A step taken today can make a better tommorow. We can prevent, by taking many precautionary steps like
1. Improving the education level.
2. Teaching how to express feelings.
3. Bringing all the human race to equal status without any differences.
4. Improving life standards of poor,No racism: no one should make different que if he is an asian/afro.
5. Quick justice and Justice for all.
6. The world should be bipolar not unipolar like today:in a sense that there should be two or more super powers who represent different people all over the world, unlike today one race of monkeys dominating over majority. Or htere should be none to dominate.
7. Every person in a state must be made clear that his life is reponsiblity of state and the state will protect him. A feeling of being safe on planet just like a person feeling safe at home.
8. Every one should know that other also do have right to live and Its GOD who will punish/bless for evil/good. (Don't know what an athiest would think! )
9. time should be spent on betterment of humanity(medicaly and financly) rather than spending on weapons.
10. People should show respect to others religious beliefs( this is the major cause)
But on the other hand this is FATE of humanity. Because humans are only species which stock for tomorrow!
As for the Terrorists the only solution is bullet! Because they are corrupted minds without any ability to understand, they are only robots programmed to obey their master. And their master are using religion to corrupt these young souls. I read newspaper daily, there is a news of blast! I'm 21 not seen much in life But i know one thing that the life goes on, very much like usual. This is what those terrorists don't want from us they want us to sit in our houses and die with fear.
They want us to obey them, obey their falsehood! Its the fear of extinction they face! Terror is the biggest tool used to make others obey even its fowl!
