Answer the questions in detailed: -

Question 1: - Earlier, we had a discussion about the role of biologists in combatting climate change and biodiversity loss. Several of you indicated that biologists should play roles in setting federal policies, etc. Can you think of ways that biologists could positively impact these situations at more local levels?

Question 2: - Do you think there will be any changes in your life--or more broadly in our society--that you anticipate retaining after the pandemic has passed? What do you think their effect will be on our ecological footprints?
