Name: Maas Valley Incident.
Place of occurrence: Maas Valley Industrial Zone, Belgium.
Cause: The industrial area is located in a narrow basin, and the temperature reversal occurred from December 1 to 5, and the harmful gases emitted by the factory accumulated near the surface, and it is speculated that the concentration of sulfur dioxide in the atmosphere at the time of the incident was 25-100mg m3, and some people believe that there was fluoride pollution. It is generally believed to be the comprehensive effect of several harmful gases and dusts on the human body.
Main consequences: Someone became ill after three days, and the symptoms were chest pain, cough, difficulty breathing, etc. More than 60 people died in a week. Patients with heart disease and lung disease have the highest mortality rate. At the same time, many domestic animals died.
Name: London Smog Incident.
Location: London, England.
Causes: From the 5th to the 8th, almost the entire territory of the United Kingdom was covered with smoke, and the temperature increased inversely, and the inversion layer was at a low altitude of 40-150m, resulting in the continuous accumulation of smoke from coal burning. The concentration of dust particles is up to 10 times that of usual; Sulphur dioxide is up to 6 times the usual amount.
The ferric oxide in the smoke promotes the oxidation of sulfur dioxide to produce sulfuric acid foam, which condenses on the smoke or condensation source to form an acid mist.
Main consequences: About 4,000 more deaths in four days than in a normal cycle. Deaths are highest among those over the age of 45, about three times as many as usual; For those under 1 year old, it is about twice as high as usual.
The deaths of people with bronchitis, coronary heart disease, tuberculosis and heart weakness in the first week of the event were times the number of deaths of the same kind in the first week of the event, respectively. Mortality rates from pneumonia, lung cancer, influenza and other respiratory diseases have increased exponentially.
Name: Painful Disease Event.
Place of occurrence: Jintong River basin, Toyama Prefecture, Japan.
Causes: Cadmium-containing wastewater discharged from zinc and lead smelting plants polluted the water body of the Shentong River, and residents on both sides of the river used river water to irrigate farmland, making rice contain cadmium, and residents were poisoned by eating cadmium-containing rice and drinking cadmium-containing water.
Main consequences: The number of patients before 1963 is unknown. Between 1963 and March 1979, there were 130 patients (more than 90% of whom were over 65 years of age and only 3 men), of whom 81 died.

Shocking environmental pollution can be seen everywhere: dark skies, polluted air, cross-flowing sewage, and ...... garbage sieges, even in the ice and snow of the Antarctic penguins, DDT and other pesticide residues have been found, Mount Everest is everywhere? The blue sky and clear water have become a childhood memory and unattainable dream for many people.
The Antarctic ozone hole is caused by excessive use of freon in the past and its emission into the air, which will irradiate a large amount of ultraviolet rays on the earth, increase the incidence of cancer, and increase the temperature of the earth; Red tide occurs in many waters because domestic and industrial wastewater enters the waters, which are rich in nitrogen and phosphorus, which causes eutrophication, which will lead to the death of fish and shrimp, and will also damage people's health through bioaccumulation; The destruction of virgin forests in the United States is man-made, and many trees have been cut down. As a result, many animals have been displaced, and some species have even perished.
Lop Nur, the Disappearing Fairy Lake", that is, Lop Nur was originally a very beautiful lake, but now it has disappeared and become a desert. This is a tragedy of man-made destruction of the ecological environment. With a strong voice, this reportage warns the people of the world to establish the awareness of environmental protection among the whole people and do a good job in ecological protection.
Cutting down trees. Digging river sand.
The cause of animal killing and environmental pollution is mainly caused by human factors. Usually people in production, life emissions of a large number of "three.
"Waste" and sudden accidents in some industrial and living facilities, as well as untreated waste in hospitals, can cause environmental pollution, and in serious cases, it can cause harm. In wartime, due to the massive use of various ** to kill residents and damage residential areas, it can cause environmental pollution and destruction.
For example, air pollution in cities causes air pollution, and people's morbidity increases. Water pollution deteriorates the quality of the water environment, and the quality of drinking water sources generally declines, threatening people's health, causing premature birth or malformation of the fetus. Serious pollution incidents not only cause health problems, but also social problems. With the intensification of pollution and the improvement of people's environmental awareness, the disputes and conflicts among people caused by pollution are increasing year by year.

Examples of environmental damage include exhaust emissions, sewage discharge, discarding of used batteries, littering, trampling on lawns, and deforestation. Due to the intensification of human development and utilization of the environment, the original ecological environment has been changed, and once the environment is seriously damaged, it is difficult to restore the original state.
How individuals can do a good job of environmental protection.
Minimize the use of white plastic and disposable items on weekdays, and use cloth bags or biodegradable plastic bags when shopping.
Choose low-carbon travel and drive as little as possible, because car exhaust is a harmful substance, which can reduce the harm to the environment caused by car exhaust emissions.
Do a good job of garbage classification, do not litter, garbage classification can promote the effective recycling of resources and improve the environment, reduce environmental pollution.

There are: littering, felling trees, exhaust fumes from cars...
There are various classifications of environmental pollution: >>>More
Examples of people destroying natural resources at will:
1. Acid rain: Acid rain is acidic precipitation with a pH value less than that 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 soil and lakes, destruction of vegetation and ecosystems, and corrosion of building materials, metal structures and cultural relics. >>>More

You're from Changfeng Middle School, right?
Wanton emission of polluting gases, endless exploitation of non-renewable resources, no effective way to organize, waste of water resources, etc., no awareness of conservation and protection. And so on and so forth.
