The meaning of Joshua Tree tattoo is mysterious and powerful. Joshua tree, which grows in the desert area of southwest North America, has appeared on the earth since the Pleistocene 2.5 million years ago. Its history is longer than that of mammoths. But a new study shows that without strong action to control global warming, this ancient tree species may become extinct by the end of this century.
Joshua Tree National Park in the United States is named after this plant with leaves like short knives, which attracts millions of people every year. Some Joshua trees can survive up to 300 years. One of the reasons is that they can store enough water to survive the dry season. However, small trees and seeds do not have such strong water storage capacity.
