🌿 Liquid Trees: Microalgae Photobioreactors and the Quiet Art of Urban Breathing
From section: 🌳 Liquid trees and living trees: different roles in the same landscape… These analogies are not standardized measurements. They depend on the reactor design, culture conditions, operating period, carbon source, maintenance, and measurement method, as well as the species, age, health, climate, and growth rate of the trees used for comparison.

☀️ Sunlight, Skin, and the Quiet Alchemy of Vitamin D
From section: ⚖️ Natural limits and self‑regulationVitamin D status therefore depends on more than the amount produced in the skin. Dietary intake, supplementation, metabolism, age, and other biological factors can also contribute. Beyond these internal controls, familiar external barriers such as glass, clothing, and sunscreen alter how much UVB reaches the skin.
