3/ DISPOSE OF WASTE PROPERLY
Leave nothing behind: everything you bring with you must go back with you. This also applies to biodegradable waste. You are not necessarily familiar with the ecosystem around you and an apple tree grown from your apple core is perhaps not the best idea. Always bring back your toilet paper and hygiene products in general. If you are on a day hike and desperately need to ‘go’, the best thing is to dig a latrine to a depth of 20 cm , more than 70 metres from your basecamp and fill and conceal the hole when full.
Finally, water is precious, do not pollute rivers. Empty your water, which must be devoid of chemicals, more than 70 metres from a stream. Use biodegradable soap. There are some very compact, multi-purpose brands for washing dishes and personal care.
