Man's environment1972

Planet Earth What is the environment? The human environment simply means everything that surrounds him. Some people live in a city environment, for others it is the countryside. But the air we breathe, the ground on which we stand, and the water we drink are all part of our environment. Thousands of years ago, the environment of the people was limited. Not even the nomads moved too far away. Gradually, people began to travel farther and realized that their environment was more extensive than supposed. Currently, you can go anywhere on earth within hours. The news from one country reach quickly another and the Earth appears to be smaller.
