WWF works to sustain the natural world for the benefit of people and wildlife, collaborating with partners from local to global levels in nearly 100 countries.
Climate is the most important predictor of butterfly species distribution. Butterflies have been documented shifting their range toward the poles and to higher altitudes.
African elephants need up to 300 liters of water a day, just for drinking. As rainfall patterns change, humans and wildlife are competing for diminishing sources of water.
As winters get warmer and shorter, moose populations in the northern US are declining due to tick infestations.
Responding to warmer spring temperatures, plants are flowering earlier than they used to, resulting in a mismatch between peak plant growth and the animals that depend on them.
Oceans have absorbed much of the planet’s warming since the Industrial Revolution. Warming oceans are causing corals to expel the algae living in their tissues and turn white—a phenomenon known as coral bleaching. Over time, the corals can die off and no longer offer a healthy ocean habitat for the species that rely on them for feeding and protection.
