Population stabilization and resource conservation will lead to the challenges of sustainability. As the century begins, natural resources are under increasing pressure, threatening public health and development. Water shortages, soil exhaustion, loss of forests, air and water pollution, and degradation of coastlines afflict many areas.
Most developed economies currently consume resources much faster than they can regenerate. Most developing countries with rapid population growth face the urgent need to improve living standards.
As we humans exploit nature to meet present needs, are we destroying resources needed for the future? Environment getting worse About 3 million die from pollution each year. In the past decade in every environmental sector, conditions have either failed to improve, or they are worsening: Unclean water, along with poor sanitation, kills over 12 million people each year, most Environment and population developing countries.
Air pollution kills nearly 3 million more. Heavy metals and other contaminants also cause widespread health problems.
Will there be enough food to go around? In 64 of developing countries studied by the UN Food and Agriculture Organization, the population has been growing faster than food supplies.
Population pressures have degraded some 2 billion hectares of arable land — an area the size of Canada and the U. The supply of freshwater is finite, but demand is soaring as population grows and use per capita rises. Bywhen world population is projected to be 8 billion, 48 countries containing 3 billion people will face shortages.
Half of all coastal ecosystems are pressured by high population densities and urban development. Ocean fisheries are being overexploited, and fish catches are down. Yet human activities are pushing many thousands of plant and animal species into extinction.
Two of every three species is estimated to be in decline. If the global temperature rises as projected, sea levels would rise by several meters, causing widespread flooding. Global warming also could cause droughts and disrupt agriculture.
Toward a livable future How people preserve or abuse the environment could largely determine whether living standards improve or deteriorate. Growing human numbers, urban expansion, and resource exploitation do not bode well for the future.
Without practicing sustainable development, humanity faces a deteriorating environment and may even invite ecological disaster. Many steps toward sustainability can be taken today. While population growth has slowed, the absolute number of people continues to increase — by about 1 billion every 13 years.
Slowing population growth would help improve living standards and would buy time to protect natural resources. In the long run, to sustain higher living standards, world population size must stabilize. Less growth will provide time to solve sustainability problems. Population and sustainable development Environmentalists and economists increasingly agree that efforts to protect the environment and to achieve better living standards can be closely linked and are mutually reinforcing.The link between population growth and the environment is found somewhere between the view that population growth is solely responsible for all environmental ills and the view that more people means the development of new technologies to overcome any environmental problems.
Population and Environment is a peer-reviewed academic journal covering research on the bi-directional links between population, natural resources, and the natural environment. The editor-in-chief is Dr Elizabeth Fussell, associate professor of population studies and . Environment.
Humanity relies on ecosystems and biodiversity for its well-being in many acknowledged and some unacknowledged ways.
Yet we are systematically reducing the quantity and variety of the natural world through development, pollution — including climate change — and resource exploitation. The interactions between human population dynamics and the environment have often been viewed mechanistically.
This review elucidates the complexities and contextual specificities of population-environment relationships in a number of domains. Population and Environment is aimed at researchers working in academic and policy institutions in the fields of demography, economics, sociology, geography, environmental studies, public health, ecology and associated sub-disciplines.
Population and Environment "The nation’s ongoing debate over immigration generally has not focused on the effect it has on U.S. population size. Yet, increasing the nation’s total population is one of immigration’s clearest and most direct effects.
