The term "tipping point" best characterizes the moment in time described by the environmentalist. It refers to a critical threshold beyond which a system undergoes an abrupt and potentially irreversible change. In this case, it would be a change in the global ecosystem that would make it unable to sustain life. The other options may also be used to refer to a critical moment, but do not convey as much the idea of a sudden, irreversible change.
