I recently decided to go for a walk on a seasonably warm afternoon. I got out of my car at a wooded recreation area and immediately noticed how much cooler the air felt, thanks to the biggest plants on Earth – trees. From my years growing up on and then managing my family’s organic walnut farm I have a deep respect for trees. They provide countless benefits to us and the planet. They provide food and shelter, they cool and improve air quality, so it’s important to me to protect this valuable resource from invasive pests and diseases.
