Why do we feel the need for conservation more today than our ancestors did

We feel a greater need for conservation as, we are facing lot of risk than our ancestors. Nowadays we are wasting so much of resources than our ancestors. For example : water. We are wasting water in so many ways such as leaving running taps without closing it. Natural resources are slowly vanishing by means of people who abuse it because they do not know the limitations of it. Abusing it can cause food shortage and also cause global warming. We need to conserve resources because it is the main source of our daily needs. Remember the 3 R's- reduce, reuse and recycle. Once it would be totally vanished our life would come to an end.

Hope this helps!
