Question

two important for waste management is nesseey

Answer 1

Human beings have been practicing primitive waste management techniques for thousands of years. Early humans simply dug a hole and buried their refuse and trash. This was an effective technique for these early people because their population was relatively small, and they did not produce as much garbage as modern humans do. Burying the trash helps to prevent bugs and
rodents from becoming a nuisance and spreading diseases.
In the modern world, humans cannot simply bury their trash. While primitive humans produced very little waste, and that which was produced would
biodegrade quickly, modern humans produce large amounts of waste, much of which is not biodegradable. Additionally, many types of garbage may be damaging to the soil, ground
water and surrounding habitat. To address this problem, modern waste management professionals place garbage in lined holes and use bacteria to help facilitate rapid decomposition
of the garbage.
