If you’re on a trekking or expedition, you’re likely in a national park or a protected area due to the sensitivity of its ecosystem.
Glaciers are natural phenomena that, kilometers below, will melt and provide water and resources to villagers, animals, and crops long after you have left.
Protect the local fauna and flora and do not take ice from the glaciers to heat water.
Do not urinate, defecate, or throw contaminants (trash or medications) into the rivers you come across. Instead, follow the instructions of the local population to know how to dispose of waste properly.
Minimize pollution and be mindful that others will use the resources you might otherwise waste.
