Biodegradable

The video discusses the role of soil bacteria in biodegradation and the challenges posed by non-biodegradable man-made polymers. It highlights the environmental impact of these polymers if not recycled. Scientists are working on developing biodegradable alternatives that are as effective and affordable as current polymers, including plastics, rubbers, and adhesives.

What is the primary role of soil bacteria in the context of polymers?

• To recycle non-biodegradable polymers

• To create new polymers

• To break down biodegradable materials

• To enhance the strength of polymers

What happens to many man-made polymers if they are not recycled?

• They remain in the environment for decades

• They decompose quickly

• They become more useful over time

• They turn into biodegradable materials

Why is it important to develop biodegradable alternatives to current polymers?

• To reduce environmental impact

• To decrease the strength of polymers

• To increase the cost of production

• To make polymers more colorful

What are scientists aiming for in developing new biodegradable polymers?

• Higher cost and lower quality

• Same quality and cost as current polymers

• Lower quality and higher cost

• Completely different properties

Which of the following is NOT a type of polymer mentioned in the video?

• Adhesives

• Metals

• Rubbers

• Plastics
