6 6 Greenhouse Effect Global Warming (increasing of the Earth's temperature)

7 7 Ozone Destruction In the 1970s, scientists found out that human activity makes harm to the ozone layer, which protects the earth from the sun's ultraviolet rays. Without this layer, which is about 40 km thick, no life could survive on the planet In the 1970s, scientists found out that human activity makes harm to the ozone layer, which protects the earth from the sun's ultraviolet rays. Without this layer, which is about 40 km thick, no life could survive on the planet

8 8 Acid Rain, form of air pollution Forest Damaged by Acid Rain Forests, lakes, ponds, rivers, etc are being severely damaged by acid rains. Acid rain is caused by the combination of chemical stuff with water in the atmosphere. Acid rain is caused by the combination of chemical stuff with water in the atmosphere.

9 9 W A T E R P O L L U T I O N Acid rain is a major global problem. Acid rain is a major global problem. Acid rain destroys metals, buildings and monuments, kills vegetation, poisons water and soil. Acid rain destroys metals, buildings and monuments, kills vegetation, poisons water and soil. It is estimated that each year 10 million people die worldwide from drinking contaminated water. It is estimated that each year 10 million people die worldwide from drinking contaminated water. Polluted River In The United Kingdom The pollution of rivers and streams with chemical contaminants has become one of the most critical environmental problems of the 20th century.

10 10 Oil Spill Clean-up Workers use special nets to clean up a California beach following an oil tanker spill. Tanker spills are an increasing environmental problem because once oil has spilled, it is virtually impossible to completely remove or contain it. Even small amounts spread rapidly across large areas of water.
