The oldest known trees are thousands of years old. The ancient plants have witnessed the rise and fall of multiple civilizations.
Galápagos National Park is an ecological treasure trove, a biological hoard guarded fiercely by conservationists. Visitors to the islands must abide by the park’s rules, which include not taking anything from the wilderness—or leaving anything behind.
A miniature desert blankets 40 acres of land just a stone’s throw west of Freeport, Maine. An uncanny contrast with the state’s sweeping trees, the dunes (dubbed the “Desert of Maine”) are a geological curiosity—and Mother Nature’s way of reminding us tha

The story of the Macquarie Island ecosystem may remind you of the song about the woman who swallowed a fly. The island was exploited mercilessly, but various plans to repair the damage had their own unintended consequences. Introducing a non-native specie
Every once in a while, an environmental disaster makes big news, but the effects remain years after the headlines have faded. Here are six stories of what human activity did to mess up Mother Nature. 1. Mossville,
We've all heard about the dangers of global warming and climate change. It's going to make the oceans rise, drown our cities, kill plants, cause hurricanes and ruin the Earth for our grandkids. But that's all secondary to the real effects of global warmin
