Chapter 1: what is biodiversity?

Biodiversity is the amount of difference of life. This can refer to inborn difference, species dissimilarity, or ecosystem dissimilarity within an area, biome, or plant. Global biodiversity usually highest at low latitudes near the equator, which appears to be the result of the warm climate and high main assembly. Aquatic biodiversity tends to be the most along coasts in the Western Pacific, where sea surface temperature is the most and in mid-latitudinal band in all oceans. Biodiversity commonly tends to cluster in hotspots, and has been growing through time but will be expected to slow in the future.
Fast environmental changes typically cause mass extinctions. One guess is that 1%-3% of the species that have existed on Earth are still alive today
Since life began on Earth, five major mass extinctions and several minor events have directed to huge and quick drops in biodiversity. The Phanerozoic eon (the last 540 million years) marked a speedy growth in biodiversity via the Cambrian explosion—a period during which the common species of multicellular phyla first appeared. The next 400 million years involved frequent, colossal biodiversity losses classified as extinction events. In the Carboniferous, rainforest led to a excessive loss of plant and animal life. The Permian-Triassic extinction event, 251 million years ago, was the worst; vertebrate retrieval took 30 million years. The most recent, the Cretaceous-Palaeogene…
