of the species. Once every individual was accounted for, he cleaned the cage and packed in new leaves. The work took much trouble, but the responsibility, he said, was like “a heavy weight sitting on you.”
The trailer is very vulnerable. It’s designed to keep away would-be thieved, and to resist hurricanes. But a fire could easily destroy it, or a disease could sweep through it. Last September , a mystery pathogon（病原体）appeared to have entered the trailer on leaves fed to the snails, killing almost an entire species. As sad as the event was, there’s no good way to insure against future catastrophe. The snails can’t simply be spread among zoos or other facilities: they need special equipment, experienced handlers, and a diet of native Hawaiian plants.
Consequently, it can be hard for the snails' minders to relax, even when they are outside the trailer. “How do you switch off when your decisions mean existence or extinction?" Sischo said. While action lightens the burden, yet with animals whose natural history is largely unknown, that action can be dangerous. "If you do it wrong, the snails die.”
Snails are neither intelligent nor beloved. Sischo's friends sometimes tease him about being "the strange snail guy' ; strangers ask why he cares. It's hard to convince people, but he insists that if he can just get them in the trailer, they will understand why the Achatinella bulimoides are worth saving. "People melt," he said“When you show them that the entire population is in this chamber, it hits them."

I have recently been told that listen to loud music is gradually making people hard of hearing. I'm sure it has already been happened to my neighbor. For years she had turned a deaf ear to my requests to turn her radio down. When she gives a party she doesn’t have to invite a rest of the street. Everyone can dance in her music in his own room. Now a scientist has discovered certain electronic sounds have strangely effects on rats. He declares break down, almost paralyze(瘫) with their legs trembled. Then it is simply a matter of throwing them out by their tail. I wonder that the same thing will happen to my neighbor someday.
