I think the whole thing is a money issue.
You want to be responsible...how about going out one weekend and helping a group plant some trees somewhere.
How about signing up for adopt a highway and helping clean up some litter.
If you are building a business or home, think about doing it with some materials that are environmental friendly.
Think about helping the recycling effort by separating your garbage and taking plastics, papers or aluminum to recycling centers.
Buy recyclable or environmental friendly products.
Donate money or time to good, what YOU consider good, environmental causes.
How about doing things of that nature.
But that is just my take...Just don't trust that whole carbon credit thing where you go to someone else and never know what is done afterwards.
