Climate change plus human pressure caused large mammal extinctions in late Pleistocene
...it was between 50,000 and 10,000 years ago, when a combination of climate change and human pressure resulted in the extinction of two-thirds of all large mammals on the planet. Paleobiologist Anthony D. Barnosky and his colleagues reached this conclusion after review of studies of the extensive large mammal, or ...Lycopene slows human prostate tumour growth in mice and combined with vitamin E is even better
