The theme for this year is: Help Heal the Planet
Most of us remember a time when windshields needed frequent cleaning from insects and yards were alive with birds and butterflies. Fields once held cocoons, chrysalises, and egg cases, and backyards teemed with insect and bird life. Today, these are far less common, raising the question: where have all the birds and bugs gone?

Since the 1970s, North America has lost more than three billion birds—nearly one-third of its population. Insects, the foundation of the food web, have declined by over 40%, with some regions experiencing losses of up to 75% of flying insects. A single chickadee requires nearly 9,000 caterpillars to raise one brood; when insects disappear, birds cannot survive. Habitat loss, pesticide use, and climate change are the primary drivers of these declines.

We can do our part to help heal the planet by making thoughtful choices at home. Planting native species that require less water and fertilizer, avoiding pesticides and herbicides, and creating backyard habitats for insects can make a meaningful difference. Gardens can become vital links in pollinator corridors, helping restore ecosystems one plant choice at a time.
