There are no truly environmentally friendly toys. There are toys which are -less- harmful to the environment to produce than other toys. This can be due to the material (it lasts longer, it can be recycled), the production (harmful ingredients are not used in the manufacturing process), or the energy input (high efficiency motors, rechargable). However, having a toy that is rechargable is still not "green", as the energy to charge it must come from somewhere and most power plants do not use renewable energy.
