With pending termination of a national forestry act, The Indiana Forest Alliance is advocating protection and reforestation.  

Trees, it says, begin to solve the problem of climate change because they remove offending particles from the air.  Urban forestry both lowers temperatures and raises home values.  

And a program of classified forests, areas of 10 acres or more, privately held, pay taxes on only $13 of assessed value if owners protect the trees.
