because...... if they are gone, so are sparrows and so are hawks and so on. Just like sunlight, or plants, we need them too
Most ecosystems ultimately rely on sunlight as the source of energy. Sunlight is used by plants to manufacture food. Plants are eaten by herbivores, and herbivores are in turn eaten by top-level consumers like hawks. Therefore hawks ultimately depend on sunlight for their food. At the bottom of the sea, near thermal vents, scientists have discovered new ecosystems that do not rely on sunlight, but on the chemicals and heat present at those vents as a source of energy for bacteria, which are eaten by larger organisms. The top level consumers in those ecosystems do not depend on sunlight for their food.
