Human wasted too much unneccessary resources

Earth is like a giant spaceship with limited resources travelling around the sun due to the gravitational forces. As human evolves, they wasted too much resources, some due to human's own built in element, which they have not manage to understand and control. Human multiply too quickly as well but they do not know how to bring up the young in a proper way. Human are just too self centre and greedy, suspicious and tend to give in to evil thoughts which results in self destruction. They are not using their resources, knowledge, in the way which will ensure their survival with their limited resources. They are acquiring new knowledge and technology, but they do not use it in a proper way. They need to develop their intellectual ability in a more thoughtful way, rather than the selfish way which is exactly what is happening now.
