Question

What are the main environmental challanges we are facing today? Discuss

Answer 1

Wind and water pollution, global warming due to carbon dioxide emission and use of non-biodegradable material are among the main environmental challenges that we are facing today.

We have to breathe air in order for our body to get a regular supply of oxygen. When the air gets polluted with SPM or suspended particulate matter we tend to suffer from asthma and other lung and heart problems.The atmosphere also has a lot of infectious germs floating in it and this causes no less harm to the human body, like pneumonia and tuberculosis.

The water in some parts of the country contains arsenic, far in excess of tolerable limits for the human body. Unless this is checked or improved upon, people will continue to be maimed for life. The Government should work towards supplying clean, germ-free drinking water across the country as more and more wells and ponds are becoming sources of water not fit for human consumption.

Industrial, commercial and domestic waste must be treated and/or recycled in order to check effluents and wastes from becoming a bigger source for human decay and death. Bio-waste and municipal waste must be tackled properly so that they do not become a source of suffering for humanity. Stagnant water sources like pits, manholes etc must not be kept open as they could turn out to be the ideal breeding ground for mosquitoes, who would continue to merrily spread diseases like malaria and dengue. Plastic and other synthetic material that are not bio-degradable must be recycled.
