The tiger has its teeth and sharp claws. Humans have a great intelligence, but we don't always use it. The carelessness of humans has placed many animals on the endangered species list. Some animals have even become extinct. We will never see another one alive again.
Some animals compete with humans for space to live.
As humans take up more and more room, it becomes harder for some animals to find the food they need to survive. Other animals are unable to adapt to the changes humans make in their environment. The tiger is one of the animals affected. Tigers used to roam the rain forests and grasslands of Asia in great numbers. But today a tiger sighting is rare.
