What are social controversies surrounding computer engineering?

You could possibly take on the issue of recycling of old computers/technology. Technology is advancing so quickly, and computers/monitors/phones/etc. are replaced so often that the old ones are too abundant and contain too many exotic materials to place them in landfills, they would do too much damage to the soil and ground water. They should be recycled, but a widespread and environmentally responsible way to do it has not been developed.

Just an idea. Obviously you would have to do a little more research.
