Around 1,000 meters hydrostatic pressure rises so high that it produces crushing forces on the body and organs, causing rapid physiological failure and making the environment lethal to unprotected humans.

Play releases pleasure-related neurochemicals and provides low-risk practice with objects and movements, which strengthens neural connections that later support creative object use and novel problem-solving.

In the last ice age, massive meltwater floods diluted North Atlantic surface salinity and stalled deepwater sinking, which reduced heat transport and triggered rapid, widespread cooling across the northern hemisphere.

Stressed or diseased trees send chemical warning signals through mycorrhizal networks, which causes neighboring trees to upregulate defense enzymes and become more resistant, effectively creating a communal immunization effect.

Both animals and submarines have depth limits because biological systems fail under extreme pressure (oxygen use and tissue tolerance) while engineered hulls collapse when materials reach their strength limits.

The amygdala attaches emotional valence to places and sensory cues, so perception is shaped by prior feelings which then bias the bird's behavioral responses toward approach or avoidance.

Mother trees preferentially allocate more carbon to genetically related seedlings because they can direct resources through fungal links to kin, especially after injury, effectively passing support and fitness benefits down their genetic lineage.

When a bird associates a person with threat it emits scolding displays that others observe and copy, causing avoidance and targeted scolding of that human to spread socially and persist across individuals and generations.
