In this logic, people are simply a drain. The fewer, the better. This is circular and denies the role of property rights. The great advantage of the modern market economy is that it takes place within legal structures that create a framework within which diverse market participants engage in mutually beneficial exchange. Everyone expects there to be problems in the case of common properties.
Property owners have strong incentives to conserve resources.
Only when private property rights are threatened, are we faced with dire prospects, including the cessation of technological advance. The global rather than the local perspective ignores the fact that many environmental impacts occur among neighbors and can be resolved in the civil courts, at least in the cases when transaction costs are not prohibitive. The fundamental importance of institutions that define and enforce property rights is again the cornerstone. This is another stunning denial of the historic record, not to mention elementary economic analysis. Malthusian principles ignore the possibility of shifts in technical progress that can dramatically increase the productivity of each unit of natural resources.
