During a survival scenario, what is a common reason for not using natural materials to construct a shelter?

Using natural materials to construct a shelter during a survival scenario often presents challenges regarding their weatherproofing capabilities. A key concern is that many organic materials—such as leaves, branches, and grasses—typically do not provide adequate protection against rain, wind, or cold temperatures. When exposed to the elements, these materials can become waterlogged, lose structural integrity, or allow drafts to penetrate, ultimately failing to keep the occupants dry and warm.

Consequently, while natural materials may seem like a suitable choice for shelter construction, their propensity to lack effective weatherproofing makes them less reliable. Survivors must weigh these factors carefully and consider alternative options that may provide better protection against environmental conditions during a survival scenario.
