If deadly dinosaurs still existed what would be about the best thing about it?
the best thing about being alive when dinosaurs stalked the earth is they will eat my enemies and if there trained dinosaurs they can eat predators.
But the worst thing about being alive with dinosaurs is the dinosaurs might eat you and they might eat the trees and stomp on buildings.
If kiwi birds went extinct there will be heaps of bugs because birds eat grubs on the forest floor and without kiwi birds New Zealand won't have any native birds.
But the best thing about life in new Zealand alongside kiwi birds is new Zealand will have a native bird and they will eat bugs so that bugs don't make massive colony's.
