This picture is from the Sonoran Desert in the state of Arizona, USA. It's a saguaro cactus. A saguaro cactus can grow between 40 and 60 feet tall! It is the largest cactus in the US, and a full grown plant, when fully hydrated, can weigh more than 4,000 pounds (more than 1,800 kilos)!
The Sonoran Desert is struggling with pollution, and the ecosystem is being disturbed by encroaching development. Much of the native landscape is very slow-growing. A 10 year old Saguaro Cactus might be only 1.5 inches tall! Because of this, it takes a very long time for this eco system to recover from disruption.
