Who knows the information about environmental pollution or environmental damage?

-Reason:

Refrigerant discharged from production and domestic refrigeration equipment; Nuclear explosion, exhaust emission, spraying agent (pesticide)

Causing the increase of chlorofluorocarbons and nitrogen oxides, then passing through the stratosphere, and finally

Leading to the reduction of ozone concentration and the formation of ozone holes.

-Danger:

Increased ultraviolet rays; Strongly absorb infrared rays

-Directly endangering human health (skin cancer, cataracts, respiratory diseases, etc.). );

-Destroying agricultural production and reducing crop yield;

-Destroying the ecosystem, leading to the extinction of biological species (marine life);

Global warming.

-Prevention and control:

-Prohibiting the discharge of ozone-destroying substances;

-Study alternatives to refrigerants such as HCFCs, and reduce and stop using them.

Melting glaciers

-Reason:

Global warming.

-Danger:

Sea level rise, for example (Tuvalu, a Pacific island country, will be forced to relocate all over the country):

Tuvalu, a Pacific island country, is one of the lowest countries in the world. This tiny country with a land area of only 26 square kilometers consists of nine atolls, the highest point of which is less than 5 meters from the sea level, and the highest point of Funafuti Island, the capital, is only about 3 meters from the sea level. Houses in some low-lying areas are almost at sea level, and residents' homes may be flooded at any time when the sea is at high tide. World climate experts predict that the global sea level will rise by at least 80 cm in this century due to the melting of icebergs and rising water levels caused by global warming. Therefore, the "catastrophe" in the Pacific island country of Tuvalu has actually started to enter the "countdown".

In 2003, Tuvalu leaders said in a statement that their efforts to fight sea level rise had failed, and they would give up their homes and emigrate to New Zealand. Tuvalu will thus become the first country in the world to relocate all its population due to sea level rise.

-Prevention and control:

-Reducing greenhouse gases such as carbon dioxide and methane in the atmosphere through some technical measures;

-Actively adapt to future climate change (building coastal dams to prevent seawater intrusion, and gradually changing the types and varieties of crops in a planned way, etc. );

-Reducing the emission of greenhouse gases such as carbon dioxide and methane.
