When DDT was sprayed for the first time, some of the house flies which were not capable enough to withstand the adverse effects of DDT , eventually died. And the butterflies that survived through this, were having a natural resistance against DDT. Now, with time these DDT resistant houseflies mated and produced offspring that had genetic trait of resisting DDT by birth. This is the reason, why houseflies after ten years were as abundant as ten years back when the control program was started.

It is crucial to be aware of and respect the environment because you live off of it. Our earth provides us air, energy, food, and the resources we need to live. When we don't keep our environment clean, and disrespect it, it won't be in as good condition as it should be, and could potentially die out from being mistreated. We need to be aware of our environment to know what we need to do to cater to its needs, so it can cater to ours.
