Importance of Environment :
The environment is very important for every living being. No one can survive without the environment. It matters a lot because planet earth is the only home for human beings. It provides food, air, water and millions of other things. Humanity’s entire life-supporting system totally depends on the well-being of all the species living the earth.
We call it the biosphere. Biosphere means one global ecological system under which all living things are depending upon each other relatively. In the ecosystem or overall biosphere, there are some smaller ecosystems like the rainforests, deserts, oceans and the tundra.
An ecosystem has both living and non-living parts. It can be terrestrial or aquatic. It explains the valuing ecosystem services: towards better environmental decision making that is available through the National Academy Press. The non-living things are like soil, water, air, nutrients, and living elements are the plants, micro-organisms, animals and human beings.
A healthy ecosystem consists of all the chemical elements and nutrients that circulate in a cycle while supporting billions of species. The species helps in the process of cycling the elements when they produce any food. It also happens during their eating, going about their lives and even though their deaths. In this process creation of a variety of goods and services takes place that is very useful for human beings.
The environment is all that surrounds us. It can be a living or a non-living thing. It includes many forces that are physical, chemical and other natural forces. These living things live in their environment. They consistently react with it and adapt themselves according to the conditions in their environment. In the environment, there are various interactions between the animals, plants, water, soil and other living and many non-living things present in nature. Since everything is a part of this environment of something else, we use the term environment talking about various things. People in different fields use this term differently.
ENVIRONMENTAL POLLUTION :
Environmental pollution is one of the most critical threats faced by our planet in the present day scenario. This is a global issue, which is seen commonly in all countries, including the third–world countries, irrespective of their developmental statuses.
What is Environmental Pollution?
Environmental pollution is when human activities introduce contaminants in the environment, thereby leading to the disruption of the routine processes, causing irreversible changes in the environment. The agents causing pollution are called pollutants. Pollutants are substances occurring in nature or created because of extraneous human activities. Pollutants can also be forms of energies let out in the environment. Based on the pollutants and the pollution caused in the components of the environment, the environmental pollution may be classified as follows:
i. Air Pollution
ii. Water Pollution
iii. Soil/Land Pollution
iv. Noise Pollution
v. Radioactive Pollution
vi. Thermal Pollution
Any natural resource found in the environment, when used at a higher rate than the ability of its restoration, leads to depletion, thereby causing environmental pollution. This will lead to the declination of environmental quality and is evidenced by the loss of biodiversity, loss of flora and fauna, the introduction of new diseases and stressful life in the human population, etc.
