Problems

Today, the ecological situation in the world can be described as close to critical. Among the global environmental problems are the following:

Page 4: байкина алина  7 б класс

Problems

- Thousand of species of plants and animals are destroyed or disposed of;

Page 5: байкина алина  7 б класс

Problems

- The forest cover is largely destroyed;

Page 6: байкина алина  7 б класс

Problems

- A rapidly shrinking supply of available mineral resources

Page 7: байкина алина  7 б класс

Problems

- The world's oceans is not only depleted by the destruction of living organisms. But ceases to be a regulator of natural processes;

Page 8: байкина алина  7 б класс

Problems

- The atmosphere in many places, polluted to the maximum allowable size, and clean air is a deficit;

Problems

- Partially disrupted the Ozone Layer to protect against harmful to all living space radiation

Problems

- Pollution of surface and disfigurement of landscapes: the Earth is impossible to find a single square meter of surface, where there were not artificially created by man elements.

Solutions What measures are needed to address global environmental

problems! First of all, we should move from a consumer-technocratic approach to nature to seek harmony with it. For this purpose, in particular, requires a series of targeted measures for cleaner production: Nature-technology, mandatory environmental impact assessment of new projects, creating a closed loop waste technologies.

Another measure aimed at improving relations between man and nature, is a reasonable self-restraint in the expenditure of natural resources - especially energy resources (oil, coal), which have for human life essential. Calculations of international experts suggest that if we start from the current level of consumption (at the end of XX century.), the coal reserves will last another 430 years, oil - for 35 years, natural gas - for 50 years. Time, especially oil reserves, is not so great. In this regard, take reasonable and necessary structural changes in world energy towards expanding the use of nuclear energy, as well as search for new, effective, safe and friendly nature of most energy sources, including space.

Solutions

However, the tangible effect all of these and other measures may give only by joint efforts of all countries in order to save nature. The first attempt at such an international association was made in the early XX century. Then in November 1913 Switzerland hosted the first international meeting on environmental issues with representatives from 18 major countries in the world.

Solutions

Now the interstate cooperation forms a qualitatively new level. There are international conventions on environmental protection (quotas on catches of fish, the ban on whaling, etc.), performing a range of joint development and programs. The activity of public organizations for the protection of the environment - "green" (Greenpeace). Environment International Green Cross and Green Crescent is currently developing a program to address the problem of "ozone holes in Earth's atmosphere. However, it should be recognized that at very different levels of socio-political development of the world's international cooperation in the environmental field is still very far from its perfection.
