In this process, the plants and animals which previously used the site are displaced or destroyed, reducing biodiversity. Habitat destruction by human activity is mainly for the purpose of harvesting natural resources for industry production and urbanization.
Human beings are currently causing the greatest mass extinction of species since the extinction of the dinosaurs 65 million years ago.
If present trends continue one half of all species of life on earth will be extinct in less than years, as a result of habitat destruction, pollution, invasive species, and climate change. For details see links below. This website began on April 22, with the posting of the article below.
The article is still here to provide historical context. Following the article are more than links to recent authoritative reports and updates about the current mass extinction.
New articles are added regularly. Most recent update September 17, Although scientists are divided over the specific numbers, many believe that the rate of loss is greater now than at any time in history.
Nearly seven out of 10 of the biologists polled said they believed a "mass extinction" was underway, and an equal number predicted that up to one-fifth of all living species could disappear within 30 years.
Nearly all attributed the losses to human activity, especially the destruction of plant and animal habitats. Among the dissenters, some argue that there is not yet enough data to support the view that a mass extinction is occurring.

Many of the estimates of species loss are extrapolations based on the global destruction of rain forests and other rich habitats.
Among non-scientists, meanwhile, the subject appears to have made relatively little impression.
Sixty percent of the laymen polled professed little or no familiarity with the concept of biological diversity, and barely half ranked species loss as a "major threat.

Desertification, deforestation, and coral reef degradation are specific types of habitat destruction for those areas (deserts, forests, coral reefs). UN News produces daily news content in Arabic, Chinese, English, French, Kiswahili, Portuguese, Russian and Spanish, and weekly programmes in Hindi, Urdu and Bangla.
Our multimedia service, through this new integrated single platform, updates throughout the day, in text, audio and video – also making use of quality images and other media from across the UN system.
Climate change is also wreaking havoc with habitats around the world. Some, like the Arctic coastal lands, are thawing and sea ice is simply disappearing. Other habitat types are shifting, affecting migration patterns and altering where wildlife can find food, shelter, and potential mates.
I. Introduction Because feral cat colonies are of great concern to communities where they reside, and especially because of their potential to dramatically alter the makeup of ecosystems through predation, the question of who is legally responsible for these animals must be addressed.
FREQUENTLY ASKED QUESTIONS ABOUT CROWS. Note: Most of these answers pertain to the American Crow, Corvus benjaminpohle.com of the information here is from my own research on crows in central New York; where I used other sources I have tried to reference the benjaminpohle.com Pollution, disease, and limited distribution are additional factors which threaten plants and animals with extinction.
A species without the natural genetic protection against a particular pathogen can be terminally affected by an introduced disease.
