I know for many of us the most annoying thing while out on the fells is to find litter specially places popular among walkers. I don't take bananas when out but do take oranges and apples. I don't throw orange peels but been told apple core decomposes quickly and okay to be left in the wild and actually doing nature a favour. What do people think?

Also when nature calls, what's the best way to decompose human waste? Does it take long for human waste to decay?
