SC.7.E.6.6 Identify the impact that humans have had on Earth,
such as deforestation, urbanization, desertification, erosion,
air and water quality, and changing the flow of water.
How have human activities impact Earth’s air,
water, and land resources and what are the
consequences?
Plastic on the Trail Page Keeley
One summer day, five friends went hiking on a local trail. One of the friends
saw some plastic litter on the trail. He picked it up and said, "I will pick this up,
because I don't like to see litter, and I don't want this plastic to end up in the
ocean."
This is what his friends said:
 Bob: I agree that we should not litter, but my personal actions here in this town
don't impact the ocean.
 Chris: This plastic is pollution because it is man-made material in a natural area,
but we don't need to worry about it because it doesn't seem to be affecting any
animals right now.
 Nancy: The trash and pollutants people put into the environment everywhere
can affect the ocean, life in the ocean and on land.
 John: I also agree that we should not litter, but the ocean is so incredibly huge
that pollution is not a problem. Garbage just disappears in the ocean. Which
friend do you most agree with and why? Explain your thinking

An epoch is the beginning of a
distinctive period in the history
of anything. Earth's geologic
epochs—time periods defined
by evidence in rock layers—
typically last more than three
million years.
According to the International
Union of Geological Sciences
we are officially in the
Holocene (“entirely recent”)
epoch, which began 11,700
years ago after the last major
ice age.
That label is outdated, some experts say. They argue for
“Anthropocene”—from anthropo, for “man,” and cene, for
“new”—because human- kind has caused mass extinctions
of plant and animal species, polluted the oceans and
altered the atmosphere, among other lasting impacts.
Some scientists are suggesting Earth has already entered a
new age—several million years earlier than it should have.
Has the Earth entered a new epoch?
