Respected Principal, teachers and friends
Today I am here to speak on global warming. It seems we have greatly disturbed the ecological balance of nature. The rains which used to be in plenty in the past have refused to bless us. What we need is to rise up to the cause of all this. It is a fact that due to global warming, nature has been undergoing serious changes. These have already started showing grim signs of dangers to human life. With the advancement of technology, man has abused nature and therefore nature is now not in her benevolent state. It has been exploited by humans for their own selfish purposes.
It has been reported that due to global warming glaciers and some other snow capped mountains are gradually melting. The result is that these glaciers, which provided a cold condition till now, are fast melting and resulting in the rising of the sea-level.
