HOW LIFE BEGAN ON THE EARTH
No one knows exactly how the earth began,as it happened so long ago.However,according to a widely accepted theory,the universe began with a "Big Bang" that threw matter in all directions.After that,atoms began to form and combine to create stars and other bodies.
For several billion years after the "Big Bang",the earth was still just a cloud of st.What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the st settled into a solid globe.The earth became so violent that it was not clear whether the shape would last or not.It exploded loudly with fire and rock.They were in time to proce carbon,nitrogen,water vapour and other gases,which were to make the earth's atmosphere.What is even more important is that as the earth cooled down,water began to appear on its surface.
Water had also appeared on other planets like Mars but,unlike the earth,it had disappeared later.It was not immediately obvious that water was to be fundamental to the development of life.What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas.This proced a chain reaction,which made it possible for life to develop.
Many millions of years later,the first extremely small plants began to appear on the surface of the water.They multiplied and filled the oceans and seas with oxygen,which encouraged the later development of early shellfish and all sorts of fish.Next,green plants began to grow on land.They were followed in time by land animals.Some were insects.Others,called amphibians,were able to live on land as well as in the water.Later when the plants grew into forests,reptiles appeared for the first time.They proced young entirely by laying eggs.After that,some huge animals,called dinosaurs,developed.They laid eggs too and existed on the earth for more than 140 million years.However,65 million years ago the age of the dinosaurs ended.Why they suddenly disappeared still remains a mystery.This disappearance made possible the rise of mammals on the earth.These animals were different from all life forms in the past,because they gave birth to young baby animals and proced milk to feed them.
Finally about 2.6 million years ago some small clever animals,now with hands and feet,appeared and spread all over the earth.Thus they have,in their turn,become the most important animals on the planet.But they are not looking after the earth very well.They are putting too much carbon dioxide into the atmosphere,which prevents heat from escaping from the earth into space.As a result of this,many scientists believe the earth may become too hot to live on.So whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.

Cultural Corner
The Green Movement
Some countries are better than others at looking after the environment. In Europe, Germany and the northern European countries work very hard to improve the environment. People in countries such as Germany put their garbage into different bags—paper in one bag, plastic in another bag, etc. The garbage is then taken away and, if possible, recycled. CFCs (chlorofluro-carbons), chemicals which are found in refrigerators and aerosol cans, are not allowed. There are laws that do not allow people to burn too much coal.
In the 1970s, as people learnt more about environmental problems, the "Green" movement began and soon spread all over Europe. The "Green" movement tries to get governments to think seriously about the environment and how to look after it. It collects information about how instry is damaging the environment and gives this information to newspapers.

HOW LIFE BEGAN ON THE EARTH
No one knows exactly how the earth began, as it happened so long ago. However, according to a widely accepted theory, the universe began with a "Big Bang" that threw matter in all directions.After that, atoms began to form and combine to create stars and other bodies.
For several billion years after the "Big Bang", the earth was still just a cloud of st. What it was to become was uncertain until between 4.5 and 3.8 billion years ago when
the st settled into a solid globe. The earth became so violent that it was not clear whether the shape would last or not. It exploded loudly with fire and rock. They were in
time to proce carbon, nitrogen, water vapour and other gases, which were to make the earth's atmosphere. What is even more important is that as the earth cooled down, water
began to appear on its surface.
Water had also appeared on other planets like Mars but, unlike the earth, it had disappeared later. It was not immediately obvious that water was to be fundamental to the development of life. What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas. This proced a chain reaction, which made it possible for life to develop.
Many millions of years later, the first extremely small plants began to appear on the surface of the water. They multiplied and filled the oceans and seas with oxygen, which encouraged the later development of early shellfish and all sorts of fish. Next, green plants began to grow on land. They were followed in time by land animals. Some were insects. Others, called amphibians, were able to live on land as well as in the water. Later when the plants grew into forests, reptiles appeared for the first time. They proced young enerally by laying eggs. After that, some huge animals, called dinosaurs, developed. They laid eggs too and existed on the earth for more than 140 million years. However,
65 million years ago the age of the dinosaurs ended. Why they suddenly disappeared still remains a mystery. This disappearance made possible the rise of mammals on the earth. These animals were different from all life forms in the past, because they gave birth to young baby animals and proced milk to feed them.

Thus they have, in their turn, become the most important animals on the planet. But they are not looking after the earth very well.
