Plants move around naturally – Isn’t thier arrival part of a natural cycle?
It is true that plants’ populations will expand or contract in their native ranges as local climates change. This movement usually occurs slowly, over periods of thousands of years. plants and animals will also have time to adapt and change. We are concerned about the invasions that humans have caused. When we bring non-native plants, quickly and in large numbers, from far away geographic areas the result is the decrease of our own native biodiversity which does not have time to adapt to these rapid changes.
