According to the UN’s Food and Agriculture Organization, 70 percent of the world’s fisheries have been depleted by overfishing. Even as we move towards a greater reliance of aquaculture - providing nearly 50 percent of the fish eaten worldwide – it may not be enough to meet the growing demand. Add to this the fact that fish farming suffers from many of the same problems as industrial livestock operations – the spread of disease and waste – along with carrying the fear that these “cultivated species” could potentially overrun native populations, and we’re facing a scenario with no easy solution.

Cuttlefish Inspired Flat Screens
Researchers at MIT are using biomimicry to create TV screens that use dramatically less energy than existing models. Using the camouflaging techniques deployed by cuttlefish as a model, the MIT group has been able to power these displays with less than 0.01% of the power used by conventional screens.
Ecofriend explains:
The researchers stated that cuttlefish change their appearance in a few seconds by secreting special chemicals to alter the spacing between their membranes. This low-energy technique seen in cuttlefish has been mimicked by the researchers to develop low-power displays.
These researchers have developed a prototype screen that is several inches across but [...]
