Why the ocean is actually our best long-term bet as a species
For long-term species survival, the ocean presents a compelling, empirically validated alternative to terrestrial or extraterrestrial habitats. Unlike land, which experiences frequent and disruptive shifts, the deep ocean exhibits remarkable stability, having maintained consistent conditions for hundreds of millions of years—as evidenced by ancient species like the coelacanth. This longitudinal resilience, coupled with its vast buffering capacity, suggests the ocean represents a proven ecological system.
Does anyone know a cheap way for students in middle school to test for dissolved oxygen levels in water?
Middle school students exploring nutrient pollution’s impact on ocean health can effectively model phytoplankton blooms and subsequent oxygen depletion.
