Listening Practice 1

Tony: Mom, what is this word? Bio-de-grade-able?

Mom: Biodegradable, Tony. It means things that are environmentally-friendly. For example, I buy biodegradable soap. It doesn’t cause pollution like other soaps.

Tony: Right.

Mom: OK, listen. Biodegradable things disappear into the soil or water when you throw them out.

Tony: Oh! Wait! Now I remember. Like a banana peel, right? It will disappear in a week. We learned about this in science class.

Mom: Exactly! A banana peel is biodegradable, but things like plastic bags are not. They can take up to 500 years to decay. That is why it is better to use biodegradable products.

Tony: OK.
