Environmental Pollution and Health Hazards

The corollary of industrialization is pollution. The invention in steam, power, textile, iron and steel industry turned the civilized world from agricultural society into an industrial one. Factory system brought forth large industrial town. The factories and their labors are daily burning large amount of coal and petrol daily. Tons and tons of carbon dioxide, sulphur dioxide and other gases are daily churned into the atmosphere. Thus the air is polluted more and more.

As the science advances, a man invents more machines. Millions of cars and buses run on the road emitting fumes of diesel and petrol. Air pollution increases at even faster rate. Factories have to get rid to their industrial waste. It is cheap to ump these into nearby sea or river. More and more towns are coming up all over the world and the sewage is passing into the rivers and lakes. Pressure of population forces man to increase the food output. To protect crops from insects he sprays insecticides. When rains come, most of these harmful materials are washed into the tanks, ponds and rivers. Water is polluted. The incidence of cancer, diphtheria, asthma and other allied diseases have been increasing at a rapid rate all over the world.

Trees purify the air by drawing carbon dioxide, but man is felling hundreds of trees daily. The discovery of nuclear energy has darkened the situation much more. Environmental protection agencies are trying hard to find out a clean and inexpensive fuel. Only god knows when they are going to succeed.
