But we have. Holocene extinction started thousands of years ago. That's not a controversial thing at all.
- labster 5y agoIt’s still debatable how much of the early Holocene extinction was anthropogenic and how much was climate change or even predation. At least in terms of the megafauna like wooly mammoths and New World horses. Once state-organized civilization kicks off, consensus is that it was largely anthropogenic, even if it’s just us transporting diseases and pests around.
- jhgb 5y ago> or even predation That falls under "anthropogenic", too. Humans tend to eat stuff a lot.
- PaulDavisThe1st 5y agoI think the paper wants to make a distinction between affecting "earth systems" and human instigated ecosystem transformations such as the Holocene extinction.
- jhgb 5y agoWhatever "earth systems" means to you will be definitely affected by massive ecosystem changes as well.
