Transcript of Notes: Human Use of Natural Resources

Video: The Science of Overpopulation
Threats to Natural Resources
-Overpopulation is a condition where the human population exceeds the Earth's carrying capacity.
-The world's human population is increasing at a very fast rate
Conservation of Natural Resources
-Cities worldwide are responsible for 60-80% of global energy consumption and 75% of carbon emissions, consuming more than 75% of the world's natural resources.
Resource Recovery
-Waste is now being viewed as a
potential resource
and not something that has to end up in the landfill.
Resource Recovery
is the separation of certain materials from the waste we produce, with the aim of using them again or turning them into new raw materials for use again.
-It involves composting, recycling, and biomass for energy
-For example, waste water can be treated and used for gardening, agriculture, cleaning, and refilling underground aquifers.
Notes: Human Use of Natural Resources
EQ: How does the expanding human population impact the environment and what can humans do to conserve natural resources?
The increase in human population means there will be pressure on almost all natural resources because:
Land Use
More land will need to be cultivated and developed for housing, factories, warehouses, etc. More land used for farming and agriculture. More chemicals will be used to increase food production.
Demand for wood, food, roads and forest products will be more. People will use more forest resources than they can naturally recover.
More fishing will need to be done. Some fishing methods are not sustainable, destroying much more fish and wildlife in the process.
Need for more:
More items (communication, transportation, education, entertainment, clothing, food, and recreation) will need to be produced, meaning that more industrial processes (factories) and more need for natural resources.
Climate Change:
Pollution, resource consumption, and mining cause and overall increase in global temperatures, wind patterns and climates. The change in climate patterns as a result of excessive carbon dioxide is hurting biodiversity and natural resources
Environmental Pollution
Pollution affects the chemical make-up of soil, rocks, lands, ocean water, freshwater, underground water, and other natural resources. This often has catastrophic consequences.
How can we reduce the use of natural resources?
Education and Public Awareness
When people understand how useful our natural resources are, they will be better at preserving it.
Reduce, Reuse, and Recycle
Individuals, organizations, and nations: People should give back to the environment by reducing waste, recycling waste, and becoming part of the solution.
Government and Policy
Governments must enforce policies that protect the environment.
