i totally agree with and this is not it!! all the other countries have started to take measures for this problem but India is still sleeping!!!!!!

well, India is finding difficult to manage itself first...so there's no question of leading the world so far....but still if we compare so lets have a look at the following points:

1. almost 90% of India is illiterate(don't be sure of the percentage), so an illiterate country can't lead the world....

2.India is more into castes, politics, religions and less into development.

3.the most important thing is that India doesn't have confidence on itself and is still cursing itself...

So if it goes on so then it is difficult or even impossible to say that "INDIA WILL LEAD THE WORLD WHEN IT CANNOT LEAD ITSELF!!"
