Human excretion can reduce global warming

Can you imagine if the human excretion can help us to reduce the global warming?
If you can, then it means you have a really interesting imagination.
If you can't, then it means you have to.
In fact, the human excretion really can have a great advantage for us to reduce GW itself.
Based on the what has been said by the founder of Sulabh International Social Service Organization, Bindeshwar Pathak, an organization that is dedicated to make a sanitation, he said that he has been developing a toilet with a system to change human excretion becomes biogas organically. After that, it will be changed into electricity or fuel to cook. For the urine, it will also be changed into fertilizers. He claimed that he has successfully implemented this eco- friendly toilets in Kabul, Afghanistan.
What an interesting real imagination! :)
