East Coast of Newfoundland's fish supply. Fish stock will never be as high as it once was due to over fishing. Without the notice of sustainable yield, resources humans rely on to survive will continue to deplete to a critically low stock.

Sustainable yield

Sustainable yield is a volume of production that is appropriate for harvest but also does not allow that substance to diminish over time, “Don’t bite the hand that feeds you.” An example of this would be “The collapse of the Canadian Newfoundland cod fishery.”. Where stocks of cod were over fished to the point where people lost jobs lost a source of income and most importantly a source of food.

Maximum Sustainable yield

Our interaction with the environment has greatly impacted negatively on the longevity of the non-renewable resources that we have. This is due to over harvesting or taking too much of these resources from greed or over production of large industries not caring about future generations. When inserting the concept of yields in to real world problems we would benefit the most by finding the maximum sustainable yield. This is the most we should take from something like a crop of oranges with still having enough oranges for years to come. To calculate this number we can use different equations such as Schaefer’s, Lotka-Volterra’s, or Fox’s models. Even though maximum sustainable yield is a step towards knowing how to sustain our resources more. It doesn’t always accommodate the differences in the real world.

Oil Resources

Oil has been a rising demand from consumers. Scientist have began seeing it from early on that the rate we are harvesting oil is too quickly to have it last that long in to the future. This also has been harsh on the planet due to oil spills, improper dismantling of equipment, and climate change. The Tragic event of Deep Water Horizon is the largest oil spill in history caused by the extreme demand of oil. "8,332-plus The number of species living within the vicinity of the oil spill. This includes the endangered Kemp's Ridley turtle, as well as more than 1,200 fish, 200 birds, 1,400 molluscs, 1,500 crustaceans, and 29 marine mammals and three other sea turtle specimens." Sustainability will be even harder to maintain if there are no protection procedures in the event of an oil spill, the spill will cause less product going to the consumer that was already strongly sot after. Less resource available to use in the future, and more demand from consumers will cause more pressure on the oil industries. We can either make consumers happy while cutting corners and running out of resources at a extremely fast rate, or we could make consumers mostly happy taking the proper steps and tests to protect and plan for longevity of our earth and future oil supply.

Predictions

Exercising the concept of sustainable yield in development will be more crucial for our planet in the next coming years. But as for now we can already see some plans that have encouraged the processes of sustaining our critical needs such as drinking water listed in United Nations 2012 report. "The target of halving the proportion of people without sustainable access to safe drinking water was also met by 2010, with the proportion of people using an improved water source rising from 76 per cent in 1990 to 89 per cent in 2010. Between 1990 and 2010, over two billion people gained access to improved drinking water sources, such as piped supplies and protected wells." This is an example of a plan to increase sustainable (Water that will be accessible over years and years to come) for more people in the world. The plan took place over a large tie frame so we didn't over produce the amount of water we could give out too quickly, if we did then it the water might have ran dry before we reached our target of 89 percent.
