Invertebrates make up 97 percent of all the species of animals, led by the ubiquitous insects and especially beetles. As such, they are integral to the ecology of all ecosystems. They help to make up the great variety in life that brings joy and beauty to humans, and allow the stunning balance of systems, whereby plants, animals, and microorganisms relate in harmony—so much harmony that the Gaia theory holds that the earth acts like one giant organism. The corals, earthworms, butterflies, oysters, squids, crabs, sea anemones, spiders create a world that reflects the creativity of the Supreme Being, who provided humanity with an environment of rich diversity in color, form, sounds, and behavior. It is the human responsibility to help maintain the balance and diversity, and thus the human desire to protect and nurture the environment. Nonetheless, human impacts on the environment, such as pollution, habitat destruction, introduction of foreign species and so forth, has often manifested as having negative impacts on invertebrates. It is important for humans to consider future generations in their relationship with the environment, looking seven generations in the future with respect to their impacts, as some Native American leaders have stated.
