The problems of the Earth.

Acid rain

The smoke coming out the exhaust of cars, chimneys of some plants (especially if they work at very high temperatures) and emerging power plants that produce harmful gases. These gases react with water vapor in the atmosphere and produce acidic substances. When it rains, the rain water mixed with such substances and give a mixture, acid rain, harmful for human beings and for building materials.

Waste

In this country, every citizen produces an average of 1 kg of garbage a day. This amount multiplied by the number of inhabitants of each town and city represents a very large daily production of waste that municipalities are responsible for collecting. Many of the things that are thrown away could be recycled and so, apart from saving energy and raw materials, there is less waste.

The greenhouse effect

Burning coal, gasoline, natural gas or ignite a forest, produce carbon dioxide . This gas is mixed with air and forms a layer that lets in sunlight , but not to go out. Consequently, the Earth heats: the greenhouse effect. If the Earth gets too hot, the polar ice is able to undone and can increase the water level of the seas and oceans.
