A composition about protecting the earth's environment or protecting forests

people always think that the sea, land and air on the earth are endless, so they never worry about sending tens of millions of tons of waste gas into the sky and dumping hundreds of millions of tons of garbage into the ocean. Everyone thinks that the world is so big, what is this waste? We are wrong. In fact, although the earth is big, creatures can only live in the range of 8 kilometers above sea level to 11 kilometers under the sea, and 95% of the creatures can only live in the range of about 3 kilometers in the middle. People have wantonly polluted this limited living environment from three aspects.

marine pollution: mainly crude oil leaked from oil tankers and oil wells, pesticides and fertilizers used in farmland, sewage discharged from factories, and acidic solutions from mines; They pollute most marine lakes. As a result, not only marine organisms are harmed, but also birds and humans may be poisoned by eating these organisms.

Land pollution: Garbage cleaning has become an important problem in major cities. Many of the tens of millions of tons of garbage every day cannot be incinerated or decomposed, such as plastic, rubber, glass, aluminum and other wastes. They have become the number one enemy of urban health.

air pollution: this is the most direct and serious, mainly from carbon monoxide and hydrogen sulfide released by factories, automobiles, power plants, etc. Every day, people get sick of respiratory organs or visual organs due to contact with these dirty air. If we still ignore the experts' warnings, we will definitely fall to the point where there is no half an inch of pure land to live in in the future.

environmental pollution refers to the phenomenon that human beings directly or indirectly discharge substances or energy that exceed their self-purification ability to the environment, thus reducing the quality of the environment and adversely affecting human survival and development, ecosystems and property. Specifically, it includes: water pollution, air pollution, noise pollution and radioactive pollution. Water pollution refers to the phenomenon that the chemical, physical, biological or radioactive pollution characteristics of water body are changed due to the intervention of certain substances, thus affecting the effective use of water, endangering human health or destroying the ecological environment, resulting in the deterioration of water quality. Air pollution refers to the phenomenon that the concentration of pollutants in the air reaches a harmful level, which destroys the ecological system and the conditions for the normal survival and development of human beings and causes harm to people and creatures. Noise pollution refers to the phenomenon that the generated environmental noise exceeds the national environmental noise emission standard and interferes with the normal work, study and life of others. Radioactive pollution refers to the appearance of radioactive substances or rays exceeding the national standards on the surface or inside of materials, people, places and environmental media due to human activities. For example, exceeding the standards for the discharge of pollutants set by the state and local governments, discharging pollutants in excess of categories, quantities and concentrations; Loading and transporting oil or toxic goods without taking measures to prevent overflow and leakage, causing the goods to fall into the water and causing water pollution; Illegal discharge of toxic and harmful substances into the atmosphere, causing air pollution accidents, and so on.

with the development of science and technology and the improvement of people's living standards, environmental pollution is also increasing, especially in developing countries. The problem of environmental pollution is becoming one of the same topics in every country in the world.

People's unpredictable negative impact on highly developed industries and unfavorable prevention have led to three global crises: resource shortage, environmental pollution and ecological destruction. People constantly discharge pollutants into the environment. However, due to the diffusion, dilution, redox and biodegradation of the atmosphere, water and soil, etc. The concentration and toxicity of pollutants will naturally decrease, which is called environmental self-purification. If the discharged substances exceed the self-purification capacity of the environment, the environmental quality will change adversely, endangering human health and survival, and this will lead to environmental pollution.

Environmental pollution will reduce biological production and aggravate environmental damage.

Environmental pollution sources mainly include the following aspects:

1) Waste smoke, waste gas, waste water, waste residue and noise discharged from factories;

2) Waste smoke, waste gas, noise, stolen water and garbage discharged from people's lives;

3) Exhaust gas and noise emitted by vehicles (all fuel vehicles, ships, airplanes, etc.);

4) The water from the farmland irrigated with chemical substances such as fertilizers, pesticides and herbicides.

5

) Mine wastewater and waste residue.

The harm of water pollution is self-evident. Water pollution and water quality deterioration have brought serious environmental protection to human health, human life and production, which is the biggest problem faced by human beings in modern life. To solve this problem, we must start from the foundation.

First, we should publicize a lot, raise people's awareness and understanding, and strengthen environmental awareness.

Secondly, we should recycle waste. Reduce the felling of forest trees. We should also strengthen the treatment of white pollution and use less plastic products.

Finally, we should improve the cleanliness and make the city look cleaner.

For the sake of the earth's tomorrow, we must work hard from now on and protect the environment well. Here we put forward the following suggestions:

Carry out garbage sorting and bagging. This will not only reduce the workload of sanitation workers, but also better utilize waste. Save resources.

When buying food, use less plastic bags and try to use bamboo baskets.

Try to use pens with replaceable cores. Reduce the waste and garbage of ballpoint pens.

Try not to use disposable lunch boxes when going out to eat.

Sowing green means sowing the hope of excess garbage and environmental problems. Recycling and comprehensive utilization of garbage (below) Science in the bathroom

Thinking of drinking pure water

Nowadays, drinking water is becoming a trend. Although the media has introduced the disadvantages of drinking water more than once, However, the drinking aquarium 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, etc. However, drinking tap water that we have grown up has become relatively non-drinking water. We do not rule 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 a level that is difficult to eat.
