The pain-in-the-ass weed, also known as Palmer amaranth, claims the annoying weed holy grail — it is invasive, adaptive, and herbicide-resistant. A single plant, undeterred, can grow over six feet tall and produce up to half a million tiny seeds.
It distributes easily, and young seedlings continue to germinate even after the cash crop is planted.

Whatever your burger pleasure, targeting meat-eaters is a smart move — there are way more of them than there are vegans and vegetarians.

The tube–roughly the length of a football field–is one piece of a larger system that will set sail for the Great Pacific Garbage Patch this summer, where it will begin collecting some of the 1.8 trillion pieces of plastic trash brought there by ocean currents.
