Answer and Explanation:
This type of question asks for your personal opinion. I will provide an example of an answer below. Feel free to change anything and adapt it to your beliefs and opinions:
I believe it is due time humankind starts working hard and efficiently to preserve wilderness areas. Even if population growth is unavoidable, we should still be able to come up with solutions for forest areas being logged, wild animals losing their habitats, plants and insects going extinct.
Our growth should not be predatory and end up consuming the very planet we depend on to survive. Take what is happening to the Amazon forest as an example. We are all aware of what the forest's existence means to the huge biodiversity it shelters. Its destruction is done to serve the interest of certain groups, such a loggers - who become so rich by selling its wood in the black marked that they are able to pay mercenaries to threaten and kill native populations and activists. All of that is happening right under our noses. Until when will we do nothing about it? I hope our children will not have to grow in a world that has lost the Amazon forest to greed.
