First tell about u- ur name, and class.
Then, start with nature. Nature gives us all the things in outr life. It just gives us, without any expectation. Even when we destroy it, it will not do bad for us, it continues to help us.
This is the specialty of the nature.
What we are doing for the nature??
We are cutting the trees,
Spoiling the environment,
using more and more plastics, etc...
Though the nature is helping us, and giving us a lot of things.
Then, u may conclude by saying that,
We people are cutting trees and plants, causing Global warming, and acid rain;
and, we are using lot of vehicles causing excessive release of the smokes, and green house gases.
So, it is our duty to keep our nature clean; to protect our nature; and to get benefited.
Then, say Thank you, for the people who are all gathered there.
Hope this will help you.
