Desert Threats
Because of the lack of rainfall in the desert, plants take longer to grow, which leads to less animals and faster desertification which is a big issue facing our world. Current our deserts cover 1/5 of the world, but because of human activities deserts are expanding. Human activities that harm our deserts are, off road vehicles, they leave tracks in the soil for up to 2 decades, causing looser soil. Also animals that hide in the sand such as the sand viper can be hurt. Collectors continue to take precious cacti from the desert causing extinction, and less plants to hold down the soil. Other issues result from farming and mining, hunting, and development of the deserts.
All these activities continue to loosen desert soil. Sandstorms from deserts are now increasing. This is harmful because the dust particles in the air from these storms are small enough to enter your lungs, and cause major issues for humans. Dust is also being deposited in reservoirs, which causes more health concerns.
