Global warming is the rise in the average temperature of the Earth’s atmosphere, caused by due to increasing concentration of green house gases in the atmosphere of the earth. These greenhouse gases are mostly produced as a result of human activity. Global warming has lately become a serious issue, which threatens to disrupt the basic balance of the environment and causes large scale destruction.

Climate change and its environmental and economic effects:

Economical systems are the very foundation of our society in science, agriculture, social and economic planning. Environmental balance is very important to survive people. Greenhouse gases produce the greenhouse effect, which traps heat near the earth’s surface, maintaining a relative constant temperature. However, many human activities increase the amount of greenhouse gases in the atmosphere. As concentrations increase, the temperature of the earth also rises.

1. Oxygen topmost essential for living things; if trees will destroy, the sources of oxygen decreasing day by day.
2. Cropland supplies food, feed, and an endless array of raw materials for industry such as fiber and vegetable oils.
3. Forests are the sources of fuel, lumber, paper, And countless other products, and house variable watersheds that provide drinking water for growing urban areas.
4. The oceans and fresh water produce food for individuals and resources for industry.

Global warming creates dangerous effects on environment. All of effects directly attack on environment. Now i want to discuss how agriculture, environmental balances, human beings will be destroyed by global warming.

Agriculture:
The potential impact of climate change on agriculture is also of great concern. An authoritative international study of the impacts of global warming on foods security concludes that as many as 63 to 369 million additional people could be at risk of hunger in 2060 if global warming is not controlled.

A key finding of the study is that crop production is likely to decline in developing countries. Could increase in developed countries. global warming rises temperature and kills plants!
