Unit 1 The Challenge of Sustainable Development

The climate crisis is accelerating at an unprecedented rate, and we are not ready for it. While the crisis has many factors that play a role in its exacerbation, there are some that warrant more attention than others. Here are some of the biggest environmental problems of our lifetime. According to economists like Nicholas Stern, the climate crisis is a result of multiple market failures. Economists and environmentalists have urged policymakers for years to increase the price of activities that emit greenhouse gases one of our biggest environmental problems , the lack of which constitutes the largest market failure, for example through carbon taxes, which will stimulate innovations in low-carbon technologies. To cut emissions quickly and effectively enough, governments must not only massively increase funding for green innovation to bring down the costs of low-carbon energy sources, but they also need to adopt a range of other policies that address each of the other market failures.

Global Environmental Change and the International Efforts Concerning Environmental Conservation

Yet its capacity to provide for each one of these individuals is threatened by population growth, climate change, deforestation, collapse of fisheries, desertification, air pollution and scarcity of fresh water. The full extent of our shared global environmental problems goes far beyond the well-publicised challenge of global climate change or global warming. In fact, one of the elements often forgotten is the complicated relationship between human beings and their environment. However, there are limits to growth and this raises a range of important issues for international relations.

Global Environmental Issues and Human Wellbeing

June 1, David Hunter. In the past three decades, protecting the global environment has emerged as one of the major challenges in international relations. No fewer than ten global environmental treaties have been negotiated as well as literally hundreds of regional and bilateral agreements. Governments have also endorsed dozens of comprehensive action plans, most notably the page Agenda 21, which set forth a blueprint for implementing sustainable development.

Global environmental problems involve one or more of the following:. Rapid Population Growth. Food Production and Equitable Distribution. Global Warming.

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. This coming decade will be vital when it comes to solving the big environmental issues facing our planet. The third decade of the 21st century has begun and the environmental challenges we have ahead of us, set out in the UN's Agenda for Sustainable Development, are many. This global plan of action adopted in puts forward specific measures to achieve a world that is fairer, more prosperous and more respectful of the environment within ten years.

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. It is the main driver behind rising humanitarian needs and we are seeing its impact. The number of people affected and the damages inflicted by extreme weather has been unprecedented. Environment destruction caused by humans is a global, ongoing problem.

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.

Report on Global Environmental Competitiveness pp Cite as. Environment is the foundation and support of human existence and survival and the guarantee of sustainable human development; environmental protection has undoubtedly become a common understanding and development strategy of all countries of the world. Now humankind is striving into the historical process of postindustrial society and is trying to reach rebalance with environment in later stage of development. All countries need to perform respective duties and obligations in environment governance, in joint efforts to plan economic development, social progresses and environment protection to realize mutual wins and sustainable development of the world and to create an Earth homeland for harmonious co-existence of humankind and environment. Ozone depletion and destruction is caused by ozone-depleting substances, mainly chlorofluorocarbons CFCs.

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.

For years now, humans have mistreated and contaminated the very environment that sustains them.
