re: #284 prononymous

Very good point. Along with composting and other techniques people can recover many of the excess nutrients they produce.

as a young Big Steve working for a major oil company in Los Angeles, I invented a process that eliminated over 1 million pounds of TOC (total organic carbon) out of the plants wastewater discharged per year. My name alone was on the patent. This process was adopted initially by the six refineries in my company and then was eventually sold across the industry. My guess is that my inventory has reduced the pollution load across the US by a half billion pounds in the last 20 years. So do I get a pass on using 10 grams of tri-sodium phosphate per week?
