Today human activities are such that for mere immediate gains is hell bent on tampering with the environment and nature at just about any cost. Each year humans are filling up the environment varied principles reeking with toxicity in alarming measure. Air, water, soil etc are now brimming with poisonous materials. Where on the one hand smoke levels increasing in the atmosphere is harming human health there at the other end nature’s balance is going haywire. With the aim of immediate benefits man tampers with nature and thus it is creating fearful hazards the world over.

According to survey experts industrial units lead from the front in spreading pollution. In smoke emitted by chimneys such elements like radioactive materials, sulfur dioxide nitrous oxide get mixed that directly affect our health and thus varied bodily and mental ailments ensue. In comparison to poor and backward countries wealthy and developed countries lead in manufacturing such products. Each year USA alone emits 1608 million ton sulfur dioxide, 4 million ton nitrous oxide and 506 million ton other toxic principles into the atmosphere. In America the measure of pollution emitted by nuclear power plants is 10 times and in Britain 20 times. Similarly apart from toxicity coming out from industries a big measure of smoke is emitted into air by household cooking. Plants also rot away slowly and emit methane gas into the environment. It definitely affects public health.

Health experts who carry out research opine that the reaction of increasing poison in air recently stared at us in the form of bad effects on human health and plant life. Due to this dire effect both classes on getting afflicted with many types of diseases were rendered useless. Their life span decreased and a lot of decrease set in their working capacity.

It has been seen that industrial technology that let off smoke no doubt affect nearby surrounding areas more yet based on the flow of wind it affects places about 200 miles afar also. This bad effect is seen chiefly on lungs in comparison to other organs. Gases emitted by factories create diseases like coughing, asthma and breath-choking. Even bird groups dwelling on trees on inhaling this poison become sick. Along with rain water these gases land on the ground and its poisonous portion enters grass and other crops. Thus birds-beasts eating this toxic grass become ill. Those who drink their milk or devour their flesh get affected by their toxicity.
