You cannot love nature or your family if you feed them food that is full of dangerous chemicals. The vaishnava lifestyle is natural with a simple living and high thinking mentality. They offer everything they eat to God and prefer to use products which are in season, and that are both healthy and natural. This is the teaching of Bhakti rasamrita sindhu. There was no plastic or chemical fertilizer when Prabhupada preached, but Gandhiji could also see the danger of leading a toxic lifestyle. Growing organic food, maintaining cleanliness and not using plastic, which will end up in our holy rivers, will please Prabhupada and all mahatmas.
Srila Prabhupada was managing a large ecological community in Mayapur called Vraja-pattan, with many farmers being part of the effort. It was a place of meditation and had lakes called Radha-kunda and Syama-kunda and a replica of the Govardhana Hill. The production of food and flowers for the deity was the main use of the land, and growing them took a lot of time and energy from his intensive schedule. Therefore, he requested Vinod Babu, who later became Srila Bhakti Prajnan Keshava Maharaja, to take over the responsibility of farming and producing excellent produce. He set the example of ashram communities centered on ecological agriculture and animal protection.
