What can people do to help nature ? What must people do to protect wild animals ?

How the future will be difficult to predict. Science fiction writers describe the future in different ways. But in most cases, they are similar in one thing: in human society there will be robots that will have artificial intelligence, and people will begin to move to other planets. Perhaps it will be so. After all, once people thought that the earth is flat, but when they began to surf the ocean and open continents, they realized that the situation is quite different.
Over time, people will also begin to discover new planets, as once opened new continents. A person can not sit still, he is committed to the future, in front of him a lot of secrets that he will reveal.
Someone afraid of the future because the unknown is always scary. What a man a few hundred years, no one knows. A lot depends on the person, he creates history and builds the future. Perhaps the most important thing is that people take care of the future for the new generation, so that they do not have to suffer from diseases, lack of food. We must take care of the future, about the state in which the planet earth will get to our descendants.
