GCSE Chemistry - Sustainable Development - Reuse and Recycling #72

The video discusses sustainable development, emphasizing the need to meet current needs without harming future generations. It highlights the importance of using renewable resources over finite ones and the role of energy efficiency in manufacturing. The video also covers the processes of reusing and recycling materials, including glass and metals, to minimize environmental impact.

What is a key principle of sustainable development?

• Focusing solely on economic growth

• Ignoring environmental impacts

• Meeting current needs without harming future generations

• Using as many resources as possible

Why is using wood considered more sustainable than plastic?

• Plastic is more durable

• Wood can be regrown, unlike plastic

• Wood is lighter than plastic

• Wood is cheaper to produce

How do chemists help reduce the environmental impact of manufacturing?

• By making processes more efficient and reducing energy needs

• By using more plastic in products

• By ignoring energy consumption

• By increasing the use of fossil fuels

What is the most sustainable action to take after using a product?

• Store it indefinitely

• Reuse or recycle it

• Burn it for energy

• Throw it away

What is a common step in recycling metals?
