That humans will impact the planet is a certainty. Like all species, it's constantly "screwing" the environment. The missing link is that, in turn, the environment "screws back". This exogenous will force humans into adaptation - only failing that comes the extinction scenario. So it's not like we have a choice. Unless the entire species subscribes to nihilism (which I doubt it's at our core, or we wouldn't be here today), we have to adapt.
