In this section I will be talking about sustainable resource development, so lets start. Natural resources are materials or components that are found and extracted from the natural environment, it can be living/organic material (biotic) such as forests, fishes and fossil fuels, it can also came from non-living (abiotic) such as gold, iron, water, or air. Also Canada's economy is based around natural resources, they are inexhaustible they will run out if not managed correctly. Renewable resources are resources that can be naturally replenished but are renewable only if you use them at a slower level then it takes them to recover or regenerate, still many are being harvested at a faster rate example of a fast stock going in the danger zone: fish stocks are being harvested faster then they can reproduce. Tragedy of the commons is when a resource is not being take care of and not looked over its wellbeing for the greater good of future generations a example would be overfishing, people are overfishing without thinking of the consequences or without thinking of the resources wellbeing. Sustainable resource development is defined as meeting the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable yield management is knowing the amount of a resource that can be harvested without depleting the resource, also should ensure continued supply by allowing time to replace or reproduce. Non renewable resources do not produce naturally or do but at a very slow rate, if our extraction is faster then they can replenish it is non renewable a example is oil is continually formed, but takes millions of years to do so. Energy industry: energy is use is measured in joules (small amounts) and gigajoules (one billion joules). Energy production is divide into conventional (oil, coal, nuclear, hydroelectric) and alternative energy source (solar, wind, geothermal). energy in canada is used like this industrial (37%), transportation (30%), residential (17%), commercial/institutional (14%) and agriculture (2%).
