learn that Easter Island is now essentially deserted, but at one time as many as 10,000 people lived there. He also learned that the environment is radically different now than it was when the first people arrived. It was once covered by a lush rainforest but now supports only minimal, low vegetation.

What claim might Jamal make about the impacts of the over use of trees on the inhabitants of Easter Island?

• The people of Easter Island began to rely more on an agricultural society versus hunting and gathering.

• Since trees were considered wealth, landowners became even more wealthy and powerful.

• The people of Easter Island were no longer able to find resources to make clothes and canoes.

Which component of this proposed model provides the one most likely explanation for how cutting down trees might impact the amount of rainfall?

• Tree roots hold the soil together to prevent erosion

• Trees increase humidity through transpiration

• Only the roots of the trees are affected by water

• The soil supplies nutrients to the tree

Use your understanding of environmental impacts due to human involvement to design a solution that could have allowed the Easter Island civilization to maintain itself by preventing deforestation. Discuss • how the solution’s impact would be monitored

• how the solution would be effective in addressing the main cause of the problem

The Earth's climate has changed throughout history. In the last 650,000 years there have been seven cycles of glacial advance and retreat, most of which are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. Which of these human impacts most likely caused the greatest change in atmospheric CO₂ levels, leading to increased global warming and climate change?

• increased dependence on nuclear power

• agricultural practices implemented by farmers to meet increasing demand for food resources

• rapid population growth

• over consumption of resources
