In the face of the harsh environment, how should we protect our homes?

Summary. Hello: We are very happy to serve you, there are environmental problems such as marine pollution, light pollution, air pollution, and land pollution around us.

In order to protect the environment, we must start from everyone, do not use disposable chopsticks, classify garbage in a timely manner, and discourage people from destroying flowers and trees, and set up an environmental protection group to call on more people to take care of the surrounding environment. I hope I can help you, thank you, I wish you a happy life, dear.

What are the environmental problems around us? What can we do to protect the environment?

1. Air pollution.

China's sulfur dioxide emissions rank first in the world. Air pollution is currently the number one environmental problem in China.

2. Water environment pollution.

The pollution degree of China's seven major water systems is: Liaohe River, Haihe River, Huai River, Yellow River, Songhua River, Pearl River, and Yangtze River, of which 42% of the water quality exceeds the 3 categories of standards (can not be used as a drinking water source), and 36% of the urban river sections in the country are inferior to 5 categories of water quality, which has lost its use function. The water quality of large freshwater lakes (reservoirs) and urban lakes is generally poor, and more than 75% of the lakes have increased eutrophication, mainly caused by nitrogen and phosphorus pollution.

3. Garbage disposal problems.

At present, the comprehensive utilization rate of industrial solid waste in China is about 46%. Less than 10% of the country's municipal solid waste meets the requirements for harmless treatment. White contamination from plastic packaging and agricultural films has spread across the country.

What we can do to protect the environment:

1. Save water and close the faucet to prevent dripping.

2. Use detergents with caution and use soap as much as possible. Reduce water contamination by chemicals in detergents.

3. Try to use as few disposable items as possible. Use durable goods, reduce white pollution, and bring your own shopping bag or basket.

4. Do not litter waste batteries, waste plastics and other garbage; Waste sorting and putting waste into treasure and recycling.

5. Do not hunt, use rare animals and protected animals. Afforestation, take care of every inch of flowers and trees.

There are too many environmental problems around us, such as littering, spitting, and there are too many people driving, and if we want to protect the environment, we should travel with low carbon. Wait a minute.

In order to protect the environment, what we can do is: garbage sorting does not litter, do not use electrical appliances to cut off the power supply and save electricity, replace light bulbs with energy-saving lamps, take pride in saving water (turn off the faucet at any time, don't let the water run in vain), reduce exhaust emissions, and reduce the use of disposable products.

The environmental problems around us are: global warming, ozone layer depletion, acid rain, freshwater crisis, energy shortage, etc. The details are as follows.

1 Global warming: Global warming refers to the increase in global temperatures. Over the past 100 years, the global average temperature has experienced two fluctuations, cold and warm, and the overall trend can be regarded as an upward trend.

In the eighties, global temperatures rose significantly. The average global temperature in 1981 and 1990 was 0 48 higher than it was 100 years ago.

2 Ozone layer depletion: There is an ozone layer in the stratosphere, about 20 30 kilometres below the ground, in which ozone content accounts for 1/100,000 of the total gas at this altitude. Although the ozone content is very small, it has a strong function of absorbing ultraviolet rays, so it can block the damage of the sun's ultraviolet radiation to the earth's organisms and protect all life on the earth.

3 Acid rain: Acid rain is acidic precipitation with a pH of less than 5 6 caused by acidic pollutants such as sulfur dioxide (SO2) and nitrogen oxides (NOx) in the air. In areas affected by acid rain, a series of serious environmental problems have occurred, such as acidification of soils and lakes, destruction of vegetation and ecosystems, and corrosion of building materials, metal structures and cultural relics.

4 Freshwater crisis: Although the Earth's surface is covered by water2 3, 97 is undrinkable seawater, less than 3 is freshwater, and 2 of it is sequestered in polar glaciers. Of the only 1 freshwater, 25 is for industry and 70 for agriculture, with only a small fraction available for drinking and other domestic purposes.

5 Resource and energy shortage: At present, the problem of resource and energy shortage in the world has appeared in most countries and even on a global scale. The emergence of this phenomenon is mainly caused by unplanned and unreasonable large-scale exploitation by human beings.

Protecting the environment can start with small things, such as sorting garbage, picking up mineral water bottles and cigarette butts on the road, sweeping the streets, pruning tree branches, and other details can contribute to the environment.
