Climate change is a 'natural' process now occurring ~10 times faster than the average rate after an ice age. Extinction is 'natural' but is now occurring 1000X faster than in past eras (apart from mass extinctions). Biological invasion is now at rates 100000X prehistoric levels of spp colonisations.

"even small changes help", and it's not just CO2... big for land use, fertilizer, pesticides, water quality.
Simply reducing beef and lamb consumption to one serving a week -- as recommended by EAT-Lancet -- could reduce emissions by almost 3 billion tons CO2-eq. The equivalent of all of Russia's annual emissions.
