70% of the earth is covered by water.
If light penetrated about 20 m, it corresponds to a volume of 4.46x10^9 km^3.

In these 4 billions of cubic kilometers of water there are lots of algae, sucking CO2 and transforming them into life.

Say each building makes up for 10 cubic meters of water to grow algae (10 cubic meters are 10,000 liters), we would need only about 4 x 10^15 buildings (or about 500,000 buildings for each man on the planet) to affect a 1% of CO2 absorption.

Can we develop industrial and agricoltural processes that avoid polluting our waters instead?

The calculation used actually 50 meters for light penetration as infrared light penetrates deeper, but algae still use it.
