1. Use water-based paints. Rinse paint brushes and other equipment in an interior drain only. Reduce smog (low level ozone) by painting when temperatures are under 90 degrees.
2. Bike or walk instead of driving (Every 25 miles you don't drive prevents a pound of pollution)
3. Consider using solar energy in your house. Solar energy prevents water and air pollution associated with burning fossil fuels for energy.
i hope this helps u :)
