The climate is changing because we are destroying the environment, and fighting climate change requires stopping and reversing this process. You can't have one without the other.
People are able to do something concrete about climate and environment if given the chance. Get them involved and show them that emission reduction is a meaningful, fun, and easy thing to do.
Industrialized countries use offsetting projects to reduce their carbon emissions. These projects transfer green technology to developing countries and help develop a low-carbon energy infrastructure there.
