E-waste is a problem and its growth will be obvious if you look around your own home. You’ll likely find broken or unused mobile phones, non-functional cordless phones or handsets, routers with antennas in tatters, bricked routers (i.e. those that you tried to install Linux on, or tried to update the firmware, but something went wrong,) an old TV in the basement and so on. Some reasons for the growing volume of these is that electronics are literally dirt-cheap these days (some of those cordless phones and routers come for $20-$30 or less.) Besides, many things become obsolete very quickly. Of course, to a large extent this obsolescence is well-planned. The corporations selling you electronics want to keep selling to you.
E-waste often contains a number of toxic and/or carcinogenic substances such as lead, mercury, cadmium, polychlorinated biphenyls and more. If these make it to landfills then eventually the toxins can find their way into food and water supplies. Therefore, it is not surprising that this proliferation of e-waste needs to be controlled. In some ways, here is an example of a government actually acting much sooner than they have in many other situations (consider the history of other toxic waste.) That certainly is a good sign.
