In the Pacific Ocean, between Hawaii and California, at least 79,000 metric tons of plastic has coalesced to create the Great Pacific Garbage Patch.

It’s also a huge hazard for marine life, killing up to 1 million seabirds and 100,000 marine mammals each year via ingestion ...read more

We even use ‘mirage’ as a metaphor: I imagined us together for the rest of our lives, but that future was just a mirage. But what are mirages when you get th ...read more
