We use it and then we throw it away! In Why Does Litter Cause Problems?, Isaac Asimov explains how litter can destroy nature and shows how recycling can make our world a cleaner, healthier place.

This is the last book in the “Ask Isaac Asimov” series to be written by Asimov himself—later books appear to have been authored by Elizabeth Kaplan and are not listed here. I have no particular enthusiasm for the book, but no particular objection, either, to its text or description of the problems that litter can cause and what even young children can do about them.
