Consequences of the world's problems

There are a lot of global problems that influence the life of people. And measures should be taken to solve these problems. The UNO tries to do something to reduce the negative impact of these problems, but still there are a lot of problems that should be solved.
People pollute air, water, declare wars and use violence to gain their aims; they lie and test bombs, use all resources of our planet and don't think about consequences. There are a lot of religious and fantastic theories that predict awful future to humanity.
But a planet may really change and these changes may be the death of humanity after which the new cycle of evolution will be started.
Moral values are not kept anymore; the only thing that worries people is money. People want to get more and more power, they don't want to do anything and become very lazy, sex becomes more and more available and takes unnatural forms. And all these problems are heralds of some huge catastrophe that will damage everything.
One of the greatest catastrophes that may take place in future is the use of nuclear weapon. There are a lot of versions that tell us how it is going to happen and why. According to different theories it will be used in the World War 3, in the war with aliens, occasionally, by a psycho. The most important thing is that there will be no humanity anymore. A lot of people will die, and those who won't die in explosion will die from diseases that will be caused by radiation. Nuclear winter will come and will kill the rest of survivors.
Our planet has already started to show its indignation. There are a lot of catastrophes and cataclysms. A lot of people die during these catastrophes. Tornados, inundations, conflagrations, droughts are the results of indignation of nature.
So people should thinks about it carefully and unite to solve it.
