It wasn't exactly clear what was being reduced. Is the 60% across all mammals, etc., or is it a weighted reduction, such that eliminating all freshwater crocodiles is equivalent to eliminating all cows, even though there are many more cows than freshwater crocodiles? It seems likely the amount of livestock has dramatically increased since the 1970s. How is that reflected in their graphs? I also do not know how they could accurately measure such things. That being said, it is pretty plausible that humans are dramatically messing up the ecosystem, at least in the areas where people live. It's also pretty plausible the destruction is irreversible. I have no idea how we could ever recover extinct species, or repopulate species that have had their natural ecosystems dramatically changed. Our future is going to be a globe mostly populated by humans, cows, chickens and tuna, with a smaller population of dogs and cats, all subsisting on an agriculture of corn. The next stage of evolution will consist of genetically engineered variants of these 7 species.
