Air pollution

Air pollution

Air pollution is a very serious threat to our environment.

Big factories

pollute the air.

Car fumes pollute the air we breath.

Destroying forests.

• Cutting down forest damages thousands of acres of land every day. Even if new trees are planted they can not bring back the old forest that was part of a complex ecosystem that cleaned the air.

Water pollution.

• P olluted water affects people’s health.About 1.4 billion people have no access to safe drinking water.

Oil spills

This is the result of human activities: oil spills. Polluted water also causes water animals to die.

Big tankers emit tons of oil into the sea water. Wild life suffers from this pollution.

What do Animals Worry about?

Red Book Defends

Global warming.

• Some scientists are now concerned that the Earth’s surface will warm up too much – to a dangerous degree. This is called global warming.

Litter

• Most cities produce a lot of waste every day. If it is just thrown away or even dug up, it may be around for decades, and could even release dangerous chemicals into the soil.

Chemicals

• Chemicals can threaten the lives of the people that are living or working near by. If toxic or poisonous, liquid chemicals are poured into the water, it is possible to put large populations of people’s health at risk.

Coral reefs

• Environmentalists are worried because many coral reefs are disappearing. Today only 7% of Jamaica’s coral reefs remain and the reefs in the Philippines and Western Indonesia are almost extinct. Tourists damage reefs by putting
• rubbish into the sea.

Noise pollution. There is much noise in the big cities because of air jets, city transport and so on.

Ecological situation in our place.

• I’m worried about the state of the Nekhvoroshcha-novka pond in my area. When I visi-

ted this place in summer I was hurt and disap- pointed by what I found. Water was very muddy.

People throw out dust into the rivers and ponds.

Our attitude towards the environment .

We must keep our native place clean. If we see litter on the ground, we must put it into a litter bin. And of course we must not draw on walls

or trees.

Code of Ecological Rules.

• Do not leave litter.
• Keep the country tidy.
• Respect the life and work of the countryside.
• Grow trees and flowers.
• Do not cut wild flowers.
• Put litter away.
• Do not frighten birds and animals.
• Do not burn fires.

The Earth is Our Home.

• The Earth is a garden. It is a beautiful place For all living creatures, For all human race.
• Food is a treasure From the soil and the seas Clean fresh air From the plants and the heels.

• Helping mother Earth We can peacefully roam We all deserve a place We can call our home.

• The warmth of the sun Turns water into rain It is nature way!
