Biodiversity growth and extinction

About 30, species go extinct annually. There is little doubt left in the minds of professional biologists that Earth is currently faced with a mounting loss of species that threatens to rival the five great mass extinctions of the geological past. As long ago asHarvard biologist E. Wilson estimated that Earth is currently losing something on the order of 30, species per year — which breaks down to the even more daunting statistic of some three species per hour.

Back to top Long Term Costs If ecosystems deteriorates to an unsustainable level, then the problems resulting can be very expensive, economically, to reverse. In Bangladesh and India, for example, logging of trees and forests means that the floods during the monsoon seasons can be very deadly.

Similarly, many avalanches, and mud slides in many regions around the world that have claimed many lives, may have been made worse by the clearing of so many forests, which provide a natural barrier, that can take the brunt of such forces.

As the Centre for Science and Environment mentions, factors such as climate change and environmental degradation can impact regions more so, and make the impacts of severe weather systems even worse than they already are.

As they further point out, for poor regions, such as Orissa in India, this is even more of a problem.

1 What is biodiversity?

Vanishing coral reefsforests and other ecosystems can all take their toll and even make the effects of some natural events even worse. The cost of the effects together with the related problems that can arise like disease, and other illness, or rebuilding and so on is much more costly than the maintenance and sustainable development practices that could be used instead.

As an example, and assuming a somewhat alarmist scenario, if enough trees and forests and related ecosystems vanish or deteriorate sufficiently: Then the oxygen-producing benefits from such ecosystems is threatened.

The atmosphere would suffer from more pollution. The cost to tackle this and the related illnesses, problems and other cascading effects would be enormous as it can be assumed that industrial pollution could increase, with less natural ecosystems to soak it up Furthermore, other species in that ecosystem that would depend on this would be further at risk as well, which would lead to a downward spiral for that ecosystem.

Compare those costs to taking precautionary measures such as protecting forests and promoting more sustainable forms of development. Of course, people will argue that these situations will not occur for whatever reasons. Only when it is too late can others say told you so — a perhaps very nasty Catch The Economics of Ecosystems and Biodiversity TEEB is an organization — backed by the UN and various European governments — attempting to compile, build and make a compelling economics case for the conservation of ecosystems and biodiversity.

It has also attempted to put a value on the ecological services provided to humanity. From a cost perspective p. What the global economy would look like with nature on the balance sheet What is the world worth?

Take for example the various indigenous Indians of Latin America. Throughout the region, as aspects of corporate globalization spread, there is growing conflict between land and resources of the indigenous communities, and those required to meet globalization related needs.

The following quote from a report on this issue captures this quite well: Many of the natural resources found on Indian lands have become more valuable in the context of the modern global economy.The variety of life on Earth, its biological diversity is commonly referred to as biodiversity.

The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. The Global Education Project - Global Ecology: Climate change, Ocean currents, Biodiversity, Deforestation, Extinctions.

FAO’s corporate booklet on Biodiversity. Biodiversity is the variety of plant and animal life in the world, including their genetic diversity and the variety of species and ecosystems.

Biodiversity — Global Issues

Human population growth and overconsumption are at the root of our most pressing environmental issues, including the species extinction crisis, habitat loss and climate change. article highlights. Can we stop the devastation of our planet and save our own species? We are in a biodiversity crisis — the fastest mass extinction in Earth’s history, largely due to.

Compared to other threats to biodiversity, invasive introduced species rank second only to habitat destruction, such as forest clearing.

Of all 1, imperiled species in the United States, 49% are endangered because of introduced species alone or because of their impact combined with other forces.
