“Where do we start?” It’s a question that I’m asked every day in relation to the opportunities we have to put the ocean at the center of the most pressing issues of our time.
One of our readers, who is very concerned about increasing CO2 emissions, asked that question in a comment on my last blog, where I detailed how rising carbon pollution is the greatest risk to the ocean and the resources—food, water, air, energy—it provides to sustain us.
The first step we need to take is to find out more about the species, people and places that are already feeling the effects of increased carbon pollution. The ocean is absorbing more and more of our carbon emissions, and its waters are becoming more acidic as a result. Ocean acidity has already increased 30 percent in the past few decades, and we are starting to see real impacts on species that depend on calcium for their shells.
