The latest from my Scientific American series, East of Siberia:
THE TEMPERATE RAINFORESTS OF PRIMORYE become dense and green in summer, a vastness lost on those within it. Visibility can drop to almost zero along shrub-crowded game trails, where dew-drenched grasses cling like needy toddlers and spider webs tangle in the unshaven faces of those pushing through. Animals, resting nearby in the daytime heat, crash away unseen, and a discordant symphony of birdsong pulses from the canopy. Everything is immediate and aromatic; a box packed tight with vegetation, dirt, sweat, and humidity.
Not the kind of box you want to be in with a tiger.
