Plastic pollution: researchers discover worms who can safely biodegrade various types of plastic

The video discusses the issue of plastic waste, highlighting that only a small percentage is recycled. It introduces mealworms as a potential solution, as they can consume and biodegrade Styrofoam and other plastics. The bacteria in their gut help break down the plastic, converting it into carbon dioxide and biodegradable fragments. A study found that mealworms can consume a significant amount of Styrofoam daily, and their droppings are safe for use as soil. This suggests a promising method for reducing plastic waste and its environmental impact.

What percentage of the 33 million tons of plastic discarded annually is recycled?

• Exactly 33%

• Less than 10%

• About 25%

• More than 50%

What unique ability do mealworms have that can help reduce plastic waste?

• They can consume and biodegrade Styrofoam.

• They can convert plastic into water.

• They can fly and transport plastic.

• They can dissolve plastic with their saliva.

How much Styrofoam can 100 mealworms consume in a day?

• 50 to 55 milligrams

• 34 to 39 milligrams

• 20 to 25 milligrams

• 10 to 15 milligrams

What happens to the Styrofoam after mealworms consume it?

• It is completely digested and disappears.

• It is converted into water.

• Half is turned into carbon dioxide, and the rest is excreted as fragments.

• It is stored in their bodies.

What is a potential use for the droppings of mealworms fed on plastic?

• They can be used to make plastic bags.

• They can be used as a food additive.

• They can be used as a fuel source.

• They can be used as soil for crops.
