(C) degradation of renewable free access resources. (D) climate change. Answer C The biologist Geratt Hardin called the degradation of renewable free access resources as the tragedy of commons The tragedy of the commons is an economic theory of a situation within a shared-resource system where individual users acting independently according to their own self-interest behave contrary to the common good of all users by depleting or spoiling that resource through their collective action.
