First of all, it is necessary to publicize a lot to raise people's awareness and strengthen environmental awareness.
Secondly, we should recycle waste and reduce the felling of forest trees. We should also strengthen the control of white pollution and use less plastic products.
Finally, we should improve the cleanliness and make the city cleaner.
For the sake of the earth's tomorrow, we must work hard and protect the environment from now on. Here we put forward the following suggestions:
Carrying out garbage sorting and bagging can not only reduce the workload of sanitation workers, but also make better use of waste, reduce pollution and save resources.
Use less plastic bags and try to use bamboo baskets when buying food.
Try to use pens with replaceable refills to reduce the waste and rubbish of ballpoint pen shells.
Try not to use disposable lunch boxes when eating out.
Sowing green means sowing the hope of excess garbage and environmental problems. Recovery and comprehensive utilization of toilet garbage (2) popular science.
Think of drinking pure water
Nowadays, drinking water is becoming a trend. Although the media has introduced the disadvantages of drinking water more than once, the family of "drinking water" is still expanding day by day.
Drinking water not only refers to pure water, but also includes mineral water, distilled water and even space water. However, drinking tap water from our childhood has become relatively "non-drinking water". It is not ruled out that drinking water is popular at present, and speculation has played a certain role, but it reflects that the current water pollution has reached an unbearable level.
It is reported: "It is reported that in 979, a survey of 798 cities and towns in China showed that the daily sewage discharge in China was 2.58 million tons, including 8 19 for industrial wastewater and 0/99.1989 for domestic sewage. Through the investigation of 854 towns in China, the daily sewage discharge reaches 36.53 billion tons, of which 550 million tons are industrial wastewater.
In addition, there is an indisputable fact in Shanghai. Huangpu River, the mother river of Shanghai, was a clear river full of fish and shrimp before the mid-1950s (1958). 1962 water quality began to be polluted, and 1963 began to have 22 dark and smelly periods, 65438+.
The harm of water pollution is self-evident. Water pollution and water quality deterioration have brought serious harm to human health, human life and production.
Water is an important substance for human survival. A person who leads an honest and clean life can bring people lush flowers, birds and flowers, tranquility and comfort, picturesque scenery and beautiful environment, and bring people tranquility, joy and peace. But today's polluted water has brought people pain, terror and disaster. In order to make life better, let beautiful mountains and rivers stay in the world forever, and let clear water flow continuously, people have become more and more aware of the importance of preventing water pollution.
Sowing green means sowing hope for excess garbage and environmental problems. From drinking pure water, think of recycling and comprehensive utilization of garbage. Recycling and comprehensive utilization of garbage is a science in the bathroom.
China is a country that is seriously short of water. The total amount of fresh water resources in China is 2.8 trillion cubic meters, accounting for 6% of the global water resources, ranking fourth in the world, second only to Brazil, Russia and Canada, but the average per capita is only 2,200 cubic meters, which is only 1/4 of the world average and 1/5 of the United States, ranking first in the world.
The Ministry of Construction has predicted that the peak of water shortage in China will be in 2030, when the population of China will reach about 65.438+0.6 billion, and the per capita water resources will be 654.38+0.760 cubic meters, ranking among the countries with moderate water shortage determined by relevant United Nations organizations.
According to statistics, by the end of the second half of 2005, the total urban water shortage in China reached 6 billion cubic meters, and more than 400 cities in China had water shortage problems to varying degrees, among which 136 was seriously short of water. At the same time, 50% of urban groundwater is polluted to varying degrees, and some cities have already experienced water crisis.
With the market-oriented development of urban public utilities in China, the water market in China has become a hot investment spot at home and abroad, and the water market in China will maintain an annual growth rate of 65,438+05% for a long time.
What is "white pollution"?
"White pollution" mainly refers to the two negative effects of plastic waste, "visual pollution" and "potential harm" to the environment.
"Visual pollution" refers to the damage of plastic waste scattered in the environment to the city appearance and landscape, such as disposable foamed plastic tableware scattered in the natural environment, ultra-thin plastic bags scattered on both sides of railways, rivers and lakes, flying all over the sky or hanging on branches, which brings bad stimulation to people's vision.
"Potential harm" refers to the long-term deep-seated environmental problems caused by the difficulty of degradation of plastic waste after it enters the natural environment, which mainly includes the following aspects.
1. Plastic film waste remains in the soil in a large area and accumulates for a long time, causing soil hardening, affecting crops' absorption of nutrients and water, and leading to crop yield reduction.
2. Plastic waste discarded on land or in water is eaten by animals as food, resulting in the death of animals.
3. The plastic garbage entering the domestic garbage is light in weight, large in volume and difficult to handle. If it is buried, it will occupy a lot of land and be difficult to degrade for a long time.
Nairobi, 22 May (Reporter Wang) The latest research report released by the United Nations Environment Programme here on 22 May pointed out that the global environmental situation has been deteriorating over the past 30 years. If the international community does not take effective measures quickly, the future development and survival of mankind will face great threats. This report, called Global Environment Outlook, was organized by the United Nations Environment Programme 1000 and written by more than one scientist. The report evaluates the global environmental situation since 1972 and predicts the environmental development trend in the next 30 years. The report points out that the uncontrolled exploitation and destruction of natural resources by human beings is an important cause of global environmental deterioration, including the emission of greenhouse gases and pollutants, deforestation, over-exploitation of wetlands and beaches and unplanned urban construction.
The report pointed out that global warming has led to frequent natural disasters such as floods and droughts. In the 1980s, the global average population affected by disasters was 65.438+0.47 billion, but in the 1990s, this figure rose to 265.438+0.654.38+0 billion. At the same time, human fresh water supply is also facing great pressure. At present, half of the rivers in the world have been greatly reduced or seriously polluted, and 80 countries in the world, or 40% of the world's population, are seriously short of water. The report predicts that if this trend is not contained, more than 55% of the world's population will face water shortage within 30 years.
The report said that the deterioration of the natural environment also seriously threatened the wild species on the earth. At present, 12% of birds and a quarter of mammals in the world are on the verge of extinction, and overfishing leads to the depletion of one third of fish resources. The report also lists other serious environmental problems, such as land desertification, species variation and the increase of ozone hole in the atmosphere.
The report emphasizes that mankind is now faced with an important choice-whether to concentrate on economic development or take the road of sustainable development. The population of developed countries accounts for only one-fifth of the world's population, but personal consumption accounts for 90% of the world. This way of excessive consumption must be changed.
Tepfer, Executive Director of the United Nations Environment Programme, pointed out that without environmental protection, the world could not achieve sustainable development. He called on the international community to take concrete actions quickly to protect the environment on which human beings depend for the benefit of themselves and future generations.

Dizzy ~ ~ The more detailed you want to write, the better. Let me offer you a few topics. Wildlife protection, land desertification, battery problems, noise (water, heavy metals, arsenic ... waste gas) pollution sources, hazards and treatment. Most importantly, the most important environmental education in China is quite backward, conscious and conceptual. They lack awareness of environmental crisis. They don't want to know about it, because living in such a GCZYGJ is very stressful, so ... it is more difficult to promote sustainable development. As for environmental management, environmental impact assessment is not a major, so there is no need to write it.

Environmental protection is the biggest problem that human beings face in modern life. To solve this problem, we must start from the foundation.
First of all, it is necessary to publicize a lot to raise people's awareness and strengthen environmental awareness.
