A good fuel should have many desirable characteristics. Some of them are as follows: 1. It should produce a high amount of energy for each unit of mass or volume. 2. It should be easily available and should be easy to transport. 3. It should be economical.

Ozone layer protects life on our earth from harmful rays (U.V. rays) of sun by absorbing these rays. Damage of Ozone layer leads to decrease in absorption of harmful rays of sun due to which these harmful rays reaches to earth's surface and cause harmful effects, so it is necessary to control this dRead more
Ozone layer protects life on our earth from harmful rays (U.V. rays) of sun by absorbing these rays. Damage of Ozone layer leads to decrease in absorption of harmful rays of sun due to which these harmful rays reaches to earth’s surface and cause harmful effects, so it is necessary to control this damage.
Steps being taken to limit this damage are –
(i)To protect ozone layer, the United Nations environment program forged an agreement to freeze CFC production at 1986 levels.
(ii)Chlorofluoro carbons are now being replaced by hydro-fluorocarbons which do not damage the ozone layer.
Even if all the waste we generate is biodegradable, it will have an impact on the environment. This is because too much biodegradable waste cannot be broken down into harmless simpler substances by the decomposers like micro-organisms at the right time. Due to this, the biodegradable wastes will goRead more
Even if all the waste we generate is biodegradable, it will have an impact on the environment. This is because too much biodegradable waste cannot be broken down into harmless simpler substances by the decomposers like micro-organisms at the right time. Due to this, the biodegradable wastes will go on accumulating in the environment and act as pollutants resulting in harmful effects on the environment. For example, the rotting biodegradable waste act as breeding grounds for flies and cockroaches, etc., which spread diseases. Moreover, the rotting biodegradable waste emit foul smell in the environment which makes the life of people miserable.
Non biodegradable wastes cause many problems like - (i)Enter in food chain and damage the organisms of highest trophic level. (ii)Cause toxic effects to living organisms and may cause pollution like soil pollution, water pollution and air pollution in the environment. (iii)Reduced crop yield. (iv)InRead more
