The present world is faced with various serious problems.Global warming is one of them.It is,in fact,the increase in the temperature of the earth's neon-surface air.It has a far-reaching impact on biodiversity and climatic condition of the earth.Global warming is certainly a complex natural process.Carbon dioxide is mainly responsible for global warming.Modern age is producing huge amount of carbon dioxide everyday through numerous vehicles,mills and factories and by burning fossil fuels.This carbon dioxide is creating the greenhouse effect.The atmospheric greenhouse gas concentration is so great that the heat coming from the sun to the earth cannot go back upwards.As a result,the temperature of the earth is gradually increasing.Actually,mechanism-based civilization which is increasing population of the world is responsible for this global warming because with the growth of population,the uses of vehicles,mills and factories,the burning of fossil fuels and uses of chlorofluorocarbons are increasing,and thus contributing to the increase in carbon dioxide which ultimately results in the increase in world temperature.
Global warming has far-reaching effects on biodiversity and climate.Consequently,the lives of many wild species are endangered.Climatologists predict that the temperature may rise as much as 4°c midway through the next century and this could catastrophically reduce mankind's ability to produce crops,destroy or severely damage wildlife and wilderness.This increased temperature will melt the polar ice-caps,raise sea level and thus flood the coastal areas of the earth.And if this global warming continues,many habitats will be destroyed and eventually will pose a great threat to human civilization or existence.Global warming is creating various natural calamities such as flood,drought,cyclones,landslides,
Tsunami etc.And these will increase temperature in the atmosphere.
Trees and forest play a great role in maintaining ecological balance by absorbing carbon dioxide and producing oxygen.So,inconsiderate destruction of trees and forest must be stopped and at the same time forestry-plan should be undertaken on a large scale.The use of fuel-efficient vehicles should be promoted as these vehicles have lower emission of harmful gases.Every individual should be aware of the importance of protecting the environment.Besides,eco-friendly technologies must be promoted and must be substitued for the technologies which cause the emission of harmful gases.Global warming is one of the causes of our sufferings and in the coures of time it will pose a great threat to our existence.So,we must try to control it.And with this end in view,public awareness is a crying need in this present context.World people must act unitedly to resist global warming and to save this beautiful earth.
