You don't need to be able to start a fire, when you keep the fire burning all the time. And you can do that, once you control the fire and figure out the difference between dry and wet wood.
Also humans are the dominating species on land since quite a while. Hunting certain species to extinctiom has certain effects on the local ecosystem and globally on the global climate. It all adds up.
But things surely changed in dimension since industrialisation.
- dekhn 3y agoPeople had fire in those times but it's extremely unlikely they produced enough CO2 to have an anthropogenic impact on the climate leading to large-scale temperature changes. I'm not sure what your perspective on this situation is but I think the case for modern anthropogenic climate change with deleterious effects is based on a wide range of different evidence, and a careful accumulation of facts and analysis. Simply pointing out that humans had fire 2Mya doesn't change the general conclusion about today.
- londons_explore 3y agoI suspect gr main change caused by humans >100 k years ago will be wiping out various species and starting fires in seasons and places where fires wouldn't normally start (eg. In places without dry lightning or volcanoes - the only two other ways fires naturally start)
