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.

The new garbage sorting regulation has taken effect in Shanghai starting July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to clarify the new rules.
The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, hazardous (有害的) waste, household food waste and residual (剩余的) waste.
Hazardous waste, as the name suggests, includes assorted poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides.
Household food waste, which is translated to “wet trash” in Chinese，refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers.
Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste.
The definition of residual waste is a little confusing. Anything that is not listed above belongs in this category.
As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own ways to sort trash.
“We should do this from a pig’s angle,” commented one netizen. “Those edible (可食用的) for pigs are household food waste. Those even pigs don’t want to eat are residual waste. If a pig consumes something and dies of it, then something must be hazardous waste. Those which can be sold and the money we gain can be used to purchase pigs are recyclable waste.” The new regulation has gone into effect on July 1. Those who do not sort their trash properly will be fined RMB200.
