Water Purification - Clay, coffee grounds, and manure...

A handful of clay, yesterday

[haribol]

Sounds good! Cow dung has been used for fuel for thousands of years in vedic civilisation.

'There are so many facilities afforded by cow protection, but people have forgotten these arts. The importance of protecting cows is therefore stressed by Krsna in Bhagavad-gita (krsi-go-raksya-vanijyam vaisya-karma svabhavajam [Bg. 18.44]). Even now in the Indian villages surrounding Vrndavana, the villagers live happily simply by giving protection to the cow. They keep cow dung very carefully and dry it to use as fuel. They keep a sufficient stock of grains, and because of giving protection to the cows, they have sufficient milk and milk products to solve all economic problems. Simply by giving protection to the cow, the villagers live so peacefully. Even the urine and stool of cows have medicinal value.'
Srila Prabhupada
 [Srimad-Bhagavatam 10.6.19 Purport]

"According to Vedic civilization the cow is to be given special protection. Why it is recommended for the cow? It does not say of other animal. When animal killing is required according to Vedic civilization, those who are meat-eaters, they are allowed to kill some insignificant animal like deer, goat, pigs. It is for the animal eaters, not for all. But if one is bent upon... And there are persons, they want meat-eating. So for them these unimportant animals are recommended. But cow is very important animal. You get from its milk so many nutritious food. So apart from religious sentiment, from economic point of view, cow-killing is not good. And from moral point of view it is not good because you drink cow's milk, so cow is your mother."
