Global warming and its effects

For thousands of years, people have used their planet for selfish purposes. Cities and factories were built, tons of coal, gas, gold, oil and other materials were mined. At the same time, man himself destroyed in a barbaric way and continues to destroy what nature has given us. Thousands of innocent birds, insects, fish perish through the fault of people; the number of endangered species of animals is constantly increasing; destroyed by thousands of hectares of forest, etc.

Forest pollution

Forest problems are among the most urgent on our planet. If the trees are destroyed, our land will have no future. Along with the problem of tree felling, there is another - pollution of forests. The forest park zone of any city is perceived as a place to relax, and therefore regularly after the people there are traces of their stay: plastic cans; plastic bags; disposable tableware.

Human river pollution

River pollution has been going on for more than two thousand years. And if earlier this problem was not noticed by people, today it has reached a global scale. It is difficult to say whether there were rivers on the planet with more or less pure water, suitable for use without preliminary purification. Sources of river pollution The main reason for river pollution is the active growth and development of socio-economic life on the banks of water bodies.

Environmental pollution

Industrial enterprises benefit the economies of many countries, but ecologies do harm. To date, the following areas have a negative impact on the environment: metallurgy; petrochemicals; machine-building; chemical. As a result of the operation of these facilities, carbon dioxide and sulphurous gases, ash and toxic gases are released into the atmosphere.

Lithosphere pollution

Anthropogenic activity affects the biosphere as a whole. Significant pollution is on the lithosphere. The soil received a negative impact. It loses its fertility and collapses, minerals are washed out, and the earth becomes unsuitable for the growth of various plant species. Types of impacts on the lithosphere The main pollution on the soil is as follows: pollution by chemicals; radioactive elements; agricultural chemistry, pesticides and mineral fertilizers; garbage and household waste; acids and aerosols; combustion products; petroleum products; plentiful watering of the earth; waterlogging of the soil.

Atmospheric air pollution

One of the significant global problems is the atmospheric pollution of the Earth. The danger of this is not only that people lack clean air, but also that air pollution leads to climate change on the planet. Causes of air pollution. The atmosphere gets various elements and substances that change the composition and concentration of air.

Biological pollution

Biological pollution occurs due to anthropogenic impact on the world. Mainly various viruses and bacteria get into the biosphere, which worsen the state of ecosystems, affect species of animals and plants. Sources of biological pollution food enterprises; domestic and industrial wastewater; landfills and landfills; cemeteries; sewer networks.

Anthropogenic pollution

Man is the most dangerous source of environmental degradation. As a result of economic and industrial activities of people, water, air, soil, and the habitat of many species of flora and fauna are polluted. The most dangerous pollutants: carbon dioxide; car exhaust heavy metals; aerosols; acids.

Water pollution

A large surface of the Earth is covered with water, which generally makes up the oceans. On land there are sources of fresh water - the lake. Rivers are the vital arteries of many cities and countries. The seas are fed by a large number of people. All this suggests that there can be no life on the planet without water. However, man neglects the main resource of nature, which led to a huge pollution of the hydrosphere.

Oceans pollution

There are a huge amount of water on Earth, images from space prove this fact. And now there are concerns about the transient pollution of these waters. Sources of pollution are emissions of domestic and industrial wastewater into the oceans, radioactive materials. The causes of water pollution of the oceans. People have always sought water, it was these territories that people tried to master in the first place.

Chemical pollution

One of the significant environmental problems of our time is chemical pollution of the environment. Primary types of chemical pollution - chemical pollutants are formed due to natural and anthropogenic processes; secondary - occurs as a result of physico-chemical processes. People have been caring for the preservation of the ecological situation for several decades, including the developed countries of the world implementing state programs to improve the state of the environment.

Rivers and lakes of Antarctica

Global warming causes glaciers to melt on all continents, including Antarctica. Previously, the mainland was completely covered with ice, but now there are plots of land with lakes and rivers, free of ice. These processes occur on the coast of the ocean. This will be helped by images taken from satellites, where you can see the relief without snow and ice.

Nuclear pollution

Today, there are many types of pollution, and many of them have different scales of distribution. Radioactive contamination occurs depending on the object - the source of radioactive substances. This type of pollution can occur due to nuclear weapons tests or because of an accident at a nuclear power plant.

Ecology of Russian cities

Modern cities are not only new houses and bridges, shopping centers and parks, fountains and flower beds. These are automobile traffic jams, smog, polluted reservoirs and piles of garbage. All these problems are characteristic of Russian cities. Environmental problems of Russian cities. Each settlement has a number of its own problems.

Hydrosphere pollution

The hydrosphere is not only the water surface of the earth, but also groundwater. Rivers, lakes, oceans, seas together form the oceans. It occupies much more space of our planet than land. Basically, the composition of the hydrosphere includes mineral compounds that make it salty. On Earth, there is a small supply of fresh water suitable for drinking.

Ecological problems of the Sea of ​​Japan

The Sea of ​​Japan is located on the outskirts of the Pacific Ocean. It washes the shores of Japan and Russia, China and Korea, being the economic zone of these states. Since the reservoir has the same environmental problems as other seas of the planet, the government of these countries carries out various actions to preserve the nature of the sea.

Environmental problems of the White Sea

The White Sea is a half-isolated inland water body that belongs to the Arctic Ocean basin. Its area is small, divided into two uneven parts - southern and northern, connected by a strait. Despite the fact that the waters of the hydraulic system are very clean, the sea is still subject to anthropogenic impact, which in turn leads to pollution and environmental problems.

Ecology of Crimea

By the beginning of the 21st century, the territory of the Crimean peninsula has already been fully developed by people and is quite densely populated. There are both natural landscapes and settlements, however, the influence of the anthropogenic factor is significant and there are no more than 3% of places untouched by man. Here, rich nature and terrain can be divided into three zones: steppe zone; massif; sea ​​coast.

Types of environmental pollution

As a result of anthropogenic activities, the environment lends itself to various types of pollution. This significantly affects not only the lives of people, but also the state of the climate, flora, fauna, and leads to sad consequences. The main source of pollution is the invention of people: cars; power plants; nuclear weapon; industrial enterprises; chemical substances.

Ecological problems of rivers

One of the pressing environmental problems is the problem of rivers. Every year, the need for water conservation is increasing. Russia is the leader in fresh water reserves, but the water of more than 70% of the rivers is polluted and is not even suitable for technical use. One of the reasons is the lack of water treatment facilities.
