As well as the usual cancer-causing and sterilising waves from mobile phones, Apple's iPhone has the added bonus of containing hazardous compounds. Phthalates in the headphone cord are known to interfere with sexual development. Brominated compounds make up 10% of the iPhone. They create dioxin when burned, which causes cancer (there is no known 'safe dose' of dioxin) as well as severe reproductive and developmental problems.
In short, it's a dangerous bastard and when you feckers throw it away, you're going to be contributing to the downfall of the human race. An over-reaction? Not in the slightest. You only have to look at rising cancer rates across all age groups (especially the young) and rising fertility problems.
That's all aside from the usual mobile phone emission problems.
The Greenpeace report can be found here and you should Google all of the materials they found. Lawsuits are already beginning. And rightly so. You should know about this. You should care. Every single one of you.
