What are 5 major environmental problems?

What are the 3 types of environments?

Waste disposal:

Due to the high energy consumption and the high population density of urban societies, large amounts of waste water and waste water as well as household waste are produced. Industrialization and urbanization are the main sources of household, industrial and nuclear waste.

The contaminated water supplies cause many epidemic diseases. Industrial waste consists of chemicals, detergents, metals and synthetic compounds in addition to solid waste and garbage. Thousands of tons of mercury, nitrogen, phosphorus, cadmium, lead, zinc and other waste are dumped into rivers and seas every day.

Food Waste

One third of the food intended for human consumption – around 1.3 billion tonnes – is wasted or lost. That is enough to feed 3 billion people. Food waste and loss accounts for a third of greenhouse gas emissions annually; if it were a country, food waste would be the third highest emitter of greenhouse gases after China and the US.

Food waste and loss occurs at different stages in developing and developed countries; In developing countries, 40% of food waste occurs post-harvest and during processing, while in developed countries, 40% of food waste occurs at the retail and consumer levels.

Loss of Biodiversity:

The extinction of several species or the loss of biodiversity is today a much discussed topic among environmentalists on an international level. Many species are disappearing quickly. It is estimated that 20 to 75 species become extinct every day due to deforestation. This loss of biodiversity is mainly due to the degeneration of the life support system. It forms the basis for life on earth. Biodiversity means the diversity of life on earth.

Diversity is a prerequisite for the long-term sustainability of the environment. Maintaining its integrity is therefore considered essential to the preservation of human life. Biodiversity includes all types of plants, animals and microorganisms, as well as the ecosystem and ecological processes of which they are a part.

Ozone depletion, greenhouse effect and global warming:

All three physical phenomena are closely related. To understand their impact on the environment, we must first know what their meaning, relationship and mode of action is.

Ozone is a form of oxygen found in the atmosphere at an altitude of about 20 to 30 km from the earth’s surface. It is scattered in the stratosphere in the form of a layer about three millimeters thick. This layer acts as a shield to protect the earth from the sun’s ultraviolet radiation.
