Think of the situation from the animal’s point of view. People are coming in from all over the place that the penguins don’t recognise. Here is a list of why tourism is bad.
The cruises and planes produce toxic fumes and co2 admissions
The tourists could get too close to the penguins resulting in the penguins getting nervous
We could upset their food chains and way of living
There is also some suggestions that the passengers might harass the wildlife
The animals are not use to humans
The ships may crash and pollute the sea and the water will become unclean
Many people want to take samples from Antarctica
Just think to yourself would you rather not go to Antarctica and feel that you have preserved and saved something or would you rather be self-centered and go there just for yourself satisfaction.
I say that Antartica should be left alone and we should leave the nature and animals to flourish and bloom.
