WHAT ARE GLOBAL ENVIRONMENTAL PROBLEMS?
Environmental problem is one of global problems of modernity. It is closely related to issues of ecological security and ecological crisis. Environmental changes under human influence became global, i.e. affecting all countries of the world, therefore they were called global.

ENVIRONMENTAL ISSUES INCLUDE:
Deforestation. According to the reports of the
Organization for food and agriculture of the UN, deforestation continues around the world with great speed. Lost each year 13 million hectares of forest, whereas it grows only 6 Ha. This means that every second, the planet disappears forest the size of a football field.

The reduction of biodiversity. Humanity as a species with great abundance, and habitat leaves no suitable habitat for other species. Need intense expanding the area of specially protected natural territories for conservation of species under threat of extinction, as well as strict regulation of the extinction of commercial valuable species.
Water pollution. The danger of water pollution is that people is largely composed of water and to remain human, he must consume of the water, which in most cities is difficult to name suitable for drinking. About half the population of developing countries has no access to clean water, forced to drink infected with pathogens and therefore doomed to a premature death from epidemic diseases.

Waste. In nature annually more than 50 billion tons of waste energy, industrial, agricultural and domestic sectors, including industrial enterprises - more than 150 million tons Into the environment emit about 100 thousand synthetic chemicals, of which 15 thousand require special attention.
The land degradation. People with their own hands makes the surface of the Earth in the likeness of Mars, forgetting that it is different from our planet one significant detail: on it there can not be life.All the more dangerous becomes the phenomenon of soil erosion, as the fertile soils on the planet becomes smaller and it is vital to preserve at least what is available at the moment, to prevent the disappearance of this single layer of earth's lithosphere on which plants can grow.

We brought only the most important and the most urgent global problems, in fact there are many more. It only depends on us how will worsen the situation on our planet further. The people themselves must monitor the environment that surrounds them. The methods and techniques may be different. For example, seminars on environmental issues, or community work days to clean up areas contaminated by household waste.
