What steps or practices are farmers using to improve soil health?

They are not using as much or any pesticides, which is used to get rid of bugs that eat their crops, yet harms humans at the same time. Another way to make sure the soil stays healthy it to keep growing plants and crops. Usually when soil is left idol for too long, it will become dry and useless.

Explanation:

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

the cost of mining is extremely low compared to the money earned from mining, creating income to improve the environment.
