Habitat change occurs more frequently through natural causes than human activity.
a. true
b. false

False. Habitat change occurs through natural causes but human activity is a major contributor to this. In fact, our “growing” industries are one of the major causes of the destruction of many habitats in the planet. As a result, the ecological balance of life is destroyed, that is why we are experiencing major climate changes in our environment. 

That is true! many fish species traveled to the u.s. because of it.
