Now that your objection (increased land use) has been disproven, I am sure you will come to change your outmoded, even Ehrlichian, views on human population size.
Per capita it's still a decline. Personally I would attribute it to increasing yields in the developing world which are due to modern practices, pesticides, and fertilizers. But it doesn't show a decline like in the chart you posted.

Population is not the issue. Stewardship is the issue.
It turns out that, given education, opportunity, and choice, women want an average of far under 2 children.

Given an endless stream of propaganda against traditional values, conditioning to be too picky, conditioning to be afraid of childbirth itself, conditioning to despise men, and conditioning to seek jobs that are not amenable to long-term relationships or child rearing, women are not having enough kids. It is a disaster for our civilization. I know a lot of smart/successful guys who can't find women who want to have kids. There are many other factors in play too but I think this is an engineered catastrophe. We obviously shouldn't continue with exploding populations but few of the armchair technocrats who agree with the direction of things have really understood how bad it is.
