LNT Answer 6

Purists would choose "d" here, arguing that all non-native substances should be kept out of the ecosystem because harmful insects or other organisms may hitchhike, and native fauna may become ill or lazy from repeated free meals. On the other hand, most folks see nothing wrong with choice "c," scattering certain fruit scraps well off the trail (apple cores, for example, but not orange peels, which break down very slowly). However, since few people appreciate sitting in someone else's crumbs and peanut shells, when in doubt, pack it out.
