HELP Reflect and Respond
Can you think of two more ways that humans have either positively or negatively impacted a given
species and its survival? What have we done that has increased that species' survival? Decreased?
How could we do better in the future to preserve the diversity of life on Earth?
A sample answer might include: There are many things humans have done to decrease the
likelihood that species will survive. A few, such as rats or domestic dogs, likely have increased. Yet
we have moved many invasive species around the globe, assisting their dispersal while devastating
native populations. Environmental conditions and resource use or preservation are other factors that
might be touched on.
