Ecology > Economy
If our ecological framework collapses due to climate change then all of the ‘progress’ that we’ve made will mean nothing. Thinking about it in purely economic terms, environmentalism is a good investment because by maintaining a healthy planet you can continue making profit. Besides money is an abstract mode of exchange, hyper-accumulation of profits, making more money than you could ever spend therefore is illogical. Finally, the earth and its systems of weather/biosphere/species/habitat/vegetation regulation are physical, they have an absolute value that something such as money will never have.
