What are the major environmental problems facing the world? Give examples of some data stories stat

Global climate change, ozone layer depletion and depletion, acid rain pollution, land desertification, water crisis.

Global warming, melting glaciers, soil erosion, serious desertification, industrial exhaust gases, automobile exhaust air pollution, etc.

Today's world is facing 10 major environmental problems:

1) Global warming.

Carbon dioxide, methane.

Greenhouse gases prevent heat from the Earth's surface, and a warming climate causes glaciers at the poles to melt, causing sea levels to rise and flooding coastal areas.

2) The ozone layer is destroyed. The ozone layer absorbs the sun's ultraviolet rays.

Ozone-depleting substances emitted from human industrial and living activities can destroy the ozone layer, leading to cancer and cataracts in humans.

is elevated.

3) Biodiversity reduction. The main reasons are overhunting, industrial pollution, etc. The decline in biodiversity will gradually disintegrate the foundations of human existence.

4) Acid rain. Spread. Large amounts of sulfur dioxide.

Nitrogen oxides are emitted into the atmosphere and dissolved in water when it rains, forming acid rain. Acid rain is corrosive and can damage crops, cause lakes to acidify, and fish to die.

5) Sharp loss of forests. Over-harvesting by humans, combined with forest fires, has led to a sharp decline in forest area. Deforestation leads to soil erosion and frequent flooding.

6) Desertification of land. Human activities such as overgrazing, mining, and road construction have degraded grasslands. At present, the global area of desertified land is almost equal to the land area of Russia, Canada, the United States and China combined.

7) Shortage of resources. The most serious of these is the shortage of water, arable land and mineral resources. About 1 2 people worldwide are currently threatened by water scarcity. Industrial and urban construction projects are constantly occupying arable land, which makes human beings face the dilemma of insufficient arable land.

8) The water environment is seriously polluted. Industrial sewage makes the otherwise clear water body black and smelly, and bacteria breed. In China, less than 30% of the water sources of the seven major water systems can meet the water quality standards of drinking water sources.

9) Air pollution. Suspended particles are inhaled by the human body and can easily cause respiratory diseases. The secondary air standard is suitable for human life, but there are currently only 1 3 cities in China that have air energy for the vast majority of days in a year.

Reach Level 2 standards.

10) Solid waste disaster. Solid waste includes municipal waste and industrial solid waste. Garbage contains harmful substances, and random stacking can pollute the surrounding air, water bodies, and even groundwater.

It is recognized as the world's top three environmental problems: acid rain, ozone layer depletion, and the greenhouse effect.
