Climate change is the big environmental problem that humanity will face over the next decade, but it isn't the only one. We'll take a look at some of them — from water shortages and loss of biodiversity to waste management — and discuss the challenges we have ahead of us.

Hitachi Group Corporate Information. Global environmental problems have become increasingly acute with the progress of global-scale industrialization and urbanization. The international community has begun to tackle issues that extend beyond national borders, such as global warming, resource depletion, and ecosystem destruction, with the UN playing a central role. Sustainable development over the long run requires raising environmental awareness and acting together with diverse stakeholders, but how does the Hitachi Group view global environmental problems and take them on?

ENVIRONMENTAL ISSUES

Donald A. By the year it is expected to have grown to between nine and ten billion people. During this time of dramatic population growth, the human impact on the planet has increased significantly, not only because of the huge increase in our numbers, but also because of the new technical power to dig deeper, cut faster, build larger, and traverse more quickly great distances in automobiles, trucks, and planes. As a result, serious new environmental problems have emerged on a global scale. These new threats raise critical new ethical questions for the human race. Yet even some of the most obvious ethical dimensions of emerging global environmental problems are only dimly seen by most; rarely are they part of the public debate.

Together with the widening realisation of the problem of poverty, there has been an increasing awareness of the existence of a second global crisis: that of environmental degradation. Concerns about the state of the environment have deep historical roots, but those concerns came to prominence during the s following the publication in of a seminal book by Rachel Carson, Silent Spring , and the emergence of the modern environmentalist movement in some countries Carson Since then, and particularly since the s, considerable scientific efforts have been made to investigate and to document the state of the global environment and the nature of global environmental change. Those efforts have been prompted by widespread concerns that the pace and extent of development in many parts of the world have far outstripped the capacity of natural ecosystems to absorb the impacts of human activities. Numerous environmental changes have been identified as issues of global concern: desertification; the depletion of fuelwood; the destruction of tropical rainforest and rapid declines in forest cover; the modification of coastal ecosystems; the reduced availability and quality of drinking water; the depletion of soil resources; the over-exploitation of fisheries; food shortages; species extinction and the loss of biodiversity; stratospheric ozone depletion; rapidly rising levels of fossil fuel and demand for energy supplies; and climate change.

Current Environmental Issues and Challenges

Environmental issues are harmful effects of human activity on the biophysical environment. Environmentalism , a social and environmental movement , addresses environmental issues through advocacy, education and activism. The amount of greenhouse gas in the atmosphere is possibly above the threshold that can potentially cause climate change.

One of the most compelling reasons for studying environmental science and management is the fact that, in the view of many leading authorities, we are now experiencing an environmental crisis; indeed, many authors have claimed that the present environmental crisis is unprecedented in its magnitude, pace and severity Park Awareness of this environmental crisis has grown since the s, partly as a result of the prominence given to major so-called 'environmental' disasters such as the Sahelian droughts of the s and s and the nuclear accident at Chernobyl in Consequently, a wide range of environmental problems has emerged; those problems include anthropogenic climate change 'global warming' , the depletion of stratospheric ozone the 'ozone hole' , the acidification of surface waters 'acid rain' , the destruction of tropical forests, the depletion and extinction of species, and the precipitous decline of biodiversity.

Human–Environment. Interactions. Frances Harris. Introduction. Environmental issues have been a concern for many years. Yet somehow they are problems.

By way of mapping the drivers of global environmental decline, we highlight the problems associated with devising effective management.
