my most recent (which i'm not finished with yet) is "a sand county almanac" by our nations foremost and possibly first true ecologist, Aldo Leopold. his descriptions of wildlife, wild lands, and how they are intertwined are both rich in his descriptions, and alarming in his prophecies of the dangers of neglecting them. he touches upon topics relevant even today by pointing out (even then!) how many "sportsmen" try to buy "woodsmanship" by purchasing the latest/greatest technotoys instead of learning from the past. God only knows how many tears he would have shed over todays fish finders, "crossbows", GPS, trail cameras, laser range finders, the abusive and flagrant misuse of atvs on public lands, and the sale/destruction of OUR public lands by those prostituting them for the biggest bankrolls...
