Document Summary
Animals that are densely concentrated in feedlots will not contribute to. However, wage from feedlots emit sting odours and can pollute. Poor waste containment practices at some feedlots have been linked. One partial solution is to feed livestock crop residues, plant matter surface water and groundwater to outbreaks of disease such as stems and stalks. Aquaculture is raising aquatic organisms in controlled environments. Dense concentrations of farmed animals can increase the incidence of disease. Sustainable agriculture is agriculture that does not deplete soils faster than they form. Soil degradation has reduced potential rate of global grain production by. Natural resources the various substances and energy sources we need to survive. Some are renewable natural resources such as wind, sun and wave; other renew themselves but can become nonrenewable if we use too much too quickly like fossil fuels and minerals. Rst started with early humans gaining control of re and stones as tools.
