What Are the Biggest Challenges for Saving the Oceans?
By Tara Lohan
Oceans stretch across 70 percent of our planet, and the vast majority of the world beneath them is unmapped and unexplored. Their depths may still hold many secrets, but we know they face serious risks from overfishing and pollution. The biggest threat of all is climate change, which could affect billions of people in coastal communities, said marine biologist and conservation strategist Dr. Ayana Elizabeth Johnson.
Johnson is the founder and president of Ocean Collectiv, a strategy consulting firm that looks at conservation solutions through a social justice lens. Developing those solutions has never been more necessary. As Johnson said, "The lack of public and corporate reaction and response to the recent Intergovernmental Panel on Climate Change report—which tells us we have 12 years maximum to avoid catastrophic climate change—is terrifying."
We talked to her about what's at stake and the types of solutions she thinks are most promising.
In order to protect our oceans, what policy changes do we need at the national and international levels?
The top three are ending the use of fossil fuels, closing the high seas to fishing and protecting 30 to 50 percent of the coastal ocean.
Beyond policy, what else should we be focusing our efforts on? Enforcement? Public engagement? Technology?
We need to be pressuring corporations to adopt sustainable practices ASAP and to raise the bar for what qualifies as sustainable. For example, some of the fisheries being certified as sustainable by the Marine Stewardship Council are far from deserving of that label.

From an environmental-justice standpoint, who stands to lose the most if we fail to adequately protect ocean and coastal ecosystems?
Poor people and people of color in coastal communities will be most at risk. Sea-level rise, overfishing, pollution and coastal development affect them first and worst, and they have the fewest options for alternative livelihoods or relocation.
What ocean-related issues did you follow in this year's election cycle?
Climate change! I'm excited that Jared Polis has been elected governor of Colorado on a platform of getting Colorado to 100 percent renewable energy by 2040, the most ambitious goal yet for any state.
However, because the Democrats won the House, Congresswoman Eddie Bernice Johnson, who lists climate change science and mitigation as priorities, is poised to take the helm of the science committee, which is cause for hope.
What's one of the best solutions you've seen used to combat an ocean-related problem or to help people who depend on the ocean?
Ocean farming. Regenerative ocean farming, as pioneered by Greenwave and others, means growing seaweed and shellfish (oysters, mussels, clams)—not constructing more salmon farms. Seaweed and shellfish don't need to be fed; they grow with just sunlight and the nutrients and plankton already in seawater.
As pioneering ocean farmer Brendan Smith put it, "the real kicker" is that these low-maintenance ocean plants and animals "require no fresh water, no deforestation and no fertilizer," plus they improve water quality and create habitats for other species.
Because seaweed grows so quickly (kelp can grow over one foot a day) it can provide healthy food and clean biofuels while being a significant part of the climate solution. And developing this industry creates good jobs. (There's more about this in my recent article in Scientific American, co-authored with my mom: "Soil and Seaweed: Farming Our Way to a Climate Solution.")
Also, Mr. Trash Wheel. It collects trash from rivers or harbors before it ends up in the sea. So practical and effective—solutions don't need to be high-tech.

Climate change is already here. It's not something that can simply be ignored by cable news or dismissed by sitting U.S. senators in a Twitter joke. Nor is it a fantastical scenario like The Day After Tomorrow or 2012 that starts with a single crack in the Arctic ice shelf or earthquake tearing through Los Angeles, and results, a few weeks or years later, in the end of life on Earth as we know it.
Air pollution particles that a pregnant woman inhales have the potential to travel through the lungs and breach the fetal side of the placenta, indicating that unborn babies are exposed to black carbon from motor vehicles and fuel burning, according to a study published in the journal Nature Communications.
Teen activist Greta Thunberg delivered a talking-to to members of Congress Tuesday during a meeting of the Senate Climate Change Task Force after politicians praised her and other youth activists for their efforts and asked their advice on how to fight climate change.
The University of California system will dump all of its investments from fossil fuels, as the Associated Press reported. The university system controls over $84 billion between its pension fund and its endowment. However, the announcement about its investments is not aimed to please activists.

World leaders have a formidable task: setting a course to save our future. The extreme weather made more frequent and severe by climate change is here. This spring, devastating cyclones impacted 3 million people in Mozambique, Malawi and Zimbabwe. Record heatwaves are hitting Europe and other regions — this July was the hottest month in modern record globally. Much of India is again suffering severe drought.

The United Nations Secretary General says that he is counting on public pressure to compel governments to take much stronger action against what he calls the climate change "emergency."
