See that mystical and beautiful forest? It's full of trash. Do you see those beautiful Sumatran Tigers? (Sumatran tiger is my favourite tiger, but they are the rarest tigers) There are only fewer than 600 left... Do you know IMPERIAL AMAZON parrot? Search them, there are only about 50 Imperial Amazon Parrots left. Put this on your profile, if you care about nature. I bet 99% you won't post it. Also, put #ICareOfNature to your status.

Tau (τ) is a much better constant than pi (π), as it simplifies many mathematical formulas and makes the radian angle measure system more intuitive. Tau is defined such that τ = C/r, which is more natural than π's C/D, this is because the definition of a circle relies on the radius, not the diameter.
