What are the advantages and disadvantages of Antarctic tourism to the Antarctic region? And what are the "some requirements" that all passengers must strictly abide by?

With each additional tourist, the impact of human beings on the Antarctic natural environment will increase by one point, so in order to protect this pure land, all tourists must comply with some requirements.

Wild animals in Antarctica are not afraid of people, and penguins will even go where they can reach, but in Antarctica, we must strictly abide by the rules of not chasing, touching or feeding wild animals.

Don't take stones from the South Pole. Many people have the habit of collecting stones as souvenirs from tourist destinations, but in Antarctica, please don't do this. Most of the Antarctic continent is covered with ice and snow, and there are not many stones exposed on the ground, especially those gravels, which are necessary materials for penguins and other Antarctic birds to nest. Although there are not many tourists in Antarctica, it will have a bad influence on the ecological environment if everyone shares a piece of the action.
