Answer:
The answer is promoting the recycling of paper and aluminum on university campuses.
Step-by-step explanation:
To begin with, the idea of stewardship is borne out of love for the environment. Thus, people who practice stewardship believe that it is the duty of all humans to take care of the environment.
One of the ways of achieving the numerous goals of environmental protection is to promote the recycling of paper and aluminium. This is because the burning of paper constitutes environmental pollution while recycling aluminium prevents or avoids carbon dioxide emissions which are disastrous to the environment.
