Earth and Human Activity

  1. Environment

    China exports pollution alongside goods

    Many companies have moved the plants that make their products to developing countries, such as China. But the pollution linked to making those products can travel around the world.

  2. Animals

    Birds versus windows

    Buildings in the United States can be deadly obstacles to flying birds. A new study estimates that as many as 1 billion birds die every year after colliding with windows. And low buildings — not skyscrapers — account for most of those deaths.

  3. Earth

    Mining metals amidst seafloor animals

    Miners may need to get their feet — and everything else — wet as they carefully seek out loads of copper and other valuable natural resources.

  4. Microbes

    Arctic thaw is spreading wildlife diseases

    Polar animals are encountering new, killer parasites as melting ice unlocks their access to new hosts.

  5. Animals

    First living fish leaves ‘endangered’ list

    Twenty-one years ago, a minnow facing a high risk of extinction was placed on the U.S. Endangered Species List. With help from scientists, the fish appears to have largely recovered. It’s the first ‘listed’ fish to do so.

  6. Life

    Caught in the act

    Scientists observe some evolutionary speed demons as they adapt over the course of just a few years to new environmental conditions.

  7. Animals

    Explainer: People can sicken animals

    Wildlife can sometimes become infected with germs shed by people.

  8. Chemistry

    Explainer: Ocean acidification

    Here’s why shellfish and other animals in the sea suffer when the ocean is forced to absorb too much carbon dioxide.

  9. Climate

    Watching our seas rise

    Satellites, coral reefs, ancient Roman fishponds and sinking cities help us understand how humans are changing sea level.

  10. Climate

    Dirty clouds change rainfall

    Scientists find a link between air pollution and extremes in rainfall.

  11. Animals

    Tiny earthworms’ big impact

    Invasive earthworms change North American landscapes, for better or worse.

  12. Climate

    Did Columbus contribute to a Little Ice Age?

    Scientist shows a surprising link between the explorer and a dip in temperatures.
