One thing bugs me...
In the documentary they say that the human population is increasing exponentially in the past years because of the use of...oil? Because we use oil to produce more food and to transport the food etc...although this might be true..isn't the population also increasing because of a better living environment? Because of the technological advances in medicine? Because people that would have died in the past from certain diseases are now cured? Isn't that another way in which we manipulate nature? By tampering with natural selection? Anyway..nice documentary :D
