Global Human Influences On Ocean Ecosystems Mapped

ScienceDaily (Feb. 14, 2008) - For a bird's-eye view of human impacts on the Earth, scientists can study satellite images showing the continents in mottled colors that correspond to vegetation, desertification or human habitation.

But those photos cannot tell them much about the big blue mystery, oceans, and how human activities affect them.

Now, a team of researchers has constructed the first global map of human influences on marine ecosystems by gathering and interpreting massive amounts of data from the professional literature and from researchers around the world.

This study suggests that about 41 percent of oceans bear a serious human "footprint " and that few blue spots on our planet are likely pristine, less than 4 percent.

"A series of papers have highlighted the role humans are having on the degradation of the oceans, through specific activities," said Fiorenza Micheli, an associate professor of biology at Stanford.

"It's timely to put it all together-to show how all the different effects sum up."

Micheli said maps of human influence should "guide ocean zoning and management of coastal waters."

Scientists increasingly advocate zoning oceans to protect the hidden ecosystems below the surface.

"By seeing where different activities occur and whether they occur in sensitive ecosystems, we can design management strategies aimed at shifting activities away from the most sensitive areas," Micheli said.

The researchers compiled data on 17 different human impacts to oceans, including fishing, coastal development, fertilizer runoff and pollution from shipping traffic.

Previous studies have worked on a smaller scale, or have focused on only one ecosystem or human activity, examining a single piece of the global puzzle.

To make the picture complete, Micheli and her colleagues built a global map detailing how these numerous human impacts would add up and affect 20 types of ecosystems.

Here's the map, for anyone who doesn't want to click through. Pretty gross even on a non-environmentalist front.

click here for link -click daily, and all sister sites daily
click here for link -click each project daily
click here for link -click (guess how often) daily

Instead of posting depressing images of terrible things, how about you also provide some ways to help out?

Thanks for the links, the only one I had was therainforestsite...

Easy: using more reusable items (cloth bags, never using disposable utensils, etc.); recycling, especially plastic; eating local and/or organic (check where your organics come from though - anything outside the country is worthless. CSAs are almost everywhere though); eating less processed foods; unplugging your electronics.
Harder: going vegetarian or vegan; composting; living in the smallest space possible.
Hardest: moving into an urban environment; investing in a good bike or comfortable walking shoes and selling your car (zipcars/flexcars are available in almost every city incase of emergency); solar panels or windmills - go as far off the grid as possible.


A lot of the problems with pollution in the air and water is because we waste so much energy here on land.

You have to know the details and scope of a problem before you can appropriately address it. I'm not sure this one is getting fixed that easy as going to a website and clicking on a link.
