Like garbage today‚ this waste was either burned‚ tossed into waterways‚ buried‚ or dumped aboveground.

If the remaining 99% of the animals raised in factory farms in the United States were instead raised in a free range system the increase in resource demands would be incredible. For example‚ cows in todays factory system are raised on a supplemented diet of corn and therefore require no pasture land. If instead‚ all of the 30.2 million cows killed annually were raised on a natural diet of grass it would take over 60 million acres of pasture to accommodate the animals. That is a area of land roughly

Bismuth was discovered in the fifteenth century by a french chemist named Claude Geoffroy the Younger. At first his colleagues thought he was crazy‚ thinking that he had found lead or tin. But Geoffroy had distinguished it as a unique element. The name Bismuth comes from the word Wisuth meaning “white mass”‚ because pure Bismuth is white. When pure bismuth is mixed with lead‚ tin‚iron or cadmium the multi colored Bismuth is created. Bismuth falls under the pnictogen family. This family consists
