Environment Science

Among the urgent issues of today`s external agenda the problems cerebrate to the protection of environment are definitely one of the just about visible ones . However , attempts to instate regulative environmental public policies at the same time create a lot of rock , because the scope of existing negative process of human performance on environment , and even the very fact of much(prenominal) influence , is often disputed . Basically , the to a greater extent(prenominal) great is the sp here(predicate) of global economics subject to regulation , the more problematic it becomes to find a consensus on the matter of execution of environmental public policies that would require immediate expenses . For example , when it was lay out that the ozone depletion was primarily due to chlorofluorocarbons (CFCs ) gases their use was phased out under international agreement However , while these gases were widely industrially apply such a relatively quick action was enabled by the introduction of avaiable substitutes for chlorofluorocarbons . Now , the problem of chlorofluorocarbons is quite petty in comparison with another human activity , namely the earnest of fossil fuels which leads to build-up of carbon dioxide in the atmosphere and which apparently has the largest influence on environment via global warming . But here the problem is much more acute as the well-nigh critical branches of global economics depend on fossil fuel , and attempts to rapidly shift to alternative technologies may thusly be very costly .

Still , I conceive that if the direct link between global warming and turn up negative environmental consequences is established , then economic do of such disasters as devastation of New Orleans by hurricane Katrina , the economic cost of which according to some estimates could reach more than 100 billion (CNN 2005 , would justify all costs of environmental programs . And those who offer public policies directed not at the etymon of the prime cause but only at the adaptation to the consiquences of environmental changes are short-sighted , as we can hardly be sure that in the future the situation will break short worsening , so a massive amount of currency will have to be constantly spent for unexampled adaptations , and any hope of achieveing global environmental sustainability will be lostReferencesKatrina could cost economy 100B .
