History, as well as life itself, is complicated; neither life nor history is an enterprise for those who seek simplicity and consistency. - Jared Diamond

Just as strawberries are adapted to birds, so acorns are adapted to squirrels, mangos to bats, and some sedges to ants. That fulfills part of our definition of plant domestication, as the genetic modification of an ancestral plant in ways that make it more useful to consumers. But no one would seriously describe this evolutionary process as domestication, because birds and bats and other animal consumers don't fulfill the other part of the definition: they don't consciously grow plants.

Remember that impact is the product of two factors: population multiplied times impact per person.

Those numbers may not sound like a big deal until one reflects that average global temperatures were "only" 5 degrees cooler at the height of the last Ice Age.
