What is the biggest problem in this world?

I think the economy well mostly in the US but all the job losses and people starving because they can't pay their bills and afford food in the house. This is a very big problem to me because I am one of those families who doesn't have much food or gas money to keep getting to work or keep the electricity on or always pay rent I really think this is one of the biggest problems in the world right now.

The biggest problem in this world is SIN. That's all.

I think worlds greatest problem in present time is terrorism and global warming. If we talk about global warming then we find it affected whole worlds in many ways. So I think world should think about it and try to find some good way of this problems solutions. If soon this problem not solved then one day our earth destroyed completely.

i think the over usage of resources is the problem

I think the biggest problem which has a solution is poverty. There are many hungry people in this world who doesnt have food even one time a day. Having money to eat food is a right of all human being. If we are denying it it is the biggest mistake we are doing. Each country is spending a huge amount of money in war, space exploration. defense equipments etc. A small portion of this is sufficient for givin a source of food to this people.

I think if many people being selfish... Selfish is big problem for me and the world..:-(

The biggest problem is that EVERYBODY WANTS TO RULE THE WORLD!!Think about it. Don't most of the world's problems start here?

Pollution is the greatest problem in this world along with terrorism. There are other huge problem as well such as population, weapon race, poverty etc.

I think atom bomb is the greatest. If many bomb will have used, the World is a 0. Everything will become ashes and dust

The world major problem is global warming because it is not only a single country that is being affected but the whole word because of the continuing growth of carbon dioxide in the atmosphere the sun's heat rays are trap therefore making the world hotter every year. but we can still save our planet by recycling and reusing.I hope everyone will help in making our planet safe and livable.
