Answer 1

I think the best race will be ....that the participants are told to collect  the waste polithene bags  along  the way all over they pass through ...and dump it to the dumping ground or some place where its recycled.

Answer 2

I think a good amazing race task would be a  piece of land with a lot of aluminum cans that need crushing.. it would be easy and inexpensive to find the cans, and I'm sure the recycling center would be glad if they were crushed. Or taking newspapers from a recycling center and having to tie them in bundles and haul them to a truck....
