Ocean decline leads to Spain's jellyfish patrol

A jellyfish plague has Spain's environment ministry planning a jellyfish patrol this summer. The goal: scoop up jellyfish and protect people from stings.

Overfishing, drought, and global warming are likely causes of the stinging horde.

This is just the most recent in a long series of stories about jellyfish explosions worldwide, and even fishing for jellyfish. This is Jeremy Jackson's "rise of slime," a sad story of a shifted baseline.
