Civilization has brought people many advantages but its products also pollute damage the enviroment in which we live. In our republic we are only at the beginning of imlementing policies to protect the enviroment.
The biggest problem is air pollution mainly in large cities and in areas with concentrated industrial production. Substances such as sulphur dioxide and nitrogen oxide can cause major changes in the enviroment which can lead to climate changes.
Other big problem is that the great rain forests are being destroyed for firewood and building materials. The rain forests provides 50 percent of the world’s annual production of oxygen. If we lose tropical forests, it will become more difficult, perhaps even impossible, to breathe. With more carbon dioxide in the air, the temperature will rise, the ice caps at the Nord and South Poles will melt, and the sea level will rise which will result in the flooding of many coastal cities.
Several gases have been identified as contributing to the ‘greenhouse effect’, which can also cause climate change.
To solve many of the enviromental problems people should try to use alternative sources of energy, such as solar, water, wind, geothermal and perhaps tidal energies, or at least to burn smokeless fuels.
