In the present world, we are affecting our planet in a negative way with our daily activities. As a result, many species are on the way to extinction. Some think that trying to preserve wild creatures is a waste of money, and they argue that they have no use in this time. I totally disagree with the idea, and this will be proven by analysing the fact that each living kind has a role in our ecosystem, as well as we should protect them because we are the reason for their daying in the first place.
