GEOGRAPHY: NATURAL RESOURCES AROUND THE WORLD  NATURAL RESOURCES Why do we need them? People need many things to live both safely and comfortably Ex. Housing, food, water for basic needs Many other things for enjoyment All these things require materials to manufacture them and some require power/fuel to make them work Natural resources - air, water, plants, sunlight, soil, rocks, animals, oil some are underground, some need to be mined not evenly distributed around the world people tend to live near natural resources that important to the population Types of Natural Resources Water Resources Forrest Resources Animal Resources Solar Power Precious Metal, Wind Power Crude Oil Natural Gas Land Resources Minerals and Rocks There are 3 types of natural resources: 1) Renewable 2) Non-Renewable 3) Flow  Renewable Resources Renewable resources are resources that naturally replenish themselves from time to time. within our lifetime. (ex. water, trees, plants, animals) Non-Renewable Resources Resources with a finite amount. They are unable to be reproduced within our lifetime. (ex. minerals, oil/fossil fuels since take millions of years to produce).  Flow Resources Not renewable or non-renewable. They must be used when and where they occur in nature. Ex. Solar Power: When the sun is shining and there is a solar panel,, the energy can be captured. If there is not a panel where the sun is shining, nothing can capture that current solar energy and cannot be recaptured.  Your Task: Exit Card Questions Due end of class *on google classroom* Renewable Resources Reminder: Renewable resources are things that can replace themselves in a relatively short period of time. We will discuss three examples: 1) Trees 2) Managed Forests 3) Wildlife Renewable Resources: Trees Cut down trees to make many items (houses, furniture, paper) A new tree planted will take a many years to grow to replacement size or maturity, depending on the type Hardwood maple: 150 to 200 years Pine Tree: 25 to 40 years Bamboo Trees: 7 years Renewable Resources: Managed Forests Trees are renewable only if how we use and replace them is managed In Ontario, 90% of forests are on Crown lands Meaning owned by the provincial or federal government Of these lands 40% of them are managed forests Managed forests considers how trees will grow fastest and healthiest It takes into consideration: The other uses of the forest (ex. wildlife) Indigenous and local community input i.e. tries to be sustainable (a new tree is planted for every tree cut down) Renewable Resources: Wildlife Example: Bison in 1800s There were 30 billion bison in North America Indigenous people hunted them for good and pelts (i.e. rugs, clothing) Europeans settled, traded for buffalo pelts, introduced using funs and horses to hunt efficiently Bison were hunted to NEAR extinction Example: Cod in 1497 to 1997 In NFL, there was once a large abundance of cod By 1997, overfishing caused cod fisheries to shut down in Canada Fishing/Fishery related jobs were lost Renewable Resources: Wildlife Renewable when conservation practices are put in place This is when rules or certain practices are enforced to prevent extinctions or dramatic decreases in population size “Reserves” where hunting is not allowed in certain areas Special permits to allow hunting Renewable resources need to be managed, consider sustainability or else - the resource becomes non-renewable  Your Task: Exit Card Questions Due end of class *on google classroom* Non-Renewable Resources Resources with a finite amount. They are unable to be reproduced within our lifetime. (ex. minerals, oil/fossil fuels since take millions of years to produce).  Non-Renewable Resources Found in nature, take millions of years to create Example: minerals and fossil fuels: oil, natural gas, coal Made from plant and animal matter that have been buried and crushed under the earth’s surface Millions of years, remains turn into oil (water plants/animals) or coal (woody plants) - these both make natural gas To make fossil fuels, need to be under pressure (ex. weight of rock or water pushing down) and high height (ex. under the earth’s crust) Always found underground (10m to several km) below earth’s surface, oil and gas - along tectonic plate boundaries  Non-Renewable Resources The Downside Fossil fuels took millions of years to form Humans are using the entire supply in a few hundred years, leaving nothing for the future generations 2019, 84% of the world’s energy consumption came from fossil fuels When burning fossil fuels, they produce greenhouse gases Greenhouse gases cause climate change Trap heat in the earth’s atmosphere Increases overall temp of the earth Burning fossil fuels - causes air pollution/smog Causes respiratory diseases  Your Task: Write a 5 sentence paragraph answering the following question: Is the burning of fossil fuels good or negative for the environment? Intro sentence 2 reasons and explain sentences (3) Conclusion sentence  Flow Resources Remember, a flow resource is neither renewable nor non-renewable Must be used where and when it occurs and there is an unlimited supply Flow resources are natural resources or processes that humans have NO influence over Ex. Sunshine, tides, wind, running wanter and geothermal energy  Flow Resources Flow resources will not be exhausted over time not because they will renew themselves (i.e. wind does not renew itself) They will have a source that is so large that it will not run out (ex. the sun) They are a result of a process that will repeat naturally (ex. wind or rain)  Flow Resources Flow resources are beneficial to humans since using them does not create a negative environmental impact limitless supply so a sustainable option We use flow resources daily Ontario - 25% of power used comes from the Niagara Falls Ontario Hydro Plant (also generates power in NY) Hydroelectricity uses the force of water being pulled from gravity to turn the turbines to make energy The higher the water drops, the more force is applied to the turbine, creating more energy What are the benefits? Clean, efficient, reliable and sustainable Disadvantages? Disrupts plant and animal habitats  Your Task Pick one of the following resources: Wind power Solar power Hydro power Create a poster (by hand or digital) detailing the following What is it? How does it work? What are the advantages? What are the disadvantages? Include at least 2 photos
