I calculated that i live on ecological dept

http://footprintnetwork.org told me that i need 4,7 hectares of land to support my lifestyle.
2+ hectares is to support heating our flat.
If everyone lives like me we would need 2.6 planets of regenerative capacity to cover the lifestyle.
So im living on the ecological dept :-(

Im curious what is the best affordable ways to reduce this footprint. Or where to put money so i help raise lands regenerative capacity or energy/food capacity?
