The tiger is one of the most alert animals. And yet, today tigers are in danger. What do you think are some of the dangers to tigers in the jungle?
Answer: Even today, there are some dangers to tigers in the jungle. The biggest threat is from the hunters who kill them for their skin. Lions are also a threat to tigers since they are more powerful than tigers. They also face dangers from forest fires, destruction of trees, humans, etc.
Can human beings also be a threat to animals? How?
Answer: Yes, human beings are also a threat to animals. The increase in human population has led to the destruction of forests. This reduces the natural habitat for animals. Mainly humans kill animals for their skin, for example, deer are killed for their skin, elephants for their tusks, rhinos for their horns, tigers for their skin, etc.
