What is the reason to save them?

None whatsoever, given that we already have the technology to breed oil
from algae feeding on human or animal waste. Admittedly it currently
costs $800 a barrel, but that is in laboratory conditions and the cost
could be expected to plummet were it to be done on an industrial scale.

I think that would be substantially more than wind turbines or PV.

There is good reason to think it could be made competitive with tar
sands or shale oil and oil is a much better source of power for road
transport than electricity.

In any case, that has nothing to do with algal oil production, which
is effectively making oil the way nature did, without the multi-million
year wait.
