Up in the sky
When we look up, we see the clouds and the blue sky. But there are other things in the sky that we don’t see. Some of these are harmful to the Earth.
What happens
When power plants burn coal to make electricity, and when cars burn gasoline, invisible gases are released into the air. Some of these gases can mix water and make it acidic, like lemon juice or vinegar.
What can happen
Sometimes the gases get into rain clouds, where they get mixed in with rain or snow. Then the acid falls back to earth with the rain or snow. This is called acid rain.
Bad news
Acid rain is extremely harmful to plants, rivers and lakes, and the creatures that live in them. In some places it is killing forests. And it pollutes the water that animals and people need to drink.
Our mission
It’s very important for us to stop making acid rain. One good way to do that is to drive our cars less. Another good way is to save energy. The less energy we use, the less coal those power plants will have to burn.
You and your family can save energy in lots of ways. Saving energy means saving the Earth. To find out more about what you.
3. POLLUTION
Man has been trying to make his life easier for many centuries. In doing so, he invented machines and instruments. They have been working – and polluting the world we live in.
In this world around us, there are two things that do not belong to any one country: air and ocean water. In both the air and the water, there is much pollution. People are concerned about the air and the water used by everyone, and they are also concerned about the future of the Earth.
One of the most important pollution problems is in the oceans. Many ships sail in the ocean water – fishing ships, some ships carrying people, some carrying oil. If a ship loses some of the oil in the water, or trash from the ships is put into the ocean, the water becomes dirty. Many fish are dying in the sea, others are getting contaminated. Fishermen catch contaminated fish which may be sold in markets and people may get sick from eating them. Fish may also move to another part of the ocean. Lakes and rivers are getting, too. Some beaches are considered dangerous for swimming.
The second important problem is air pollution.
Cars and factories pollute the air we use. It also destroys the ozone layer which protects the Earth from the dangerous light of the Sun.
Another problem is that our forests are dying from acid rain.
This, in turn, affects the balance of nature.
If we want our children to live in the same world we live in, or in a better and healthier world, we must learn to protect the water, the air and the earth from pollution.
