How do you explain the fact that today many European languages are spoken all over the world?

Colonialism.

Explanation:

The empires of Europe i.e. Great Britain, Spain, Portugal, France and to a lesser extent Belguim, Italy, Netherlands & Germany conquered the majority of the world and suppressed native cultures and languages by forcing European ideals and languages on them.

within these regions are all the major types of biomes in the world. a biome is a community of animals and plants spreading over an extensive area with a relatively uniform climate. some diverse biomes represented in north america include desert, grassland, tundra, and coral reefs.
