Are the changes caused by wind erosion of land in the high plains all due to human activity ? why or why not

No, why not? because the high plains is a relatively level high plateau, separated from the Rolling Plains by the Cap rock Escarpment. Elevations range from 3,000 to 4,500 feet above sea level.

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
