Global Warming:

Global warming is caused by the carbon dioxide and other greenhouse gases that released from the industries. Those gases accumulate in the Earth's atmosphere and trap heat from the Sun. Then it radiate the heat to the Earth, hence rising the temperature of the Earth and also warming the oceans.

>> Industries
The industries are responsible for causing the global warming as they release the harmful gases into the air and trapped in the Earth's atmosphere. These gases were produced by burning fossil fuels, such as coal, oil and natural gas to power the machines to generate electricity. Burning of these fuels produces carbon dioxide, which increases the rate of global warming.



>> Deforestation
Forests are cut down to get that piece of land for human activites, such as :
· Build houses and villages.
· Grow crops
· Damming rivers to prevent floods, store water for irrigation and generate electricity.
· Extracting minerals from the ground, and processing and manufacturing them into products.
· Constructing road and rail networkds across land to allow people to move themselves and goods from place to place.
· Manufacture papers and furnitures

It improved the quality of life for humans, but this can cause greater harm to the Earth, especially the oceans
Lesser trees to reverse the rate of global warming, therefore it reduces the quality of the air for living things to breathe. It also affects the amount and quality of the water.
In order to clear land, incineration and burning of forest plants are needed , which releases carbon dioxide that also ocntributes to global warming.
Deforestation also causes flooding, erosion and landslides due to reduction of soil cohesion
