Despite Brazil’s recent expansions of protected areas, research shows that the favorite habitats of whales and dolphins are still threatened by human activities.
Plants need phosphorus, and other nutrients, to grow. But soil tests can’t tell if there’s too much.
The atmosphere is a complicated place. Warm temperatures in one spot can contribute to brutally cold storms somewhere else.
Artificial intelligence systems have big environmental costs but are also finding ways to save energy and water, cut emissions and make businesses more efficient.
Coal mines are notorious sources of acid mine drainage, but the orange sludge that threatens water supplies and wildlife also contains valuable rare earth elements.
Like living beyond your financial means, using more water than nature can replenish can have catastrophic results.
The EPA is changing how it assesses proposed regulations by dropping the monetary value of health benefits from its cost-benefit analyses. That misses a big piece of the picture.
Sinkholes are fairly common in Philadelphia due to aging water lines that leak or burst, causing the surrounding soil to wash away.
