@Banana Breath,
I agree with you about population growth. However, there are reasonable ways to address it. Simple development projects are the best way to control population growth. There is a strong correlation between the woman's literacy rate and the birth rate, investing in woman's literacy is a obvious reasonable response and an effective one.
The graph you posted is actually a hopeful one. I am not sure how much math you have studied. Do you notice the shape of that graph? It is curving in the right direction (that graph shows the rate of population growth decrease each year).
Of course, that doesn't mean that we shouldn't invest much more in development projects that are both humane and effective at controlling population growth rates.
I don't know if you are really suggesting that we should let people starve as a way to control population growth. I don't think that is reasonable.
