Ten environmental disasters are threatening humanity

Humanity is more than ever before 10 disasters caused by itself, without the global expansion to solve the endangered competition is not a distant future.

Environmental disasters threaten people and the earth

1. Land is degraded

Productivity of cultivated land in 110 countries (total of 1 billion people) is declining. In Africa, Asia and Latin America, the situation of land degradation is serious due to the loss of forest cover, exploitation for overproduction of crops and livestock. The bare land (which is no longer available for cultivation) grows and rains and wind erosion.

In some areas, the annual amount of soil erosion is 100 tons / ha. The misuse of fertilizers and pesticides, the toxic dust from polluted air settles down, the toxic waste disposal . makes the contaminated soil become unrecoverable.

2. Climate change, exhaustion of energy sources and greenhouse effect are threatening all humanity

According to 2500 experts representing countries, rising sea levels, many densely populated areas (Bangladesh, coastal areas of Southeast Asia, islands in the Pacific Ocean, Indian Ocean) will be submerged. seawater. Temperature rise has serious consequences for agriculture and ecosystems.

3. Reduce plant and animal diversity

Due to the process of urbanization and agricultural development to meet the rapidly increasing population, reduce the area of ​​forests and environmental pollution, the areas which are wild areas are increasingly narrowed, leading to the extinction of thousands of plants and animals every year.

4. Decreased forest area

In the past decade, the situation in the tropical countries has been greatly reduced. From 1980 to 1990, 1.50 billion hectares of forest - often called Earth's green lung - disappeared.

5. Freshwater resources are threatened

According to experts' estimates, at the beginning of the next century, a quarter of the Earth will be short of fresh water for a long time. Remember, we can't create water. Can only save and protect water resources only.

6. Chemical pollution

Millions of chemical compounds emitted by the industry are currently in the atmosphere, in soil, in water, in plants, in animals and in our own bodies. All natural ecosystems, floating ice on the ocean surface . are polluted. Organic chemicals, heavy metals and toxic products are all in the food chain that we eat every day, threatening people's health and flora and fauna, causing cancer and reducing fertility. of land.

7. Unorganized urbanization

The number of extraordinarily large cities by the end of the century will increase to 21. Living conditions in these cities will become worse: cramped, congested traffic, unsanitary conditions, new diseases appear.

8. The surface of the ocean and ocean will increase excessively

Sea level rise will sink many residential areas and cultivated land. The sea currents are altered, causing unpredictable climate changes and major natural disasters. The sea surface is contaminated.

9. The air is heavily polluted

The main focus is on human health, causing respiratory diseases, rain damage to crops, construction works, fresh water used daily .

10. Ozone layer holes are getting wider in the polar regions

The intensity of ultraviolet radiation increases, causing skin cancer and other diseases.
