What does a responsible citizen do for the environment?

Correct answer: Uses resources carefully

Environmental responsibility means understanding that personal choices affect shared natural resources and then acting to prevent unnecessary damage. A responsible citizen uses water, electricity, fuel and materials carefully, avoids littering, separates waste when facilities exist, and protects public spaces and living organisms. Therefore, option B is correct. Leaving taps open wastes water, cutting trees without reason harms habitats, and throwing waste in the open can pollute soil, water and air. Responsible behaviour is not limited to government or environmental groups; ordinary daily habits at home, school and work collectively reduce resource use and pollution and encourage others to act sustainably.
