A study on the human impact on the permanent destruction of earth

The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the scheme. An irrigation scheme often draws water from the river and distributes it over the irrigated area. As a hydrological result it is found that:

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.

Environmental Statistics

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.

Humans greatly impact the world around them, and our actions can and often do have dramatic and long-lasting consequences. However, pollution contributes additional risk factors that can increase the level of destruction. The effects may be minor, such as a blackening of the surface of monuments due to dust.

Human activity is causing environmental degradation, which is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution.
