What are the first problems that we should start learning / tackling?

I would love to learn more about the current state of oceans, and how possible innovations could benefit the oceanic biodiversity, along with all the biodiversity on land (including people across the world).

I really wish there was a way to bring back the XPRIZE ‘Weekly Reward Points’. Even if there won’t be bonuses for the XPRIZE Store, I feel that these points create a competing atmosphere hence making people actively involved and participate in topics of ones interest, hence keep the conversation going and a healthy discussion.
