Man and Nature

Man has always been dependant on the natural world surrounding him. Thousands of years ago he used only what he needed: he cut wood to make a fire and a shelter; he picked wild berries; and killed animals to feed his family.

The civilization process has scared the world we live in. The population grew and people needed and wanted more. People build factories to produce more goods and build power stations to produce more electricity. They built more, and bigger, vehicles to transport goods to more and more customers. The Industrial Revolution and the modern technologies has damaged and even destroyed nature.

Today, the Earth is overcrowded with more than 6 billion inhabitants. All life on our planet depends on three basic elements: air, water and soil. The air we breathe, the water we drink and the soil we plant our foods in are becoming polluted. The situation is critical and humankind must find solutions to the most serious aspects we face today: air, water and soil pollution, the greenhouse effect, the holes in the ozone layer, acid rain, serious weather changes, defores¬tation (the cutting down of tropical rain forests) and the disappearance of many animal species.
