In tropical areas, a survival kit may have mosquito head netting, additional insect repellent, anti-fungal cream, a machete, water purification tablets, foot powder, matches, a flint strike, a compass, a wire saw, a space blanket, medical equipment (gauze pads, elastic gauze bandage, antiseptic creams, anti-malaria tablets, anti-infection tablets, bandages, etc.), salt tablets, a fishing kit, snare wire, extra socks, a candle, a signal mirror, flares, a sewing kit, safety pins, tinder, tape, a whistle, and rations.
Adherents of the back-to-the-land movement inspired by Helen and Scott Nearing, sporadically popular in the United States in the 1930s and 1970s (exemplified by The Mother Earth News magazine), share many of the same interests in self-sufficiency and preparedness. Back-to-the-landers differ from most survivalists in that they have a greater interest in ecology and counterculture. Despite these differences, The Mother Earth News was widely read by survivalists as well as back-to-the-landers during that magazine's early years, and there was some overlap between the two movements.
