Of course it is not, and that is not what he is actually saying. He is not saying that we should refuse to aid those in genuine need, through the sending of food and aid supplies in times of draught and famine.
What he is saying is that such aid programmes can only ever be a sticking plaster. The long term problem remains, and what to do about it?
He advocates global population control, and again I would not disagree with him that this is an important issue.
But promoting the widespread use of birth control in areas with high infant mortality, heavy reliance on generational family labour, poor or non-existent education systems and poor, under-developed agrarian societies, which just so happen to be in those areas of the globe most at risk of natural disasters and most at the mercy of climate phenomenon is always going to be difficult.
First you need a better developed, industrialised economies, with more sophisticated infra-structure, including systems to allow for greater protection against natural phenomena, like draughts or famines or floods.Then you need to dramatically improve clean water and sanitation systems to dramatically lower the child mortality rate. Then you need much better education systems and better standards of living. And then, finally, you can promote, with some effectiveness, effective birth control measures.
All these changes do not happen overnight,so it is beholden upon all of humanity to aid each other in times of crisis.
