This year marks the 40th anniversary of Earth Day, so how can you incorporate travel and the environment on this day and beyond? We’ve got some ideas for you.

The first place to start your research is the official Earth Day Network: www.earthday.org.

Its Web site has a database of activities and events worldwide, including river and trail cleanups, tree planting and festivals.

So whether you’re planning to travel across the globe or to the local park, you can track down eco-minded organizations and communities.

The Sierra Club (www.sierraclub.org) has more than 40 public events through the month of April, including river cleanups and removing invasive species.

But even beyond that month, the Sierra Club hosts a series of outdoor adventures and volunteer vacations that are focused around helping the environment.

The nonprofit American Hiking Society (www.americanhiking.org) also sponsors at least 60 volunteer vacations a year involving clean-up and trail-building projects.

These range from short-term, family-friendly trips to more intensive experiences for advanced hikers.

The bottom line is the idea behind Earth Day is to raise awareness for environmental issues.

So while it’s great to commit to an earth-friendly activity on that day, it’s also possible to participate all year long.
