Essay: Revival of Extinct Species | SchoolWorkHelper
It is not a secret that the ecological situation on our planet is rather complicated.

At the moment, we are witnessing the sixth mass extinction of species. During the first of them, the majority of the marine invertebrates, as well as a huge number of terrestrial plants and insects disappeared; the second one mostly affected the dinosaurs. Even in a relatively not-so-distant past, some animal species had gone extinct completely: about 11 thousand years ago, during the Pleistocene-Holocene period, about terrestrial species died out, including mammoths, saber tooth tigers, rhinos, essay on extinct species, and some birds NCBI.
Currently, there are 14, essay on extinct species, to 35, essay on extinct species, endangered species only in essay on extinct species United States; 16, species worldwide stand on the edge of dead-end human-caused extinction, and in order essay on extinct species save them, a significant amount of effort should be made.

Throughout the last five centuries, about 1, species of all possible sizes and shapes have gone completely extinct: huge mammals such as woodland bison of West Virginia and Arizona, US: passenger pigeons and Culebra parrots; Rocky Mountain grasshoppers, and so on. And this is just those of them that we can see relatively easy; it is probably impossible to calculate how many kinds of microorganisms disappear every day before scientists even get a chance to discover and study them.
The size does not matter for nature: the tiniest organism is as important for the ecosystem as the largest of mammals Center for Biological Diversity. The good news is that it is in fact possible to not only slow down extinction, but to save some species from the danger of vanishing. In the early s, there was a program of reintroducing captive-born condors to their natural environment in California, Arizona, and northern Mexico. For example, gray wolves, who were almost completely killed during hunting across the whole North America by the end of s, are now a relatively prosperous species counting around 3, specimen, essay on extinct species. Northern elephant seals are nowadays essay on extinct species aroundalong the West Coast, although there were fewer than a hundred of them left alive just recently.

Ecologists at the University of California, essay on extinct species, Santa Barbara, believe the two species that would be especially reasonable to resurrect are the woolly mammoth, the last of which died about years ago, and the passenger pigeon, a gray bird with a red breast, once common all over North America and, which had gone extinct in early s.
Both of these species were functionally unique species strongly affecting their environments, so their vanishing had changed the ecosystems they lived in as well. In their turn, the passenger pigeons were extremely important for the forests they lived in as well ScienceMag. Reviving these two species will likely solve a number of ecological problems in an effective and quick way. As it can be see, mass extinction is not something that had never happened before on Earth. There are ways, however, to slow down or even turn back the processes of extinction; one of them, the more traditional one, is the reintroduction of cage-bred species to their natural environments.
The other more advanced one involves the most recent advancements in genetics, and will probably allow scientists to resurrect animals believed to have gone extinct forever.
