Increasing my Impact

There's a lot of talk these days about:

• reduce your carbon footprint
• leave the earth the way you found it
• tred lightly
• reduce your impact on the environment etc

While these are good (and I totally get what the intent is) why are we so concerned about leaving things the way they are?  Personally I'd like to increase my impact on the world in a positive way.

• support a family in africa with food and opportunity to thrive
• plant some trees in deforested areas
• help cook food for a local soup kitchen
• go across the road and help your neighbour build a shed
• invite someone over for Christmas dinner that's not part of your family

Increase your impact.
