There are a lot of wonderful nonprofit organizations doing great work every day fighting for environmental causes. This includes work to improve our climate, better environmental policies, education, directly cleaning our air through tree planting, preserving natural resources, and protecting wildlife.
Unfortunately, for-profit organizations and governments often do not have the incentive to care about our prosperity-giving environment. Nonprofit organizations play a crucial balancing role against this.
These great organizations need your support. They have the benefit of being laser-focused on creating a better world but are limited by the resources to bring that to life. If you have little to spare, do some research to find causes that mean something to you and donate.
