what percent of life was killed in the triassic extinction? end-Triassic extinction, also called Triassic-Jurassic extinction, global extinction event occurring at the end of the Triassic Period (about 252 million to 201 million years ago) that resulted in the demise of some 76 percent of all marine and terrestrial species and about 20 percent of all taxonomic families.
What is the impact of extinction on humans? Well, according to new research published December 2 in Nature, the answer is yes—healthy biodiversity is essential to human health. As species disappear, infectious diseases rise in humans and throughout the animal kingdom, so extinctions directly affect our health and chances for survival as a species.
What causes extinction and what are its impacts? The single biggest cause of extinction today is habitat loss. Agriculture, forestry, mining, and urbanization have disturbed or destroyed more than half of Earth’s land area. In the U.S., for example, more than 99 percent of tall-grass prairies have been lost.
