高三阅读理解In the old days when you had to drive

In the old days, when you had to drive to a movie theater or go to a video store to get some entertainment, it was easy to see how your actions could have an impact on the environment. You were hopping into your car, 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 Shift 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 can 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.
