Carbon dioxide from industrial smokestacks pollute the atmosphere.

Carbon dioxide contributes significantly to global warming.

It may cause respiratory diseases, poisoned lakes and rivers, and damaged forests and crops.

Smoke from Industrial Smokestacks

Pollution from Cars

Automobile gas affects the human helath,

the health of animals, plants and the atmosphere.

Carbon dioxide affects significantly to global warming .

Greenhouse Effect

Global Warming

( increasing of the Earth's temperature)

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

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.

W A T E R P O L L U T I O N

• Acid rain is a major global problem.
• 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.

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.

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.

Toxic Waste in Love Canal

Residents of the Love Canal area in Niagara Falls were forced to evacuate when hazardous ( опасные) wastes leaking from a former disposal site threatened their health and homes in the late 1970s.

ANNUAL HOUSHOLD WASTE

!!!

Overflowing Landfill

An average person may produce a ton of trash in a year, that rapidly overflows local dumps. Sometimes cities have to remove their waste to other areas, although up to 90 percent of the material might have been recycled.

Recycling Aluminum Cans

To keep the natural resources, many industries and individuals recycle waste aluminum. At this collection point, the Alcoa Recycling Company in New Jersey processes aluminum cans into large bales.

Composting and Organic Waste

Waste from the garden, yard, and table does not have to be thrown away. It may be condensed and reused as a fertilizer through a process called composting.

The compost is then applied to plants as a fertilizer.
