Us must commit to sustainability to overcome mounting economic and ecological strains worldwatch report assesses us sustainability record and calls for renewed innovation and leadership. More on population growth, ecological footprint, equity: when population growth and resource availability collide connecting the dots: population growth, consumerism & biodiversity loss tangled.
The same one-two punch of population growth followed by consumption growth is now occurring in china (134 billion people) and india (12 billion. The united states is an ecological debtor, consuming some 207 percent of its ecological capacity, according to the global footprint network it ranks as the 46th greatest ecological debtor worldwide out of 151 countries evaluated.
Sustainable population levels in order to assist the deficit nations with their deficits until the surplus nation achieves its population balance level growth, footprint & the human condition providing capacity to other nations implies reducing one's own nation's sustainable population level and footprint —and continual declines in. In recognition of the fact that issues of human population growth are fundamental to sustainability, the original sustainable biosphere initiative report featured a segment on human population growth which stated that to more fully understand how human populations affect and are affected by ecological processes, the complex interfaces between. On the demand side, the ecological footprint measures the ecological assets that a given population requires to produce the natural resources it consumes (including plant-based food and fiber products, livestock and fish products, timber and other forest products, space for urban infrastructure) and to absorb its waste, especially carbon emissions. The footprint deficit and population departure seen in table 1, column d, assesses the degree a nation exceeds its ecological capacities, ie, rising risk, as a nation moves away from its sustainable balance point.
(305) despite the increased popularity of the use of the term sustainability, the possibility that human societies will achieve environmental sustainability has been, and continues to be, questioned—in light of environmental degradation, climate change, overconsumption, population growth and societies' pursuit of unlimited economic growth in a closed system. Sustainability my ecological footprint: after taking my ecological footprint quiz, it seems that to support the lifestyle i’m living, it takes 34 hectares of the earth’s productive area and it requires the regenerative capacity of 19 planets each year.
Current population is three times the sustainable level global footprint network data shows that humanity uses the equivalent of 17 planet earths to provide the renewable resources we use and absorb our waste 1 if all 7+ billion of us were to enjoy a european standard of living - which is about 60% the consumption of the average american - the earth could sustainably support only about 2 billion people.

Population growth and the ecological balance geo 702: technology and contemporary environment professor valentina capurri student name zohra mohammad student number 500 383 844 submission date 05/11/2014 with the rapid growth of population in various areas of the world, the global leaders have taken a moment to realize the consequences and the impact this is having on the ecological balance of the earth.
Slower population growth that leads to eight billion people in 2050 rather than to the currently projected 91 billion would save one billion to two billion tons of carbon annually by 2050, according to estimates by climate scientist brian o’neill of the national center for atmospheric research and his colleagues. William rees, also of the university of british columbia, introduced the concept of the ecological footprint, or the amount of land needed to sustain a population and its consumptive habits, contending that if the current consumption rates of industrial countries were to spread to lesser developed nations, an area equivalent to two extra planets would be needed to sustain human life.
