The first thing I want to argue is that the former civilization is running into pretty profound crisis in its relationships to the rest of nature., which we do and what we have depended on for survival and for flourishing. And this is the most widely and well-recognized in relation to climate change. CO2 emissions, greenhouse gas emissions. But I want to argue the certain dangers in the way that has been presented as the central question that we have to address. Because ifs interlocked with a number of other crises that is most noticeably as the crisis in access to fresh water, crisis in access to food, biodiversity loss on a huge scale., and associated problems of human in equality not just in a common world, but actually in the kinds of environmental resources, and pleasures that I can enjoy. So all those together, have to be looked at an interconnected set of really deep profound crisis.
