Human impact on the ocean?

[on_two_wheels]

There's been several threads recently about touching, shark feeding, our impact. Ironically, today this shows up on my aol screen.

It's a fate that faces many species of fish and mammals in our oceans. Unfortunately, everyone is focused on being GREEN and Global Warming and not looking at where our O2 comes from...the Oceans. I am not sure how much more of a slap in the face we need to change the global community. Hopefully we have not signed our own fate and can change the practices that are destroying the ecosystems above and below water!

Erm.... Photosynthesizing plants?

Being green can be bad for the environment. As the US go full steam with Ethanol production, more fertilizer will be used, more run off will occur in the mississippi river, and the larger the "deadzone" will be in the gulf of mexico.

Helping gas guzzling SUV owners by growing corn for ethanol is simply killing our environment. I welcome our $10 per gallon gas while I puts around in my subcompact and get 40 mpg cruising at 60 mph.

It's good to see someone has similar views. I don't mind the "crash" course for cert as cert is required for air. If an intensive course was cheap It would be better for new divers (me). But the Industry HAS become "cookie cutter". Once certified (cross fingers) it will be up to me and me alone to hone basic skills, and pic all your brains for better ways to empty a tank without inadvertently killing the last living whatchamacallit.

It is a sad trend I am afraid. I think most people, even still today cannot comprehend the vastness of our planet and it's resources, and their lack of vision makes it seem larger than it is. Truth is our resources are limited and the oceans are too small for all the crap we have put in them. The only question really is what changes are coming, how will that effect us and the rest of the planet, and can we/should we try to stop those changes?

Like a senior citizen on 8 different prescriptions, as each solves one problem but creates another, we need to know what effect our solutions have before we charge in. As one poster already mentioned ethanol, but there are and will be others as well.

Wow, I didn't know that about Algae...learn something new every day.

How about marine archaeology? This thread talks about their 100 mile territory and if you check their website, second link, you can see the destruction of reefs. I would venture to say that this type of exploration takes a big toll on the sites. Is it justified?

I'm not picking on these guys in particular but since they posted here, it got me to thinking about this type of "scientific" research. I did post about this in the "Touch or no touch" thread and ironically had no responses.

Noted your post there, but I think it's such a large topic in/of itself that it warrants a separate discussion, hence no reply there, at least from me. It's a big enough issue, and more foreign to a lot of rec divers, I think, because they've never "been there" as far as archaeological salvage, that it's hard to know where to bite off a piece of it and start chewing.

Maybe it would be useful if a proponent of archaeological salvage, or research, or whatever it is called when the ocean bed is excavated, were to post their rationale here. Actually, I believe it's already been done on this board, but not sure where ...
