As demand for these valuable metals has been skyrocketing, scientists have begun inventing new — and greener — ways to reuse what they have in hand.
That’s spurring new research to find a steady but safer supply of these precious metals, including in the United States.
This interplay between plastics and metals could affect how each affects the environment — and suggests opportunities for controlling their risks.
Instead of throwing unneeded things away, scientists recommend moving to a cycle of reducing, reusing, repairing and remaking old things into new ones.
Hungry bats are more likely to shed harmful viruses to people or livestock when they spread out to hunt food. Conserving forests may limit this risk.
