Mercury, Obviously.

This blog post is about what 2 elements from the periodic table are involved in my issue. Well, I have one pretty much handed to me on a silver platter. Another one could also be Oxygen because the Earth oceans cover 70% of our planet, and Oxygen is all around the ocean. Most aquatic creatures need it to survive so its a big part of this issue as fish are poisoned with mercury in the ocean and could die without oxygen, causing something else to come and eat it.
