The Mediterranean's warming waters are drawing hundreds of invasive species

The Mediterranean is warming rapidly, and hundreds of invasive species (like lionfish and puffer fish) are moving in and displacing traditional marine life.
Coastal communities are feeling it — mussels and native fish are collapsing, livelihoods and local diets are being disrupted, and some invaders are toxic.
Possible responses include commercializing edible invaders, paying fishers to remove harmful species, tighter ship ballast/hull rules — and, ultimately, reducing fossil fuel use through global action.
