The document presents 10 statements about possible future environmental issues and asks the reader to indicate their level of certainty for each one occurring on a scale of 100% sure it will happen, 50% sure, or 100% sure it won't happen. It then prompts the reader to write a sentence expressing their opinion on one of the statements using words like "certain", "sure" or "won't" to indicate their level of confidence. Some of the statements addressed include most cars being electric, alternative energy becoming more important than oil, and the climate getting worse.
