Trees Decay in the nether

So basically If you plant a sapling in the nether, the sapling will take twice as long to grow, and when it does grow, the wood will slowly turn into powdered wood and powdered leaves(basically if you shot something with a cartoon laser), and eventually decay entirely. If you break powdered wood or leaves, it drops nether powder(5% drop) its very easy to break, and doesn't require any tools.

Nether powder is gunpowder but better, makes a stronger tnt with a larger explosion radius and what not.
