Hardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites（垃圾填埋场）.
Electronic waste（e-waste）currently takes up 5 percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank.They end up in places like Agbogbloshie on the outskirts of Ghana's capital,Accra.It is the biggest e-waste dump in the world,where 10，000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.
But Agbogbloshie should not exist.The Basel Convention,a 1989 treaty,aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries.The e-waste industry,however, circumvents the regulations by exporting e-waste labelled as "secondhand goods" to poor countries like Ghana,knowing full well that it is heading for a landfill site.
A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising：smartphones contain chemicals like mercury（水银），lead and even arsenic（砷）.Reportedly,one egg from a free-range chicken in Agbogbloshie contained a certain chemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority（EFSA）.Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all,since some of Ghana's top exports are cocoa and nuts.
Some governments have started to take responsibility for their consumers' waste.For example,Germany has started a project that includes a sustainable（可持续的）recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone,as there is an almost limitless consumer demand for hardware,especially when governments green policies are focused on issues like climate change.
Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair,reuse and recycling of hardware profitable,or at least cost-neutral.
