The world has an amazingly diverse number of different species of animal and plant life, but many are in danger of being lost for ever, often as a result of human action an endangered species is a group of organisms which is at risk of becoming extinct. The extinction crisis it's frightening but true: our planet is now in the midst of its sixth mass extinction of plants and animals — the sixth wave of extinctions in the past half-billion years we're currently experiencing the worst spate of species die-offs since the loss of the dinosaurs 65 million years ago although. What also makes this a problem is that many of the endangered species are only found in small areas of land, often within the borders of a single country new species of animals and plants are still being discovered in papua new guinea, 44 new species of. No longer having food to eat, the sea urchins populations became locally extinct as well finally since kelp forest ecosystems are homes to many other species, the loss of the kelp ultimately caused their extinction as well we are not sure what will happen when the tigers die in our tropical forests what will happen if the. Recently in geological time, humans have become an additional cause of extinction (many people would say premature extinction) of some species, either as a new mega-predator or by transporting animals and plants from one part of the world to another such introductions have been occurring for thousands of years,. Over the same period, as many as 26 species (either listed in iucn list or under review to be listed) became extinct  such an unaffordable level of extinction calls for an in-depth study of the conservation strategies and plans as a first step, it is necessary to study the basic principles on which these efforts were designed. Current evidence suggests that few marine organisms have become globally extinct in the past 300 years, where 829 species have disappeared however, there is little precise information regarding how many species are being extinguished in the marine environment. And to get around the problem of under-reporting, she threw away the iucn's rigorous methodology and relied instead on expert assessments of the likelihood of extinction thus, she figured that amastra baldwiniana, a land snail endemic to the hawaiian island of maui, was no more because its habitat.
Flight ways differs from many other books in that it's less interested in the phenomenon itself than in our moral and emotional responses to the crisis i have a background in philosophy and anthropology so i'm more interested in how we understand and live with extinction i started out wanting to write a.

Another factor in conservation policy has been the type of species facing extinction many conservation efforts have highlighted endangered mammals and birds while ignoring smaller and less visible reptiles and amphibians the southeastern us, for instance, is home to a wide variety of salamanders. Moreover, ecologists can never even know if extinction rate estimates are borne out it will not be possible to determine at a future date the number of species that went extinct between now and that future date without knowledge of how many species exist today the serious problems associated with extinction rate.
Mobile apps, gis satellite data, and online crowdsourcing, pimm says, may be a partial antidote to the problem through these technologies pimm says conservationists can calculate the extinction rate of the known species by keeping track of how many die out each year the technique is similar to that. In addition to the problems arising from using collections data and ecoregions, we based our estimates of extinction probabilities on changes in habitat area predicted over the next several decades (which itself may be erroneous, especially for areas outside the brazilian amazon for which overall. At this historic moment, however, as at past historical moments, the problems of extinction animals don't lose its relevance to biological diversity of the earth has suffered irreparable damage, and further reduce the number of species of animals and plants continues the research teams of many countries study objective.
Scientists predict we're on the verge of the sixth mass extinction many scientists feel human activity is causing increased extinction rates an individual human being can raise consciousness of what is happening to animal species across the planet, helping people to realize how extensive the problem of extinction is.
Numerous examples of workable solutions to local problems are available/1 5 species and natural ecosystems make many important contributions to human welfare 2 although most of these studies are generalized in their documentation and few offer lists of individual species at risk or recently extinct, some present.
