Engaging in the Fight Against Extinction Unit Driving Question: How can we, as planetary stewards, take an active role in saving species from extinction?
The Sixth Mass Extinction? Lesson Driving Question: How have humans impacted Earth for better and for worse?
1. Engage students to consider how humans have made a lasting mark on the planet.
- Use Google Earth to show students satellite images of a place that has visible signs of human impact (such as Disney World; New York City; Las Vegas; Tagebau Hambach, Elsdorf, Germany; the Democratic Republic of the Congo).
- Ask students to discuss the following:
- What is the human impact on these locations?
- Which of these impacts are permanent?
- Which could be changed over time?
- Build students’ background knowledge using multimedia resources. Share with students that they will need to be able to define Anthropocene Epoch using these sources:
- Distribute a copy of the Exploring the Anthropocene Epoch handout to each student. Guide students through a close reading of the first three sections (listed below) of The Age of Humans: Evolutionary Perspectives on the Anthropocene article and have students respond to the first five questions on the handout.
- Section 1: What is the Anthropocene?
- Section 2: When did it begin?
- Section 3: Why does the Anthropocene matter?
- After students have completed reading and answering questions one through five on the handout, conduct a full-class discussion to review students' responses.
3. Students brainstorm and classify what they believe to be the positive and negative qualities of humans on the Exploring the Anthropocene Epoch handout.
- Have students answer question six on the Exploring the Anthropocene Epoch handout. Give students a few minutes to brainstorm both positive and negative human qualities that they believe influence humanity’s impact on the environment and list these qualities in the appropriate columns of the T-chart.
- In their research teams, have students share their brainstormed lists and work together to identify the most positive and negative qualities that specifically influence environmental issues.
- Positive examples: creativity, cooperation, problem solving, kindness, adaptability, common sense
- Negative examples: laziness, vanity, selfishness, vengeance, discrimination, hypocrisy
- Call on students to share one of their examples of a positive or negative trait and provide an example of how that positively or negatively impacts Earth.
- Explain that as students begin work on their projects, they will find evidence of these traits both in actions that lead to extinction and in efforts that support species survival. Then, when developing their pamphlets, they can appeal to these traits when proposing specific action steps that others can take to prevent the extinction of a species.
4. Debrief students by having them respond to closing questions.
- Facilitate a class discussion about how the positive and negative qualities of humans can either help or hurt the future of our planet. Ask:
- As planetary stewards, which human qualities will be most important to protecting the future of the planet?
- What actions can we take to emphasize our positive qualities and support the sustainability of Earth?
- What actions might you personally change to make yourself an even stronger planetary steward?
- Have students write their responses to the following questions on two sticky notes:
- What do you want Earth to look like in the future? To what parts of our planet do we need to pay more attention?
- What changes do you think humans will need to make in order to have that future?
- Label two pieces of chart paper with the questions and direct students to place their sticky notes with their answers on the appropriate paper. These questions will be revisited later in the unit.

The Anthropocene Epoch, or the Age of Man, is the name given to the time period up to the present in which humankind has had a significant impact on the natural world. Though the date of the start of this new era is debated, the Anthropocene follows the Holocene, which started about 12,000 years ago, when humans began engaging in agriculture, in addition to hunting and gathering. Due to the impacts humans have had on Earth’s biomes, evidence suggests that we may be causing the extinction of many of Earth's species, and perhaps, even our own.
Recommended Prior Activities
period of time during which human activities have impacted the environment enough to constitute a distinct geological change.
all the different kinds of living organisms within a given area.
area of the planet which can be classified according to the plant and animal life in it.
organism threatened with extinction.
particular period of time in history marked by an event that begins a new period.
having to do with the present geological time period. The Holocene Epoch began at the end of the last glacial period, about 10,000 years ago.
extinction event in which a large number of species go extinct in a relatively short period of time.
group of similar organisms that can reproduce with each other.
responsible management to ensure benefits are passed on to future generations.
