About of Much Use to Planet Earth as a Giant Asteroid?

Phoebe Weston provides an account of the thousands of years of damage to the Earth's biodiversity by humans (https://www.theguardian.com/environment/2022/nov/25/cop15-humans-v-nature-our-long-and-destructive-journey-to-the-age-of-extinction-aoe). Weston points out that humans are now suspected of causing, by their unsustainable hunting, the pre-Pleistocene extinction of megafauna (large mammals and birds). Our species then appears to have turned in multiple locations to agriculture and animal domestication, to deal with the consequent food shortages. Agriculture and domestication have had, however, further negative impacts on biodiversity. Weston reiterates that 'humans treated nature as an inexhaustable resource for too long'. This was (and is?) especially true of the folk involved in the so-called European expansion. Indigenous peoples mostly tended to live within the limits set by nature. Around 90% of indigenous populations were, however, destroyed in the European expansion. Exploitation has become the name of the game. Weston hopes Cop15 (in Canada) will alter our understanding of the history of human impact on biodiversity, producing better and more effective protections. This, however, may be an optimistic 'reading of the runes'. The reason that the modern era is dubbed the Anthropocene is that humans are currently causing a mass species extinction. Indeed, the cumulative impacts of human activity are probably worse than that of the giant asteroid strike that wiped out the dinosaurs (and many other species). Changing the attitudes of humans in time to prevent environmental collapse, ain't going to be easy. Self-interest always seems to trump collective responsibility/ stewardship.
