We can completely replace petroleum by growing bioengineered saltwater algae on about 3% of the open ocean surface. Not only does algae convert CO2 into O2 creating a closed loop it removes pollution from the air and water. There will be an explosion of new ocean life because algae is the beginning of the ocean food chain.

Doesn't sound like a bad idea, if it can be made commercially viable.
