As Spiritalk says, earth is changing. Over the past million years, the continents changed a lot. There will be NO APOCALYPSE, so do not worry, it is a natural process for the tectonic plates to move, thus changing the relief. Take a look at this image:

But yes, people are damaging our planet and over time there will be an end to Earth, but untill then if I'm right, we'll already become space explorers and will have colonised other planets. Humanity should change it's behaviour about industrialisation and resources.
