Answer:
Why are pits lined with plastic sheets at modern landfill sites ?
Ans. Since plastic is very strong and doesn't decompose or break down easily, It is used in landfill sites due to the fact that it reduces leakage of various materials. Since plastic is very strong and doesn't break easily, it prevents the seepage of water through it into the soil, thereby preserving water.
