Humans As the Intense Predator: Unbalancing the Food-Chain Unsustainably

By 2015, humans—the homo sapiens species in particular—had become “the dominant predator across many systems”; that is to say, the species had become an unsustainable "super predator."[1] We have had a huge impact on food webs and ecosystems around the globe.[2] Moreover, we have been using more of the planet's resources than we should. By August 2015, for example, humans had already consumed the year's worth of the world's resources.[3] In terms of fossil fuels, the consumption has had an impact on the warming of the Earth’s atmosphere and oceans. Behind human consumption are human beings, so the astonishing increase in human population is a major factor. As a virus-like species incredibly successful genetically over the previous five-hundred years, the self-maximizing feature both in terms of population ecology and profit-maximization may be the seed of the species destruction, and thus long-term genetic failure.
