Measures to Be Taken

Destruction of the Tropical Forest

It's generally agreed that the destruction of the tropical forest has a major impact on the world climate. The tropical rain forest is a natural recycler, provider and protector for our planet. It recycles carbon, nitrogen and oxygen, helps determine temperature, rainfall and other climatic conditions and supports the most diverse ecosystem in the world. Deforestation could cause one fourth of all species on earth to vanish in the next 25 years. These forests in Amazonia, South-East Asia and West and Central Africa are being destroyed at an alarming rate of 42 million acres per year.

We have only a few years to attempt to turn things around. We must review our wasteful, careless ways, we must consume less, recycle more, conserve wildlife and nature, act according to the dictum «think locally, think globally, act locally». To my mind, we are obliged to remove factories and plants from cities, use modern technologies, redesign and modify purifying systems for cleaning and trapping harmful substances, protect and increase the greenery and broaden ecological education. These are the main practical measures, which must be taken in order to improve the ecological situation.

Some progress has been already made in this direction. 159 countries-members of the UNO have set up environmental protection agencies. They hold conferences discussing ecological problems, set up environmental research centres and take practical urgent measures to avoid ecological catastrophe. There are numerous public organisations such as Greenpeace that are doing much to preserve environment.

The 5^th of June is proclaimed the World Environmental Day by the UNO and is celebrated every year.
