Answer:
Ventilation and shading can help control indoor temperatures. Ventilation also helps remove or dilute indoor airborne pollutants coming from indoor sources. This reduces the level of contaminants and improves indoor air quality (IAQ).
These basic properties are vital to the survival of life. Water's polarity and surface tension makes it a powerful solvent for sugars, amino acids, and proteins; water can easily hold and transport substances necessary for life within and outside of living things.
I believe the answer to this is Genetic Diversity.
