Natural Resource Depletion and the Changing Geopolitical Landscape. From competition among hunter-gatherers for wild game to imperialist wars over precious minerals, resource wars have been fought throughout history; today, however, the competition appears set to enter a new—and perhaps unprecedented—phase. As natural resources deplete, and as the Earth’s climate becomes less stable, the world’s nations will likely compete ever more desperately for access to fossil fuels, minerals, agricultural land, and water. Nations need increasing amounts of energy and raw materials to produce economic growth, but the costs of supplying new increments of energy and materials are burgeoning. In many cases, lower-quality resources with high extraction costs are all that remain.

Securing access to these resources often requires military expenditures as well. Meanwhile the struggle for the control of resources is re-aligning political power balances throughout the world. America’s Resource Geopolitics The Global Geopolitical Resource Landscape By. Join the discussion. Resource Depletion. You are in: Future Challenges : Resource Depletion Resource Depletion Sustained economic development is impossible within an effectively closed system like Planet Earth. It is therefore more than a little surprising how much attention today is being focused on climate change and yet how little is being directed toward the potentially far more pressing issue of resource depletion.

Fortunately these two challenges are inter-linked to the extent that most measures intended to combat climate change do involve using less resources and/or recycling precious materials. It cannot now reasonably be denied that the Earth's natural resources are currently being consumed at an increasing and totally unsustainable level. In 2011 the United Nations Environment Programme reported that, if nothing changes, humanity will demand 140 billion tons of minerals, ores, fossil fuels and biomass every year by 2050. Coping most successfully with resource depletion will requires a broad range of strategies.

Resource depletion. Water Water is critical to all life. Too much or too little clean water can have enormous negative impacts. Water quality and conservation are acute issues that must be addressed. Water quality Water pollution is the loss of water use caused by a change in it’s composition due to human activity. The three major sources of water pollution are municipal, industrial and agricultural. More people on the planet lead to more: SewerageStock effluentFertilisers, herbicides and pesticides used for crops, lawns and parksFossil fuels extracted and burnedOil leaked and spilledLand deforested and developedVarious byproducts of manufacturing and shipping The hydrological cycle is the cycle where water evaporates from the sea and is precipitated on land – rain, hail and snow – and is stored in the ground as groundwater (which is ultimately discharged into waterways) or if it cannot be absorbed it returns to the sea through run-off.

Fossil fuels Unfortunately, we are not reducing our dependence on coal. Adjusted savings: natural resources depletion (% of GNI) Natural Resources: Depletion Reasons, Types and their Conservation. All the materials and energy essential for the survival and welfare of living beings including humans-are provided by nature. They are called natural resources. A thing becomes resource only when it is used by humans to perform a function. Man lives in nature and depends on the resources of nature. The sustenance and welfare of mankind depend upon the exploitation of different natural resources.

The utilization of soil, water minerals, coal, electricity, oil, gas and nuclear energy is very important for the development of nation These resources have changed the level of living standard of man. Of the world’s total population of six billion, one billion in U.S.A. and Europe alone use 84% of world’s total energy. Three billion people of India, China, Brazil and few other countries use only 15% India contains the world’s second largest resource of coal and third and four largest resource of manganese and iron. Consequently, some natural stocks of plants and animals have disappeared. 1. 2.

Natural resource depletion emerges as dominant environmental concern in global North - @GlobeScan Blog. The depletion of natural resources has emerged as the dominant environmental concern among citizens of the global North, according to the latest wave of GlobeScan's tracking survey of world environmental concerns, rating ahead of issues such as climate change and water shortages. Environmental concern has been on a long-term upward trajectory, with majorities of the global public in countries tracked by GlobeScan rating a range of environmental challenges as “very serious,” despite a falling back of concern, particularly about the climate, in 2009.

The map above illustrates the degree to which regional dynamics and economic circumstances influence the perceived severity of environmental issues around the world. Water shortages are the dominant public concern in sub-Saharan Africa, air pollution and species loss in Latin America, and automobile emissions in rapidly urbanizing China. Climate change remains a second-tier environmental concern in most nations. The six natural resources most drained by our 7 billion people | Environment.

With 7 billion people on the planet – theoretically from today – there will be an inevitable increase in the demand on the world's natural resources. Here are six already under severe pressure from current rates of consumption: 1. Water Freshwater only makes 2.5% of the total volume of the world's water, which is about 35 million km3. 2. The fear of reaching peak oil continues to haunt the oil industry. 3. A similar picture to oil exists for natural gas, with enough gas in proven reserves to meet 58.6 years of global production at the end of 2010. 4.

Without this element, plants cannot grow. 5. This has the largest reserves left of all the fossil fuels, but as China and other developing countries continue to increase their appetite for coal, demand could finally outstrip supply. 6. Scandium and terbium are just two of the 17 rare earth minerals that are used in everything from the powerful magnets in wind turbines to the electronic circuits in smartphones. Resource depletion: Opportunity or looming catastrophe? Image copyright AP Imagine a world of spiralling food prices, water shortages and soaring energy costs. For many living in the world today, this nightmare scenario is already a reality. Even for the well-off living in developed economies, it's becoming all too familiar. And on current projections, it's going to get a whole lot worse. Short-term fluctuations in supply and demand aside, a global population explosion combined with finite resources means the planet cannot sustain ever-increasing levels of consumption using current models of production.

And there isn't much time to do something about it. "The challenge we are facing over the next 20 years is unprecedented," says Fraser Thompson, senior fellow at the McKinsey Global Institute. Exploding population The reasons for such price falls were simple - the discovery of new sources of relatively cheap supply allied with new technologies. But the era of abundant cheap resources is drawing to an end, for reasons equally straightforward. Global Resource Depletion: Is Population the Problem? Fred Magdoff is professor emeritus of plant and soil science at the University of Vermont.

He is coauthor with John Bellamy Foster of What Every Environmentalist Needs to Know About Capitalism (Monthly Review Press, 2011). Environmentalists and scientists often refer to the two different ends of the environmental problem as sources and sinks. Thus the environmental limits to economic growth manifest themselves as either: (1) shortages in the “sources” or “taps” of raw materials/natural resources, and thus a problem of depletion, or (2) as a lack of sufficient “sinks,” to absorb wastes from industrial pollution, which “overflow” and cause harm to the environment. The original 1972 Limits to Growth study emphasized the problem of sources in the form of shortages of raw materials, such as fossil fuels, basic minerals, topsoil, freshwater, and forests.

The following analysis will address the environmental problem from the source or tap end, and its relation to population growth. Chart 1. Consequences of Depletion of Natural Resources - The World Counts. TheWorldCounts, 22 March, 2014 Are we using up more than what is available? Our current global population is 7.2 billion and growing. (1) Earth’s total resources are only good for 2 billion people at the current demand. Let’s do the math, and it is obvious that the result is a negative. The way we’re living, we are already using 2 to 3 times more of the Earth’s natural resources than what is sustainable.

If we do not act now, we will see the consequences of depletion of natural resources – and it’s not going to be pretty. Our Natural Resources are running out What are the top 3 natural resources being depleted and what are the consequences? 1. What will we drink without water? Only 2.5% of the world’s total water volume is fresh water. Causes: Increased irrigation, increased use in agriculture, roads and infrastructure prevent water seepage in the soil, rising temperatures Consequences: Drinking water shortage. 2. Causes: Industrial boom. Consequences: Less Transportation. 3. References. Environmental Impacts of Renewable Energy Technologies. All energy sources have some impact on our environment.

Fossil fuels — coal, oil, and natural gas — do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions. Learn more: The Benefits of Renewable Energy Use It is still important, however, to understand the environmental impacts associated with producing power from renewable sources such as wind, solar, geothermal, biomass, and hydropower. The exact type and intensity of environmental impacts varies depending on the specific technology used, the geographic location, and a number of other factors. Wind Power Harnessing power from the wind is one of the cleanest and most sustainable ways to generate electricity as it produces no toxic pollution or global warming emissions.
