Answer to Question 1

D

Answer to Question 2

We cannot expect science to solve environmental problems for us. Most of the decisions and necessary actions fall outside pure science in the areas of values, ethics, morality, and philosophy. The solution to environmental problems, if one exists, lies in education and action. Each of us is obliged to become informed on issues that affect Earth, its ocean, and its air-to learn the arguments and weight the evidence. Once informed, we must act in rational ways. Chaining yourself to an oil tanker is not rational, but selecting well-designed, long-lasting, recyclable produces made by responsible companies with minimal impact (and encouraging others to do so) certainly is.
