By protecting critical habitat for threatened turtle species around the globe, the TC has been able to address the effects of climate change on turtles in two significant ways. First, by protecting wild, functioning ecosystems, we maintain vital carbon sinks that keep CO2 out of the atmosphere. Secondly, the more critical habitat we protect, the better we can ensure that there are sufficient refugia for populations to utilize as ecosystems become altered by climate change. To date, the TC has protected well over 60,000 acres (24,000 hectares) of land.
