One of the most powerful natural tools we have to protect our environment lives out of sight, just beneath the ocean surface: seagrass.

In fact, scientists estimate that seagrass meadows are resp...

And the consequences for people missing their court date, even by accident, can escalate quickly. Pew's Mic...

These vast waters—the high seas— cov...

Take a trip with us in this episode of "After the Fact," in which Amelia Moura an...
