Actually that looks like the contents of one of those tech recycling barges. We ship a bunch of this stuff to India which is then repurposed or recycled. That system is a driving factor behind India's emerging tech market too. Also the knowhow generated by technological progression trickles down to places like Africa, which is experiencing a huge uptake with tech consumer devices and services like mobile phones, wifi etc. So there are upsides to wealthy western countries never being satisfied with what they have.
On the ecological aspect, It's actually illegal in some countries to throw a phone/tablet into the garbage when it's broken because of the rare metals it contains, so recycling is encouraged and works in theory. Of course most of us are too lazy to drop our stuff at the recycling banks, or ignorant of the laws in the first place. So when there's a shortage of precious metals we can just say, invade North Korea which has the largest untapped precious metals reserve in the world right now. :/
