The new assessment is based on models projecting the extent and pattern of deforestation across the Amazon. Of particular concern are species with longer life spans, such as Rio Branco Antbird Cercomacra carbonariafor which even moderate rates of deforestation can be important. Intensive conservation action, particularly through control of alien invasive predators like black rats, has saved the species from extinction.
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.
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. Several factors have spurred renewed interest in natural resources on Indian lands in Latin America, among them the mobility of capital, ecological limits to growth in developed countries, lax environmental restrictions in underdeveloped nations, lower transportation costs, advances in biotechnology, cheap third world labor, and national privatization policies.
Limits to logging in developed countries have led timber transnationals overseas. Increased demand and higher prices for minerals have generated the reopening of mines and the proliferation of small-scale mining operations. Rivers are coveted for their hydroelectric potential, and bioprospecting has put a price tag on biodiversity.
Originally considered lands unsuitable for productive activities, the resources on Indian lands are currently the resources of the future.
Indian land rights and decisionmaking authority regarding natural resource use on territories to which they hold claim threaten the mobility of capital and access to resources—key elements of the transnational-led globalization model.
Accordingly, increased globalization has generally sharpened national conservative opposition to indigenous rights in the Americas and elsewhere in the name of making the world safe for investment.
The World Trade Organization WTOfree trade agreements, and transnational corporations are openly hostile to any legislation that might create barriers to investment or the unlimited exploitation of natural resources on Indian lands.
The result has been a growing number of conflicts between indigenous communities and governments and transnational corporations over control of natural resources. Back to top The Military and the Environment Many military forces of the world also have an effect on the environment.
Sometimes, the scale of problems they leave when they move out of a training area or conflict is considerable. In some nations, such as the United States, the military can be exempt from many environmental regulations.
By no means a complete set of examples, the following illustrate some of the issues: The effects are still being felt. In the Democratic Republic of Congovarious forces often kill gorillas and other animals as they encroach upon their land.Orangutans need the rainforests to survive and so do we As well as being the greatest threat facing orangutans, deforestation harms people’s lives and livelihoods in Sumatra and around the world.
Water covers 70% of our planet, and it is easy to think that it will always be plentiful. However, freshwater—the stuff we drink, bathe in, irrigate our farm fields with—is incredibly rare.
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. An endangered species is a type of organism that is threatened by extinction.

Threatened & Endangered Species In the past, most extinctions were due to natural causes. In fact, extinction is a naturally occurring phenomenon that occurs at a rate of roughly one to five species each year; however, scientists currently believe that habitats across the globe are now losing dozens of species each day.
