This is a series on a topic of great controversy. Extrapolations takes a close look at the near future of the world based on extrapolating current environmental data into potential future numbers. What might these environmental changes do to humans, animals, insects, plants? What could sea level changes mean? What will increased temperatures do to human life. What will happen to the air we breath. What new medical conditions could develop? The series only provides episodes of stories depicting these questions. The were a couple of weak episodes so couldn't give it a 10. The final episode did a good job of making a statement about what the developers of the series want you to take from it. If you are an environmentalist, you will likely love it. If you believe climate changes is a hoax, you may want to skip this one.
