Physical water scarcity prevails in those regions where surface and groundwater resources are inadequate to supply the region's water demands.
physical and economic
Physical water scarcity occurs when and where there is not enough water to meet both human demands and those of ecosystems to function effectively. Arid regions frequently suffer from physical water scarcity. It also occurs where water seems abundant but resources are over-committed.
Economic water scarcity is caused by a lack of investment in water infrastructure or insufficient human capacity to satisfy the demand of water in areas where the population cannot afford to use an adequate source of water.

What industry is agriculture ?
agriculture is thecultivation of land and breeding of animals and plants to provide food, fiber,medicinal plantsand other products to sustain and enhance life.

What is the largest part of the earth: the core,the mantle, or the crust
The answer to this question is: mantle.
the crust due to the fact that is has a larger circumference
Describe how ocean currents help make temperatures at different places on earths surface more similar than they would be if there were no currents
The earths surface is heated by the Sun's rays which are directed at the equator 0° latitude. If there were sea currents the closer you got to the equator the hotter it will get and the further away you go from the equator the colder it will get. Thus ocean currents distribute the heat at the equator around the earths oceans to even out the difference in the heat zones, so that the equator is not a desert and the rest of the earth is an ice age.
resources are an integral part of human survival.yet indiscriminate use of them by humans has led to a crisis situation."discuss the above ststement in light of changes/developments.
You could challenge the premise of the question - what exactly is the crisis? It is easier to argue that humanity has actually avoided resource crises due to its continued and proven capacity for innovation. For instance, agricultural productivity expanded tremendously in the twentieth century. Whereas the majority of workers in Western societies were employed in agriculture in 1900, by 2000 that proportion was under 5%. Improved cultivation methods, the mechanization of farm implements, the tailoring of crops to specific soil types, crop rotation, improved irrigation, and the development of genetically modified crops selected for their productivity and resistance to pests have all enabled the output per person per acre to expand tremendously and support the massive global population growth seen over the past century.
How does overpopulation in South America impact global warming?
Well overpopulation puts huge dent in available food supplies. This results in deforestation to make both farmland and lumber for building to house everyone. deforestation create CO2, and depletes vegetation which would have absorbed CO2
