Sanitation Updates 
Tomatos thrive on urine diet is an excellent article. In China they used human excreta extensively for agriculture. I do not understand why India does not follow the example. Both urin and excreta can be used as a source of cheap fertilizer instead of burning fosil fuel which makes a heavy carbon foot print.
