What do you think about the natural vegetation of your area is it increasing or decreasing day by day
Answers
Answer:
Rapid population increase:
There has been a tremendous increase in India’s population and it has now crossed 103 crores (1.03 billion). An increase in population will decrease all types of natural resources and result in environmental pollution. Ultimately, there will be short supply, as well as deterioration in quality of natural resources. This is because increase in population will increase the demand of natural resources and environment.
At present, the world population is increasing by two per cent every year. The industrialized countries have annual growth rate of 0.5 to 1 per cent and on the other hand the developing countries have the growth rate of 2 to 3 per cent. The per capita use of energy and mineral resources shows a difference between the developing and developed countries of the world. The developed countries consume less but their resources are enough. The population and per capita consumption have a considerable impact on the environment. The world cannot meet the continuously increasing demand for natural resources.
2. Pollution:
We are deteriorating our environment due to increasing population and industrial revolution. We are polluting atmosphere, lakes, streams, rivers by sewage, industrial wastes, heat, radioactive materials, detergents, fertilizers and pesticides. Besides these, we are releasing a number of toxic materials into our surroundings. The uncontrolled and indiscriminate use of pesticides has disturbed the entire food chains by which animals including man are affected.
It has been estimated that average individual has about 7 parts per million (ppm) DDT in his body which affects in long-term. Recent researches have revealed that this proportion of DDT in our body has deleterious effects on heart and liver and higher concentration may cause several other diseases including cancer. Many gases, e.g., carbon monoxide, sulphur dioxide, carbon dioxide and nitrous oxide are known to cause respiratory troubles. The unplanned and uncontrolled industrial growth may adversely affect or destroy the health of the society.
