If you have a buddy who has been letting you know how much more environmentally conscious he is because of his hybrid, tell him to think again. Hybrids like the Prius uses more rare earth elements (REE) than any object in the world. Neodymium and lanthanum, used in a hybrid's batteries and electric motor's magnets, could become extinct in the near future.
With REE used in fiber-optic telecom cables, military gear, computers, etc. hybrids could create a lot of non-ecofriendly situations.
