Many may or may not have heard of the sustainable food growing technique called Aquaponics. Aquaponics refers to any system that combines conventional aquaculture with hydroponics in a symbiotic environment. Where you grow your own fish and use their waste water which is nutrition for the plants. There’s a couple in Goa doing great with regards to this field, their name is Mr and Mrs Peter Singh. I think each individual should try to grow their own food and help the local community as well.
