93,899 (and counting). That’s how many underwater images Barbara Crites has taken in photo-documenting marine life in the US Virgin Islands. Not bad for someone who’s “not really a water person”. She is proof that anyone can contribute to citizen science if they follow their curiosity, jump in with both feet and discover the world around them…and in turn, themselves. —BB

On Long Island’s east end, Bella (Courtney Stallings) and husband Noah (Jack Sachot) struggle to maintain their bluepoint oyster business against an onslaught of algal blooms, red tides and other threats from an ailing ocean.

In the summer of 2017, a team of scientists led by the Woods Hole Oceanographic Institution ventured a thousand kilometers off the coast of Brazil to explore the seafloor around a little-known cluster of islets called St. Paul's Rocks. One of those scientists, Diva Amon, a deep-sea biologist from the Natural History Museum of London, describes what it's like to venture into a dark, unknown world 1,000 meters (3,280 feet) below the surface—and why this type of research is key to understanding and protecting our oceans.

Reduce, reuse, recycle – it’s now become a standard mantra for those of us who understand the harmful impacts that plastics have on our environment, and ultimately our lives.
