The concern for bees is appropriate, but it should not be ignored that bats, also effective polinators, are also under threat from what appears to be an undiagnosed fungal infection that has caused large reductions in populations.

And aside from the possible loss of polinating species, the sheer size of the increasing population (based on current growth forecasts) may outstrip our ability to feed them all even with current production capacities.

Predictions that our population will soon outstrip our ability to feed everyone go back at least to Malthus, but a recent report on agricultural production capacities doesn't paint a very rosy picture, even though it assumes that current production will continue to grow at what likely are "optimistic" rates.
