Bill Nye

Watching groups of living things
Tryin' to find their reasoning
Get the scope, and watch some more

Populations I have seen
Are made of groups of living things
And if you're keepin' score

They compete for food
They compete for homes
Populations all compete
As everybody knows

Populations
There are different populations
Competeing to survive
Populations
And watching populations
We learn about life

The human race is growing fast
Other populations might not last
Some species are gone forever

Now we've got to watch what we do
Let other species live here too
We can all be here together

We compete for food
We compete for homes
Populations all compete
As everybody knows

Populations
There are different populations
Competeing to survive
Populations
And watching populations
We learn about life
