essay on our natural environment we live in
Answers
The quality of our life depends on the quality and proper existence of our environment. Environment includes the atmosphere, surrounding geographical area, natural resources etc.
Long ago, people could live according to principles dictated by environment in a way that is harmless to the environment. In these days we are harming and degrading the environment and indirectly harming ourselves – physically and biologically. So the ecological system or ecosystem is affected. Its balance is affected and recycling phenomena of ecosystem are tampered.
Power of the technology and science has enabled the man to exploit the use of environment for selfish and indiscriminate use and create a problem for everyone. The causes are:
1. Deforestation
2. Depletion of water under surface of earth
3. Growth of population
4. Rapid urbanization
5. Extinction of some species, Loss of biodiversity
6. Air pollution (greenhouse gases), drinking water pollution,
river pollution by mixing poisonous chemicals
7. Global warming
8. Depletion of ozone layer
9. Depletion of oil and gas reserves and natural resources like minerals.
We have to adapt to the natural environment. We have to follow regenerative and recycling mechanisms. We need to use resources in a discriminate manner. Otherwise, existence of humanity will become a question. People will suffer with a lot of diseases. Famines and cyclones will become more frequent. Rains will become very untimely and damaging instead of helping agriculture.
Action related to environment needs to be done together by governments of various countries and the United Nations Organization, at a global level. Long term planning and monitoring of actions of private corporations is needed. The young must be educated to live in harmony with environment rather than exploit it.
Natural Environment
The natural environment or natural world encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to the Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity.[1]
The concept of the natural environment can be distinguished as components:
Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms, soil, rocks, atmosphere, and natural phenomena that occur within their boundaries and their nature.
Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from civilized human actions.
In contrast to the natural environment is the built environment. Built environments are where humans have fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is greatly changed into a simplified human environment. Even acts that seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams, and the works of mound-building termites, are thought of as natural.
People cannot find absolutely natural environments on Earth, and naturalness usually varies in a continuum, from 100% natural in one extreme to 0% natural in the other. The massive environmental changes of humanity in the Anthropocene have fundamentally affected all-natural environments: including climate change, biodiversity loss and pollution from plastic and other chemicals in the air and water.
