Present | Past | Future?

With warm temperatures rising, and the poles melting, humankind could be forced to evolve and adapt to marine life. In this case, the future shows two different scenarios. In both of them we can see a human skull made out of Coccoliths, individual plates of calcium carbonate. 

If we live in a good and healthy environment, these plates would be strong and complete, which means that this new human species would have a strong skeleton. If ocean acidification changes the composition of water in the oceans, this would result in a more acidic water, and weaker coccoliths, which will make our skeleton become weaker.
