Hi @louisbettong, great post, followed you, i also did a post on global warming if you want go check it out.
That story of your computer is the classical model of neo-capitalism, why not make cellphones or computers that will last 20 years? It would save alot on the ecological footprint, but the company that make the products would not make profict, so for them is make new things that go obsolete fast, so you buy new ones!!
Peace
