Essay. We all know that in the current world there are lots of environmental problems: pollution, global warming, climate change. However as time goes by, problems increase with all the innovations of our century; and for this reason we worry about the problem of discarded electronic devices or e-waste more every day. "Electronic waste" may be defined as discarded computers, office electronic equipment, entertainment device electronics, mobile phones, television and refrigerators. The fundamental problems, derived by this kind of waste, are the presence of toxic substances for the environment and the fact that e-waste are not biodegradable. The diffusion of electronic devices implicates a risk of abandonment in the environment or in landfills associated with ground pollution, atmospheric or water pollution and consequences on the human health. For example, Guiyu in the Shantou region of China is a massive electronic waste processing community. In the mid-1990s Guiyu transformed into an e-waste recycling center involving over 75% of the local households. Uncontrolled burning, disassembly, and disposal has led to a number of environmental problems such as groundwater contamination, atmospheric pollution, and water pollution as well as health problems including occupational safety and health effects. However Guiyu is not the only problem. Silicon Valley is a region in the Usa where the world's largest high-tech corporations have home. In the same way of Guiyu, it is one of the most poisoned community: IBM's own data revealed that its workers making computer chips had 40% more miscarriages and were significantly more likely to die from blood, brain and kidney cancer. Under these circumstances we should find a solution: the most common solutions concern the donation of electronic devices in good conditions to a local family, friend, school, or nonprofit foundation or the alternative is the recycling in some specialized center. In my opinion, the recycling is the better idea but first of all we should sensitise citizens about the problem with an advertising campaign and we should encourage the partecipation at the process of recycling with a system of refund when citizens take e-waste in the centers and a penalty if citizens do not respect the system.
