A Correct answer
Explanation

The recommended way to dispose of human waste while trekking in remote areas is to bury it in a shallow hole at least 6 inches deep. This helps prevent the spread of disease and contamination of water sources.

Multiple choice

Which of the following is NOT a sustainable practice for disposing of food waste while trekking?

  1. Composting food waste in a designated composting area

  2. Burying food waste in a shallow hole at least 6 inches deep

  3. Leaving food waste in the natural environment for animals to consume

  4. Carrying food waste out with you and disposing of it properly at a designated waste disposal site
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Leaving food waste in the natural environment can attract wildlife and lead to conflicts between humans and animals. It can also contaminate water sources and spread disease. The best way to dispose of food waste while trekking is to compost it, bury it in a shallow hole, or carry it out with you and dispose of it properly.

Multiple choice
