New research makes the case that it's not enough to consider the planetary impact of a growing population, alone.
New catalysts made from abundant and inexpensive materials could lead to a commercially viable way to convert carbon dioxide into plastics and other useful products.
Certain salt-loving microorganisms could eat seaweed and produce biodegradable plastics in a sustainable fashion.
