Tight-knit human social networks create resilience because members exchange care, assistance, and emotional support when someone weakens, functioning analogously to how organisms exchange resources and signals in ecological networks to sustain the group.

Diving beyond about 100 meters risks fatal decompression sickness because rapid pressure changes force dissolved gases (mainly nitrogen) out of solution into bubbles that damage tissues and blood vessels.

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.

Because the weight of the overlying water column produces compressive force that scales with depth, pressure at intermediate deep-sea levels can be enormous—so intense that vivid analogies (e.g., a polar bear on a quarter) help convey how much force is exerted on small areas.

Converting diverse old-growth into monoculture plantations and removing companion species disrupts mycorrhizal support networks, which increases disease spread and accelerates tree decline because trees lose mutualistic protections and nutrient-sharing partners.

Because ocean currents and winds depend on many linked factors (temperature, salinity, wind patterns), changing climate boundary conditions can push the coupled system into qualitatively different states, producing complex and partly unpredictable shifts in circulation.

Removing seemingly competitive species like birch breaks mutualistic fungal and nutrient exchanges in the mycorrhizal network, which reduces tree health and undermines the overall resilience of the forest.

Hydrostatic pressure increases with the weight of the water column, so at hadal depths (around 6,000 meters and below) pressures reach roughly 1,100 times surface pressure, producing crushing forces that would destroy unprotected objects or organisms.
