It’s almost Earth Day and some of the activities that get attention this time of year involve cleaning up litter or planting trees. While there are ways to help the environment every day of the year, you may want to consider an activity that goes beyond recycling cardboard or composting in your local community.

Montana is home to 339 environmental organizations, according to the nonprofit metrics website Cause IQ. Of those organizations, some focus on water, others on conservation, and quite a few have other specialties. You may have a cause that’s near and dear to your heart that is supported by one of these organizations.
