people bury garbage and ? in soil and spray ? on soil to kill pests.?

Answer 1

lime on the waste, I believe. A neighbor had an outhouse, and that is what they used.

Answer 2

toxins or chemicals...bad bad, bad. Yo! polluting people wake up..it all ends up in our bodies too, when you or a loved one dies of cancer it will hit you where it hurts. Throwing away trash (that could be recycled or simply reduced) and using chemicals may be easy and cheap, but in the long run the price is too high.

Answer 3

You can get rid of pests by using pest control.
