Wet or Dry: Life's Mastery of Moisture explores how life thrives in Earth's most extreme water environments—lush rainforests and arid deserts—revealing universal lessons about adaptation and resilience. The book contrasts these biomes to uncover shared survival strategies: rainforest species combat flooding and nutrient-poor soils with drip-tip leaves and rapid recycling, while desert life masters water storage and timing, like cacti storing moisture in their stems or kangaroo rats surviving on metabolic water. At its core, the book argues that these adaptations are not just biological marvels but blueprints for sustainability in a climate-changing world.

Blending ecology, climatology, and anthropology, the book progresses from foundational concepts like photosynthesis and symbiotic relationships to real-world applications. It highlights how leaf-cutter ants cultivate fungi to detoxify rainforest plants and how desert root systems inspire water-efficient agriculture. Unlike single-biome studies, Wet or Dry uses stark contrasts to show how scarcity and surplus drive similar innovations in efficiency. The narrative avoids jargon, using vivid examples like fog-harvesting beetles and Indigenous cultural practices tied to saguaro cacti to anchor complex ideas.

What makes this work unique is its urgent, interdisciplinary lens. It challenges misconceptions—deserts as "wastelands," rainforests as "inexhaustible"—and connects evolutionary biology to human solutions, from drought-resistant crops to policy frameworks. By framing extremes as catalysts for creativity, the book transforms ecological insights into tools for navigating our climate future.
