Ok, let me start:

So, Good morning to my respected teachers and my dear friends.  I would like to speech on the Environment to increase awareness among public about the negatively changing environment. An environment is the natural surrounding which covers and protects us from the natural disasters. However, our healthy and natural environment is getting worse day by day and taking the form of demon affecting everything from non-living to living beings. What we know is two types of environment called natural environment and built environment. The natural environment is one which exists naturally and the one for which man is responsible such as cities etc is called built environment. There are many natural and unnatural factors polluting the whole natural atmosphere.Our natural environment has become hugely changed in the last few decades and has taken form of big and powerful demon affecting the lives of people every single moment. Nature has made everything to run in balance with the natural cycle however many factors causes environmental corrosion. The factors like population growth and economic advancement are considered as the major factors giving rise to many other secondary factors. We must understand the importance of ecological balance and try our best to run it naturally.

Hope it helped.
