TerReForm had continued anyway, through ad hoc cooperation between scientists and labs straddling the Red/Blue borders. Twenty-three years later, however—practically as soon as New Earth’s atmosphere had become breathable without artificial aids—had begun the War on the Rocks, a struggle carried out partly in space but mostly on the still-nude surface of New Earth. This had been terminated in 4895 by what was now called First Treaty, which stipulated among other things how subsequent TerReForm activity was going to proceed. It had thus paved the way for the Great Seeding, which was responsible for the trees that Kath Two had been flying over this morning. In subsequent decades, larger and larger animals had been set loose on the surface as part of a planned program to jump-start whole ecosystems.
