Other way around. By focusing on biodiversity preservation we increase the robustness of the ecosystem and stop the dominoes from falling. Removing biodiversity cascades through the whole ecosystem and accelerates climate change. Also once bio-diversity is gone it's impossible to get back but we can always invent technology to extract CO2 from the atmosphere. Remember most of the species we're losing we don't even know they exist.
