How we choose to pay has hidden costs for the planet
Whether cash or credit, phone apps or digital currencies — all forms of payment have behind-the-scenes costs. And these can vary dramatically.
- Animals
Bees and butterflies struggle to find flowers in polluted air
Emissions from cars and trucks make it harder for insects to find flowers. That in turn reduces flower visits and pollination, a new study finds.

Widely used pesticides may threaten Earth’s ozone layer
Data show a major class of long-used “eco-friendly” copper chemicals unexpectedly react with soil, making gases harmful to Earth’s protective ozone layer.

Scientists Say: Pollution
Pollution is any substance or form of energy released into the environment that is harmful to people or other living creatures.
- Chemistry
Clothes dryers may be a major source of airborne microplastics
Scientists thought washing machines were a leading contributor of microplastics. Now it appears dryers may be an even bigger problem.
