Its surface is forever changing as powerful forces inside the planet pull and push on the crust above, building mountains, tearing apart continents and constructing whole new pieces of land. Surrounding it is an atmosphere of gasses, which provides organisms with life-giving oxygen and produces our weather (with a little help from the Sun). Our planet may appear large, but it is still quite fragile. Changes to our climate over the last 150 years have threatened many habitats around the world, endangering the species living there and bringing many of them to the verge of extinction.
