The environment is our word for the place in which we live. Pigs are naturally clean creatures, in their natural forest environment – they only get smelly when humans cram them into an unnaturally small space. Locusts clear the very ground of every edible thing when they periodically hatch and swarm, there's nothing left for next time unless their progeny hide for a number of years waiting for their environment to recover sufficiently. As humans we have a brain capable of realizing these things, seeing the parallels with our own situation, and making positive or negative choices which affect the way we use or abuse our environment. We are clearly powerful enough to make lasting and substantial changes to the world around us. Allegedly we are intelligent enough to make informed decisions on how we interact with our environment. Being naked is one positive step in our dealings with nature. It's not complicated: we use less textile materials, dyes, transport mechanisms, slave labour and cleaning chemicals, when we use less clothing. To do something positive today, about tomorrow, get naked, how much simpler can it be?
