- Science fiction, like Frank Herbert's Dune, envisioned terraforming through life itself, highlighting the reciprocal dependencies of living systems at planetary scale.
- James Lovelock's Gaia hypothesis proposed that life actively regulates planetary conditions, not just adapts to them, forming a self-regulating system.
- Beavers are ecosystem engineers, modifying hydrology and geomorphology through dam construction, increasing groundwater discharge and creating wildfire refugia.
- Beaver Dam Analogues (BDAs) mimic natural beaver dams, encouraging beaver repopulation and converting human efforts into self-maintaining biological infrastructure.
- Bioswales effectively manage stormwater, reducing runoff and pollutants while recharging groundwater and mitigating urban heat islands.
- Rain gardens capture and treat stormwater, enhancing groundwater recharge and managing runoff more effectively than conventional lawns.
- Johads, traditional earthen dams in India, have revived rivers and raised groundwater levels, demonstrating community-led water management success.
- Oyster reefs provide coastal protection, water filtration, and habitat, with innovative restoration methods like Rapid Reef and Mother Reefs scaling up efforts.
- Mangroves offer significant storm protection and carbon storage, with drone technology accelerating large-scale restoration projects.
- Seaweed farming acts as a fast-growing carbon sink, with potential to reduce methane emissions when used in cattle feed.
- Nitrogen-fixing trees like Acacia improve soil fertility in drylands, supporting other vegetation through biological nitrogen fixation.
- Integrated farming systems, such as rice-fish-duck symbiosis, enhance productivity and sustainability through ecological design rather than chemical inputs.
- The Amazon rainforest generates its own rainy season through transpiration, influencing global weather patterns and demonstrating life's role in climate regulation.
- Reduced sulfur emissions from shipping have unintentionally increased global warming, highlighting the complex interplay between pollution and climate.
- Marine cloud brightening research explores replicating the cooling effect of ship tracks using benign materials like sea salt aerosols.
- Scaling biological geoengineering faces challenges like ecological mismatches, governance failures, industrial constraints, and political fragility.
- Industrial capacity, including cheap energy and automated production, is critical for deploying biological geoengineering at climate-relevant scales.
- Successful programs like Wageningen University's agricultural research face budget cuts despite high societal returns, underscoring the need for embedded physical capital.
