Create a vibrant illustration featuring a stylized planet with a smiling face at its center. Replace the globe with a tree that has colorful leaves and a whimsical design. Instead of butterflies, include whimsical birds perched on its branches. Add a variety of flowers and plants around the base of the tree, incorporating a mix of geometric shapes and bright colors. Surround the scene with a soft, pastel background to enhance the cheerful, eco-friendly theme.
