All of these topics are related because they all tie into the problems caused by increased consumption that is encouraged by the mainstream way of living. To take the example you've just mentioned, while Amazon may be more eco-friendly per transaction, as a whole it encourages much more consumption through the convenience the service brings. Somewhat similar to the Jevons paradox. The point is that the cost of the mainstream tends to be distributed in a long term and systemic way, (for instance Amazon becoming an extraordinarily powerful monopoly, or the environment slowly reaching a critical threshold) which makes preventing them necessary but extremely difficult to do. Not to mention that the advantages of our system are also undeniable and more visible.
