  Resource Use
  
  
  Part One
  
  Agriculture
  
  a)     Five environmental concerns associated with agriculture are risks of agricultural production also vary significantly as a function of the type of production, the environment in which production takes place, and management practices. Environmental issues related to agriculture and agri-food production include water quality and use; use and management of agricultural inputs (nutrient, pesticides and energy); land use, land management, and soil quality; climate; and air quality. Water quality, now the public's greatest concern related to natural resources, is affected by management of soils, manure, fertilizers, pesticides, and other chemicals.
  
  b)     The environmental future of Canadian agriculture will continue to be shaped by social and economic forces, including the world's demand for food; commodity prices; federal, provincial and municipal government policies; international trade agreements; technology; and agricultural research. Primary production agriculture will need to increase production on existing crop land to meet the growing world demand for food and non- food products. This will likely mean continued intensification and concentration of production in both crop and livestock commodity sectors, and potentially increased environmental risks.
  
  c)     One region in the world challenged by the continued use of agriculture is Johannesburg, South Africa. There aren't any good farming soils there to grow anything and with the heat they deal with, it is going to dry up the fields quickly. Also the water is limited and any water they get is going to be very poor and ineffective.
  
  
  Part Two
  
  Tidal
  
  
  
  a)     Three advantages associated with the use of tidal are:
             -Water is a free resource
             - No pollution
             - It produces no greenhouse gases or other waste
  
  b)     Three disadvantages associated with the use of tidal are:
        - Not yet economically feasible
        - Problems with transportation of hydroelectricity
        - Technology not developed
  
  c)      Descriptive statements about the specific nature of tidal energy is the La Rance Tidal Generation Plant...
