Question

a short note on environment

Answer 1

environment is the most important thing to us ithin the overall biosphere, or ecosystem, there are smaller ecosystems like the rainforests, marine ecosystems, the desert and the tundra. When any of these systems are off kilter, it impacts the entire planet. All of the  environment problems that exist have far-reaching implications for the health of our planet and its inhabitants. For example, global warming causes a rise in sea levels which effects marine life. The rising sea levels also cause land erosion which harms the habitats of animals living by the coast. Global warming also melts polar caps and leads to arctic shrinking. This endangers the polar bears and other arctic wildlife. Since the icecaps are made of fresh water, they will throw off the saline levels in the ocean which will affect ocean currents. Furthermore, the ice caps reflect light. As they disappear the Earth will get darker and absorb more heat increasing the Earth's temperature.

Answer 2

We live on earth in different types of surroundings. This surrounding is our environment. We eat, breathe, clothe ourselves, reproduce and then die. The next generation comes and the cycle goes on; and the human race flourishes on earth.
The physical environment on the earth provides favorable conditions for the existence and growth of different life forms, including man. These living beings constitute the biological environment. Both the physical and biological environments are in a close interaction with each other and form a stable self perpetuating system.
In prehistoric days man lived in harmony with nature but in the course of his evolution man has developed a new type of environment, the man-made environment. Man is a social animal; the sociol-cultural environment also plays an important role in his life.There are three types of environments i.e. natural, man-made and social environment.
The environment is constantly changing and this affects life on earth; some these effects can be lasting and irreversible. So we must realize that we should be concerned about environment.
