Ecosystems are delicate arrangements where plants and animals all depend on each other for survival. The disappearance or introduction of any animal species disrupts the balance and negatively impacts upon other plants and animals by breaking the food chain and altering the habitat in which they live. Such imbalances frequently return to haunt us in unexpected ways.
