There are some things that are just too damn big to fit into our little brains: The scale of the universe, the size of a T-Rex, the amount of plastic in our oceans. To wrap our heads around it, we need to resort to analogies, comparisons, or shrink the problem down into something comprehensible—so how's this? The equivalent of an entire NYC garbage truck full of plastic enters our oceans every minute, and by 2050, there will be more plastic in the sea than fish. Or this: There are 500 times more pieces of plastic on earth than there are stars in our galaxy. But despite the problem being so immense, sometimes we don't notice it until it washes up on our favorite beach, or gets into our favorite food (yep, there are probably microplastics in that tuna you're eating). This week on the Travelogue podcast, we try our best to understand the magnitude of plastic's hold on our ocean ecosystems—and talk about what you can do to end it.
