Threat to humanity?

I think the greatest threat in humanity is Selfishness and Greed. As what has been manifested, the concept of our sense of responsibility to others was lost as these two things have emerged. People of todays are fighting for money and all about money. The more the money that you gain, the more the power you may have. This is superceded to the real goal that is "the more you give, the happier you live".

Our own minds,our thoughts Mahesh,our perception of life.

Human self-elimination-but through careless means like pollution, over-farming, destruction of habitats, etc. Just a bunch of mindless things that independently might seem harmless but combined with many other similar situations spell disaster for the plant. What harms the plant definitely harms mankind, i.e., human self-elimination. Do I ever think things will get that bad in my lifetime--no, but we are our own biggest treat to the demise of our world hands down. I have faith that we will wake up just before we hit the ground and more of us will be moved into action to save our precious mother earth and thereby ourselves. Somehow man always manages to rise to the occasion when a situation demands it. I have faith in us.

Hello,MAHESH! the man is the enemy of himself.we the people are recklessly diverting the green fields and forest lands for industrialization and habitation and other purposes for which the carbondyoxide in the atmosphereis increasing.it is the main cause of global warming and if this process continues after this century the earth will face the extinction of many species including human race.thank you.

Our resistence to change! All the things that can be considered possible threats actually have solutions and we know them. The only matter is know, implementing those...and in my opinion, this is the problem. We are too resistent to major changes... And this thing has always been an issue, in all the history.

i think the greatest threat to humanity is................HUMANITY. but if eveyone gets there act together, it could also be the greatest savior of humanity.
