Made by nature, well yes your right to a certian extent, but the rate of global warming has increased dramatically since the onset of industrialization.
Mankind is pumping billions of tons of greenhouse gasses into the atmosphere and that helps nature with global warming. altho most scientist in the world NOW know that global warming is real some still say its all bullshit.
But then again you could smash a turd and roll it in nuts and bake it and tell people its a turd rolled in nuts they will argue that its really a brownie.
I say go ahead and take a huge bite!
my contrabution to blobal warming is when i toke on my bowl i release a lil CO2.
