Abstract: Macro-engineering involves the large-scale modification and manipulation of natural systems for the benefit of mankind. The primary goals of some Earth-based macroprojects described in this book are power production, land reclamation, food production, climate change, environment, water, transport and coastal protection. Other Earth or space projects considered here have a more futuristic ring, but our present-day technical skill makes their realization possible. Earth-based macroprojects usually combine different aspects and aims. They have a major impact on the ecology of a region and the inhabitants' means of living (like tourism, fishing, shipping). Its effects may be felt worldwide, like the rise in global sea level after the damming and evaporation of large ocean gulfs for power production, or the change in climate following the regional reduction of solar insolation.

Abstract: Weathering and subsequent precipitation of Ca- and Mg-carbonates are the main processes that control the CO2-concentration in the atmosphere. It seems logical, therefore, to use enhanced weathering as a tool to reduce rising CO2-levels. This can be applied as a technology, by reacting captured CO2 with olivine or calcium-silicates in autoclaves. It can also be applied extensively, by spreading fine-powdered olivine on farmland or forestland. Measures to control the CO2-levels of the atmosphere will be adopted more readily if they also serve some broader economic goals. An effective strategy for CO2 control will require many parallel approaches simultaneously.
