Living is altogether a struggle since the advent of mankind due to different reasons such as availability of food, shelter, etc. But in the coming time, it looks like that it would be challenging to live on the Earth. Some believe that more budget should be consumed for research about the life presence on other planets such as Mars. In my view, I disagree with this viewpoint as even if we find life on other planets, humans would make it impossible to live there as well until mankind takes initiative to not to degrade the environment.
