The destruction of the Ozone LayerThe destruction of the Ozone Layer

Chemical reactions produced by the interaction among Chemical reactions produced by the interaction among gases (carbon dioxide, hydrogen, nitrogen, etc )in the gases (carbon dioxide, hydrogen, nitrogen, etc )in the atmosphere has caused the destruction of the Ozone atmosphere has caused the destruction of the Ozone Layer.Layer.The Ozone Layer protects the surface of the Earth from The Ozone Layer protects the surface of the Earth from Ultraviolet radiation of the Sun. Ultraviolet radiation of the Sun.As a result, the Ozone Layer hole over the Artic is in As a result, the Ozone Layer hole over the Artic is in expansion.expansion.

The photosynthesis is a Basic The photosynthesis is a Basic process for the life on the Earth.process for the life on the Earth.The carbon dioxide is transformed The carbon dioxide is transformed into oxygen which is a vital gas into oxygen which is a vital gas for human beings.for human beings.Due to deforestation the Due to deforestation the adequate levels of gases in the adequate levels of gases in the atmosphere and the natural atmosphere and the natural proceses are seing modified, proceses are seing modified, affecting biosystems.affecting biosystems.

When the fuels When the fuels are burnt to are burnt to produce energy, produce energy, carbon dioxide carbon dioxide and other and other chemicals are chemicals are spread into the spread into the air.air.It causes It causes Pollution.Pollution.

Commom fossil Commom fossil fuels are: coal fuels are: coal and oil. They are and oil. They are used to produce used to produce electricity and electricity and also for also for factories, factories, heating, and car heating, and car engines. engines.

Melting of the Melting of the PolesPoles

Due to Due to global global warming, warming, ice sheets ice sheets are melting are melting quickly in quickly in both poles. both poles. It is It is expected expected the rise of the rise of sea level in sea level in a near a near futurefuture..

As a result of constant and increasing fossil combustion, the atmosphere contains more chemical gases and acids than ever. before.Sulfur dioxide and nitrogen oxide are released from power plants and factories pipes into the air.The deposition of these dangerous substances on the ground (trees, houses, rivers,animals…) occurs when they fall through rain, smoke or dust.

Waste and rubbish materials can be recycled. Disposal containers to dump plastic, glass, organic waste are available in cities.Clean energies are the alternative to polluting fuels.. Wind turbines can produce electricity cheaply.
