One of the major problems that has occured with human movement is the transportation of invasive species.  As people move around (or now, as they import things) species that are native to one area are moved to another.

The reason this is a problem is because the biome to which the species is being brought is often not "ready" for that new species.  The species in the "target" biome are not adapted to the new species.  So, for example, there are often no organisms that will eat the new species.  This means that the new species will grow rapidly when it arrives in the new biome.  It can often choke out many of the native flora of the biome.

One of the major problems that can develop is that one plant may have a virus that spreads to new plants.  However, the worst problem that I have seen has occurred in the South and in lakes. 

In the south many years ago someone brought in a plant called Kudzu.  The plant loved the climate and began to take over and cover other plant species.  As a result of the plants overgrowth many preexisting plants have died off and the ground cover and even trees are covered by Kudzu.

Another problem has happened with boats.  When a boat goes into the water it picks up certain plants on propellers.  In Minnesota, the boats went from lake to lake adding a new species of seaweed that over took many of the plants in the lakes.  They crowded them out which killed the plants that belonged in the lake.  This caused other species that fed off of the plants to die off as well which has changed many of the lake habitats.
