Yoga for the back for million years ago, at the end of the Mesozoic Era in the Cretaceous-Tertiary transition and was responsible for the demise of the dinosaurs. In this case, the available evidence suggests that the impact of a giant meteorite hitting Earth was a major factor in the extinctions. Many scientists believe we are now in the middle of the sixth mass extinction, the consequences of which will dramatically diminish the biological diversity of life on Earth. However, this time the cause is the all-pervasive influence of human societies on the natural environment. The human activities that have done most harm to biodiversity are habitat loss, fragmentation and transformation, introduction of exotic species, overexploitation, pollution, and, most recently, climate change caused by emissions of greenhouse gases into the atmosphere. The impacts of these different threats vary considerably depending upon the ecosystem. In the marine environment, overexploitation has significantly diminished fish stocks around the world and, in conjunction with other factors, has seriously altered the ecological dynamics of high-diversity ecosystems such as coral reefs.
