"Why?" the girl asked.
"It's a simple reason," Wu Peng made an exaggerated gesture, "Now the ecological balance of the entire planet, after tens to hundreds of millions of years of evolution, has begun to tilt. And we humans want to maintain this already skewed ecological balance—it's not something that can be done in just a mere two or three years. Randomly destroying species or adding new ones will actually accelerate the tilt of this balance."
Humans would only continue to stay on this planet for a short two or three years, without enough energy or manpower to address this issue.
"Moreover, the evolution of the natural environment, while it has its historical rules, forcibly intervening doesn't really make much sense. Do you think the lives of the Riley people are important, or is it the lives of other species that are important? Or perhaps the species that will be born later?"
