Are you looking for different ways to save the environment other than the usual ones? I mean there's recycling, walking not driving, taking the train not the plane, composting, planting trees, having more indoor and outdoor plants, insulating your home, investing in solar panels, making works of art from garbage etc etc etc.
Interesting ways? Difficult ways!!!
Buy only local food for a week, then two, three, six?
Buy goods with no plastic packaging at all.
Do not buy anything new for a month.
Have an electricity free day.
Reduce your energy bills by 1% then 2% then 5% and give the savings to a green charity.
