Answer:
- Carefully and responsibly using a resource
- Putting paper in the trashcan
Explanation:
Conservation can be defined as: "prevention of wasteful use of a resource". This fits well the option chosen.
Also, putting paper in the trash can doesn't mean anything for sustainability. This is just the organization of trash and disposal. Environmental sustainability is "the ability to maintain rates of renewable resource".
