Why cacti are not widely planted in the desert?
The purpose of greening is not to look green, but to solidify soil and water, cactus can not achieve the role of solidifying soil and water.
Cactus plants are native to the tropical and subtropical regions of North and South America. Most of the deserts in our country are in the north, and the cactus can not survive because of the cold winter. And although the cactus is tenacious, it is difficult to survive in the special environment of the desert. And it is very difficult for a real large desert to be planted artificially, which is not so easy as expected, especially when there is a sandstorm at night, not to mention cactus, even people are dangerous. Therefore, this is impractical behavior.
Besides, the cactus can't change the soil structure or anything. Just protect local lichens and shrubs, save agricultural water, and let seasonal rivers flow down. If we really want to fundamentally afforest the desert, we must change the current climate pattern and increase the precipitation in this area.
