Flashcards
Renewable Resources
Renewable Resources
Resources that can be replenished naturally at a rate comparable to or faster than their consumption. Examples include solar energy, wind energy, and hydropower.
Non-Renewable Resources
Non-Renewable Resources
Resources that are finite and cannot be replenished at a rate comparable to their consumption rate. Fossil fuels like coal, oil, and natural gas are examples.
E-waste
E-waste

Study Notes
Defining and Using Terms
- Resources can be renewable or non-renewable, and natural.
- Fossil fuels are a type of non-renewable resource.
- E-waste is electronic waste.
- Landfills are places where waste is disposed of.
- A garbage patch is a collection of marine debris.
- Plastic pollution includes microplastics.
- A circular economy focuses on reducing waste.
- Extended producer responsibility means producers are responsible for their products' end-of-life management.
- The 3 Rs (reduce, reuse, recycle) are principles for waste reduction.
Essential Questions
- A resource is something that is useful or valuable.
- Production and consumption of goods affect places and environments globally.
- Waste is produced in various locations.
- Waste can end up in landfills, the ocean, etc., this has reasons (and consequences).
- Waste management strategies are used to control waste.
Examples
- Different types of resources (renewable, non-renewable) include examples.
- The lifecycle of a product (e.g., a t-shirt) illustrates the journey of a product from starting materials to end-of-life, including resources, production, use and disposal.
- E-waste landfills in low- and middle-income countries demonstrate the impacts of disposal on the environment and the people there.
- A garbage patch is a collection of debris in the ocean (with negative environmental impacts).
Analysis at Different Scales
- Carbon footprint of individuals, countries, and the world measures the amount of CO2 emissions from products or activities.
- The amount of waste generated by various groups (individuals, households, countries) will vary.
- The flow of e-waste globally demonstrates the movement of unwanted electronic devices, and associated impacts.
- E-waste's impact on the population and the environment (e.g., in Ghana or India) showcases the potential for negative impacts of waste production, disposal, and management.
