Beautiful Red Cactus Wallpaper

Cactus, highly adapted to the harsh desert environment, flourish in places where other plants cannot survive. Their survival is threatened by “cactus rustlers” who steal these plants for the profitable landscaping trade. Some individuals destroy cactus by operating vehicles off the road while still others use these ancient plants for target practice. Cactus plants probably grew in a tropical environment until about 65 million years ago when, in much of California, the climate changed from year-round rainfall to a pattern of dry summers and wet winters. Later, when the desert began to form as the Sierra Nevada and Peninsular Ranges rose and blocked rainfall to the eastern valleys, the cactus adapted to the dry, desert conditions.
Their beautiful blossoms, thick stems and unusual shapes attract thousands of people to the desert each year. Cactus, as a plant family, show variations between the individual species. Different varieties of cactus was used for food and medicinal purposes by Native Americans for thousands of years. The Cahuilla Indians spent the cooler months gathering wanted plants. They harvested the fruit of the beavertail cactus for its sweetness. The fruit was cooked in a pit with hot stones for at least 12 hours, and the large seeds were ground into a mush. When the flesh pads were young, they were cut into small pieces, boiled and served as greens. Cactus continue to photosynthesize because they have fixed spines instead of leaves. The green stems produce the plant’s food, but lose less water than leaves because of their sunken pores and a waxy coating on the surface of the stem. The pores close during the head of the day and open at night to release a small amount of moisture.
