SAU1 Blog Post 1 : The 6th Mass Extinction
The scientists called the mass extinction that is currently taking place on Earth ''The 6th Mass Extinction'', or “The Holocene Extinction”. It is a kind of widespread and continuous extinction in Holocene, the youngest geological epoch. Most of the major extinctions are happened in the highly biodiverse habitats like rain forest and coral reefs, and there are a large number of plants and animals, such as mammals, birds, and other species were died away.
Nowadays, the human overpopulation and over-consumption cause a huge damage to our environment. Human using the chemicals like pesticides, herbicides, cutting the forests or other tings on agriculture and industry for more and more economic gain, which will lead habitat loss and climate change. Even in some parts of the world, poachers are hunting rare species for wildlife parts like rhino horn and elephant ivory. These kinds of the deed make the current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background rates.
Without a suitable habitat, species can't survive, and without various ecology, human can't exist on this planet anymore. So we can try our best to reduce the use of the chemicals and maintain the integrality of the habitats to conserve already threatened species. With the effort from all the human, maybe we can slow down or even stop the extinction.
