Environmental Pollution

 Environmental Pollution:

Environmental pollution is one of the biggest threats to life as we know it. Pollution affects the air we breathe, the water we drink, and the ecosystems we depend on. If pollution severity continues to increase; human, animal, and plant populations will break down as they will not be able to cope with a drastically changing environment. Some factors affect the rates of dispersal and degradation of pollutants. We need to understand the effects of these factors so we know the locations in which pollution will cause the most damage. Today we shall be covering the types of environmental pollution, their effects, and the factors affecting pollutants.

Environmental Pollution Definition

Environmental pollution is any addition of erroneous substances or energies to the environment, that causes a change to the composition of the environment. These variables can be air, water, soil, noise, and light, and changes to their natural values can have profound consequences for ecosystems and human life.

Pollution occurs when harmful materials (called pollutants) are introduced into the environment.

Types of Environmental Pollution:

Air pollution

Water pollution


Soil Pollution

Effects of Environmental Pollution

Anthropogenic air pollution is the major driver behind modern climate change. Greenhouse gas emissions (carbon dioxide, methane, nitrous oxide) contribute to the greenhouse effect in the atmosphere and warm the Earth's surface. Environmental implications of a warming planet are melting ice sheets, rising sea levels, increased precipitation, and more frequent severe weather.

Agriculture:

Overuse of fertilisers can break down agroecosystems. Some wild plants will be unable to survive in a high-nutrient environment and local aquatic ecosystems may be affected. Therefore, the agroecosystem will function less effectively causing crops to be more susceptible to disease, while irrigation of nearby waters will be negatively impacted. The use of unnatural pesticides will contaminate soils and disrupt interspecies dynamics within the ecosystem. Overgrazing of pastures can restrict the ecological succession of soils.

Global Warming

Global Warming Global warming or climate change has become a worldwide concern. It is gradually developing into an unprecedented environmental crisis evident in melting glaciers, changing weather patterns, rising sea levels, floods, cyclones, and droughts. Global warming implies an increase in the average temperature of the Earth due to the entrapment of greenhouse gases in the earth’s atmosphere. Global warming or climate change has today become a major threat to mankind. The Earth’s temperature is on the rise and there are various reasons for it such as greenhouse gases emanating from carbon dioxide (CO2) emissions, burning of fossil fuels, or deforestation. Impact of Greenhouse Gases The rise in the levels of carbon dioxide (CO2) leads to a substantial increase in temperature. It is because CO2 remains concentrated in the atmosphere for even hundreds of years. Due to activities like fossil fuel combustion for electricity generation, transportation, and heating, human beings have con...
