Dear all,
ecological restoration is the greatest challenge of our century. We have to restore what we have destroyed to have functional ecosystems.
Hence, the aim is to restore ecological function.

When it comes to coral reefs, we have to implement both restoration and curbing CO2 emissions.
Conservation and restoration must work hand in hand to give coral reefs a fighting chance.
It is time we stop quarreling among ourselves and find constructive ways to collaborate.

Sometimes, the challenge to restore coral reefs seems as difficult as the Moon landing was back in the 1960s.

Paraphrasing President John F. Kennedy,  and changing a few words, we find a powerful message:

We choose to restore coral reefs. We choose to restore coral reefs in this century and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.

Hi Les, that's an interesting discussion and one that I've been thinking
about a lot recently. I really don't care about who came up with the
"super" term first or how it's used today, but I do care about the
restoration debate. And in this case I think I am on Colin's side. I do
100% agree with Terry (and Colin, from what I read) that the greatest
threat to corals today is climate change, and the need to address it is
urgent, but I think that even as we address climate change we need to help
corals in other ways. Here is why:

https://theconversation.com/what-would-happen-to-the-climate-if-we-stopped-emitting-greenhouse-gases-today-35011
[https://images.theconversation.com/files/66654/original/image-20141208-5137-1fc8syt.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=250&h=140&fit=crop]<https://theconversation.com/what-would-happen-to-the-climate-if-we-stopped-emitting-greenhouse-gases-today-35011>

What would happen to the climate if we stopped emitting greenhouse gases today?<https://theconversation.com/what-would-happen-to-the-climate-if-we-stopped-emitting-greenhouse-gases-today-35011>
theconversation.com<http://theconversation.com/>
Earth’s climate is changing rapidly. We know this from billions of observations, documented in thousands of journal papers and texts and summarized every few years by the United Nations’ Intergovernmental…




The article above summarizes results from different papers that show that
even if we stopped CO2 emissions today, Earth's temperature would take
decades to stabilize and would still be higher than pre-industrial levels.
So, to save corals we cannot solely focus on curbing CO2 emissions. To me,
restoration does three things:

1) It buys corals time. Restoration can keep populations going or make them
viable again, even when done on a small scale (if done the right way). And
it can just help them survive long enough to be around when climate
stabilizes.

2) By keeping populations going, it gives them more chances to adapt
naturally. Every bleaching event is a severe bottleneck, and everything
that survives has a big chance of surviving the next bleaching event. But
if the closest coral colony of that species is 10km away, their gametes
will probably never meet. Restoration (again if done the right way) can
help corals adapt by connecting those stragglers.

3) It gives people hope. When people realize that temperatures won't go
back to normal any time soon even if we stop CO2 emissions now, they will
simply think that there is nothing that can be done for corals and will let
them go. I don't want to see that happening.

Having said all of that, I would probably still be on Terry's side if I
thought the fight climate change was competing with resources for coral
restoration. But I don't think they are. I think the climate change fight
is a global one and has to be mostly driven by governmental and energy
industry initiatives, whereas coral restoration is driven by local and
foundation support. As you know, my views are very different when it comes
to MPAs. I think very large (and based on everything I read, not effective)
pelagic MPAs are sucking the few resources available for marine protection
in tropical countries, and that's a big problem.

Cheers,

Luiz
