Pangaea probably was the first ever continent of Earth. Millions of years back all the Earth's landmasses were connected to each other and it was one huge landmass with oceans all around it. Thats why people in the past were able to migrate long distances. There weren't any oceans to obstruct their way.
Studies suggest that the Earth's landmasses will again come together to form a super continent. In a way this could be a good thing. People will be more connected to each other. But there is another problem. Will humans even exist when this super continent is formed? With our pollution habits we might only be able to see this wonder of nature if we are lucky.
With tectonic plates crashing against each other it will cause major physiological changes to the Earth's landmass. There will be many more mountains that will rise from the overlapping of continents. Volcanic activity will also increase. Not to forget the amount of seismic activity when all landmasses come together.
Weather changes will be very extreme. The coasts will experience pleasurable weather and temperature whereas the centre of this landmass would be like the Sahara desert only bigger. With landmasses coming together a lot of the land would become inhabitable which could become a very big problem.
Pangaea two would be an amazing creation of nature but it can only cause more problems for living organisms. Though it would be amazing for the generation to see this landmass from Space.
