Dear friends:

Now the sky lacks the blue of the past, the river is no longer clear, and the air is often filled with thick smog. White pollution and tail gas lead to global warming, and rising sea level makes the earth, the home on which humans and animals depend, riddled with holes.

In recent years, the first carbon environmental protection has become a life style that people yearn for. In order to restore the original color of the sky, make the air fresh again, and give small fish and shrimp a place to live, we have issued an initiative:

1. "Don't let the last drop of water turn into human tears". We should control and recycle water, water the flowers with rice washing water, and flush the toilet with face washing water. Don't turn on the faucet every time you use it, and then twist it after use.

2. Every saving 1 kWh. Don't turn on the light when the indoor light is strong during the day. Don't open the doors and windows when you turn on the air conditioner. It is best to keep the air conditioning temperature at around 26 degrees.

There is a lot of white pollution now, and it will take more than 200 years to degrade these wastes. Try to reduce the use of disposable items, such as disposable chopsticks, three boxes at a time, to reduce white pollution.

4. Low-carbon life, drive less, pick up and drop off children to and from work, try to ride an electric car or bicycle by bus on foot, those who can't walk don't ride a bike, and those who can ride a bike don't drive.
