Answer 2

Heyyaaaa...

Ur answer for 1st question :

           # Untreated human excreta is obviously a health hazard.
           # Becoz it causes land pollution and underground water pollution which contaminates the sources of waters, from which people get water for their daily uses like drinking, cooking etc...,
           # This contamination causes diseases like cholera, typhoid, hepatitis and can even lead to death...

And for 2nd question..

             # Plants, oil, solvent and insecticides should not be thrown into drain.
             # Becoz fats and oil can harden and block the pipes leading to a decline in its filtering ability..Likewise, chemicals in insecticides may kill the microbes that purify the water..Plants may choke the drains leading to the inability of free flow of oxygen...

And last for 3rd question..

              # Vermi composting toilets are needed becoz it saves lot of energy and water..
              # And it the material from composting toilets can be used for garden and also as a manure in fields..
