3 INTRODUCTION A natural resource is anything found in nature that can be used by people. A natural resource is anything found in nature that can be used by people. Nature resources can be divided into three categories: Nature resources can be divided into three categories: Renewable Renewable Non-renewable Non-renewable Flow Flow

4 Renewable Resource Wild animals hunted for food. Wild animals hunted for food. Wild plants gathered as sources of food or grasses that feed livestock.

Soil for producing agricultural crops.

5 Non-renewable Resources Metallic minerals such as copper, iron, and aluminum. Non-metallic minerals such as diamonds, potash, sand and gravel. Fossil fuels such as coal, oil, and natural gas.

7 Sustainable Resource System A sustainable resource system is one that will last into the future and one in which natural resources are not used up faster than that can either renew themselves, be recycled, or be replaced with other resources.

9 Valuing Resources Natural resources may also be valued for their ecological benefits, such as the ability of trees to produce oxygen and remove carbon dioxide from the atmosphere. Natural resources may also be valued for their ecological benefits, such as the ability of trees to produce oxygen and remove carbon dioxide from the atmosphere. Natural resources have aesthetic benefits. People find forests, the green open spaces of farmland, soil for growing plants, fresh water, wildlife and the Canadian wilderness beautiful and of great value to them, both physically and psychologically.

10 The Trade Off We need natural resources for many things, like jobs, food, clean air, etc. But if we use up the resources without thinking about future generations, then we become irresponsible.

United Nations suggest 50 litres of water per person per day.

44 Diverting Water Water diversion is the rerouting of water from one drainage basin to another. Privatization of water means a corporation owns water supplies whose main purpose is to make a profit.

45 Groundwater Contamination Groundwater is held in soil and rocks that are located under the surface of the Earth, and it is naturally filtered by several layers of sand and gravel, which help to clean it.
