That's what I thought. Kill the fossil fuels! ^^
And speaking of algae plumes, could we harvest the algae as a fuel source? I've heard of it being done.
You can win bio oil from Algae, from which you can make plastics, fuels and other carbohydrates. Some algae also produce hydrogen under some circumstances.
In theory you could use over fertilised water around farms to grow algae in. The algea use the nutrients and using a biorefinery you can win the nutrients back and other compounds like bio oil back. The clean defertilised water, could be injected into the local water system, making that cleaner as a result.
Please excuse my (probally) poor grammar
