Well, the introduction of a new species into an environment can cause big problems. [A cow giving birth]
Without any natural predators or other factors to keep its reproduction in check, it can
soon wreak havoc. [Lots of deers appear]
For example, rabbits brought to Australia by European settlers soon bred like, well…rabbits,
leading to the extinction of many native plants.
So let’s not cross A off our list just yet…
What about B - People altering the environment?
What happens if you chop down a forest? [A forest with lots of trees chopped down]
Other than, you know…the trees screaming…
Everything that lived there becomes homeless. [Animals in a deserted forest]
And that certainly qualifies as being disruptive.
So B could be right, too…
Then there’s C… natural disasters.
Not much you can do about these, right? [A palm tree blowing in the wind]
And when they do, any ecosystem in its path is in for some big changes.
So C is looking good as well…
The correct answer is D:
All of the above.
Invasive species, human impact, and natural disasters can all cause a disruption in the
balance of an ecosystem. [Explosions appear all over the Earth]
We are definitely not a fan of disruptions in balance.
What an awful time to have to try and catch a Frisbee… [Dog catching a frisbee]
