1. While it’s true that the primary effect of carbon dioxide buildup is to warm the Earth and to change the climate, some of that carbon dioxide is absorbed by the oceans, and when water absorbs carbon dioxide, it becomes more acidic. … That has some implications for sea life, especially organisms that form shells: In an acidic environment it’s harder to form a shell, and because a lot of these organisms are at the very base of the ocean food chain, there could be some real disruptions to that part of our food supply.
