In the air quality directive (2008/EC/50), the EU has set a target value and a long term objective value for ozone (O3) for the protection of human health. Target value: the maximum daily eight-hour mean may not exceed 120 micrograms per cubic metre (µg/m3) on more than 25 days per calendar year averaged over three years. Long term objective value: the maximum daily eight-hour mean may not exceed 120 micrograms per cubic metre (µg/m3) within a calendar year.

Use a toy library and if there isn't one in your neighbourhood, start one!
Instead of buying new toys, set up a toy library with your friends and exchange them. The variety of toys will entertain the kids and they will be used by more than one child thus reducing your impact on the environment.
