You might as well say climate change is a myth. We're out of agricultural space. Everything that means decreasing yields is a bad idea. The population growths, however land does not - it might even shrink due to climate change. While the high food waste is usually named as THE problem, it is only part of it and a wasteless utopia is far, far away - and stopping waste in place A doesn't really help people in place B.
This is not remotely true, unless you buy into the ridiculous Ausubel et al paper. Most conservative projections have it at 2040 for peak arable land, which is not the same as being out of agricultural space, and certainly not the same as denying climate change.
Efficiency of arable land per hectare is through the roof and continues to improve every decade by increasing multiplicative factors due to consolidation, regulation, and technology.
The problem is not food development, arable land, or generating calories at all. It is entirely in the distribution of the food and the political ramifications of such.
You're absolutely right - to add on, it's also the need to better disseminate farming technologies to people in the developing world, who get poor yields compared to Western farms (both organic and conventional).
