Protect deep sea ecosystems to preserve potential medicines

Deep sea mining threatens undiscovered ecosystems around thermal vents that harbor unique organisms with untapped potential for new medicines.

The mercury level in farmed fish is more dependent on their feed than their environment, as switching from anchovy to tuna byproducts can cause a significant spike.

Thaw fish in fridge with paper towel for superior texture

For superior texture, thaw frozen fish by removing it from the plastic, wrapping it in a paper towel, and placing it in the fridge to wick away moisture.
