What happens if you change the North and South Poles?

If we swap the North and South Poles of the Earth, then our planet will gradually become empty and become absolutely lifeless. Liquid water will never again exist on the planet. All beautiful forests, deep rivers, vast seas and even oceans will turn into the most ordinary deserts, where there is nothing at all except a heap of dust. The temperature, pressure and composition of the atmosphere will change. In addition, the strongest radiation will spread. In short, the Earth will become a kind of Mars.
