unfortunately humans are the least advanced creatures on the planet. whilst every other creature has a natural harmony with it's environment, humans spread across the world and kill everything, using up all available resources until the world will one day run out. notice how overcrowded the world has become, yet still we strive to live longer and be stronger thru the uses of technology and medicine. but our uses of technology and medicine have made us weak, and unable to evolve like other animals do. Diseases are becoming widespread because, unlike other animals, we cure the weak and allow them to survive. This means that the weak genes are passed on from human to human. animals use a process called natural selection, whereby the weak die off and the strong survive, meaning that their species are every evolving and becoming stronger and more superior. for example, if a human has a disease, we cure it and they live on, but they pass their weakness ot that disease on to their offspring, and the weakness spreads throughout further generations. If that person had died, as natural selection would allow, the weakness would not be passed on, and the following generations would be only those imune to that disease. Therefore, humans are weak creatures, and if our technology was taken away from us we could not survive. we rely on others to proivide our food, energy, build our houses and work day in day out in a meaningless life trying to earn more money to buy more things that we can't provide for ourselves. sorry if all that seems a bit philosophical...just my ramblings...
