Try to cover each of the areas of the EF: Cropland & Footprint. Explain how the EF is used to estimate the demands that human populations place on the environment. To what extent are solutions directed at preventing environmental impacts, limiting the extent of the environmental impacts, or restoring systems likely to be most successful in the management of pollution?

But equally significant is the fact that some of our personal and collective choices have an enormous impact on the way human beings interact in cooperative and competitive modes, including the increasingly global search for renewable and non-renewal resources and global efforts to extract benefits from distant locations and in the process limit the extent of environmental degradation. By examining carefully the requirements of a given species and the resources available, it might be possible to estimate the carrying capacity of that environment for the species. Gravity. Try to use a mixture of data, picture evidence, maps, charts and graphs. Teaching Carrying Capacity: The Why and How. Why are some carrying capacities larger than others?

Bio-productive land: land used for food and materials, Bio-productive sea: sea area used for human consumption, Energy land: land required to support renewable energy instead of non-renewable energy, Built land: land that is used for development of roads and buildings, Biodiversity land: land required to support non-human species. the land or water required to provide and aquatic and atmospheric resources, land or water needed to assimilate wastes other than carbon dioxide, land used to produce materials imported into the country to subsidize arable land and increase yields, replacement of productive land lost through urbanization, Evaluate the link between the EF and EVS/lifestyle choices., A person who walks or takes public transportation has a smaller footprint than someone who commutes alone fifty miles to and from work in a car (especially if that car only gets 15 miles to the gallon), A vegetarian has a smaller footprint than someone who eats a lot of meat. The carrying capacity of our planet for humans is unknown; it is argued by some that we have exceeded our capacity and the numbers will eventually “die back”, while an alternative viewpoint is that advancements in technology will continue to raise our capacity, allowing the … Carrying capacity is the maximum population size that the environment can support without deterioration (McGraw-Hill, 2002). Such analyses identify which areas are placing the greatest strains on ecosystems, and can help set policy priorities. More. Website of Visions of Humanity * indicates a Case Study. This is problematic in the case of human populations for a number of reasons. Discuss why it is difficult to apply the concept of carrying capacity to human populations. Conventional Economists – trade … Explain how carrying capacity can be calculated for non-human species. One of the consequences of this explosive growth in human numbers is that human demands have outrun the carrying capacity of the economy’s natural support systems — its forests, fisheries, grasslands, aquifers, and soils. What are your views on how best to reduce carrying capacities? The EF is a model that makes it possible to determine whether human populations are living withing carrying capacity. Carrying capacity is the maximum number of a species, or “load”, that can be sustainably supported by a given area. Test. Definition. How do environmental value systems influenced carrying capacities? Today Hank is here to tell us the specifics of why and how human population growth has happened over the past hundred and fifty years or so, and how those specifics relate to ecology. Growth in animal products and energy use, especially of fossil fuels, are two areas that are rapidly increasing these strains.
