Answer:

If we talk about wildlife and its importance and then it would be impossible for us to know each and every single detail how it is important for us. In short if we want to know then we must keep in mind the very first thing which is if we are here then it’s all because of this wildlife because without them even plants and trees and forests have no any existence. It serves i[us in many ways, it helps us if we are hungry usually the people who live in forests their survival is totally depends upon wildlife. They hunt and eat them. Mostly people are non-vegetarian and they totally depend on chicken as it is very good for our health not at extreme level but it is. Food chain as well has its contribution in this wildlife. There is a chain where it’s mentioned that who will eat whom. So this way wildlife has much importance not only in our society, but in whole world.

Answer:

In our area named Mahindra Park there is a garden and in that garden few children of our locality dramatize a play as there are many trees and plants in that garden which are good for any locality/area. So those children are standing by surrounding the tree and protesting not to cut the tree as it provides us too many things like in summers it provides us cool and natural air, and also if anyone is coming facing the sunrays from anywhere then he/she can sit under the tree to relax. Children come and they play under the tree and being the tree of blackberry in rainy season it is a good source for residents to eat a kind of fruit which tastes good. So they are shouting out loud to protect the environment in every way, they don’t ant it to get cut down or destroyed by anybody as they also understand the importance of greenery and vegetation in today’s era where everything is being destroyed because of selfish nature of hum beings. The moral of the play was that we must not harm anything for our own comfort. And the scenario is like Chipko Andolan.

I planted a tree on my birthday and I noticed the growth accordingly which are:

(i) Trees grow faster in the season of rain when it rains heavily then it increases the growth of a plant.


(ii) To grow a healthy and green plant quality of soil, climate, temperature, precipitation and the type of manure and fertilizers are kept in mind, so I have used the good quality of all these things.


I have prepared a report on it:


I planted the tree of mango, which started increasing day by day as I used to water it on time, I noticed that it grew around 2 to 3 cm in each month, nature of tree was quite good and I planted it in the month of July last year and this year I saw the difference as I notice it on daily basis, this tree can be used after growth by society in many forms, like people can sit under its shade and they can eat mangoes as well, if they want to eat pickle and they can take raw mangoes and eat as they want to. Children can swing on the tree and it will also show greenery in our society, in the summer season it will blow the soft and cold wind which sooth our body as natural air is useful for our health.
