China has long experience with large-scale projects that aim to manipulate the environment,
beginning with the ancient Great Wall and extending up to the modern Three Gorges Dam. They
intend to follow a similar grand course with cloud seeding that may become a permanent policy
as long as climate change and drought persist. This of course may last decades or hundreds of
years. The only cost-effective means for undertaking such a long-term program is through the
use of drones (more on this later).
