The playful renderings on the Cartoon Butterflies Visa Gift Card will delight children and give you a chance tell the kids something about these creatures beyond their aesthetic value. The presence of butterflies and moths indicates the functioning of a healthy ecosystem. They help pollinate plants and provide natural pest control. Unfortunately for the butterflies, the latter comes at considerable sacrifice, as they are prey for birds, bats and other creatures. They are model organisms for scientists who study habitat loss and climate change. Celebrate nature with Cartoon Butterflies Visa Gift Cards.
