The atmosphere on the second dimension planet may have a different composition or lower oxygen levels, making it difficult for the children to breathe properly. Their bodies may not be adapted to the conditions of that planet, resulting in respiratory distress.

because we breathe in the oxygen which is flowing around this earth and when we breathe in this oxygen around us ,we also breathe in air pollution which is not good for all things living on this planet.
because plants breathe in carbondioxide and breathe out oxygen which animals and human breathe in if there is no carbondioxide there will be no plants ,no animalsand no humans which means no life on earth.
No, the only planet you can breathe on is Earth ^-^
