| What is biodiversity? | The total variety of life in the biosphere. What are the three types of biodiversity? |
| 900s. What is climate change? | Long‑term changes in temperature and weather patterns. What is global warming? |
| Ecosystem diversity, species diversity, genetic diversity. What is ecosystem diversity? Variety of habitats, communities, and ecological processes. What is species diversity? The number of different species in an ecosystem. What is genetic diversit | |
| What is species diversity? The number of different species in an ecosystem. | |
| What is genetic diversity? Variety of genes within a species. | |
| What are benefits of biodiversity? Stability, productivity, resilience, food, medicine, raw materials, ecosystem services. | |
| What is resilience? An ecosystem’s ability to recover after a disturbance. | |
| What are ecosystem services? Benefits humans receive from ecosystems. | |
| Name seven ecosystem services. Provisioning, regulating, supporting, cultural, pollination, water purification, waste decomposition. | |
| What is an ecological footprint? The area of land and water needed to support a person or population. | |
| What is an anthrome? A human‑altered biome. | |
| What is the Great Acceleration? Rapid increase in human population, technology, and resource use since the mid‑1900s. | |
| What is climate change? Long‑term changes in temperature and weather patterns. | |
| What is global warming? Increase in Earth’s average surface temperature. | |
| What is deforestation? Clearing forests for human use. | |
| Effects of deforestation? Biodiversity loss, CO₂ increase, soil erosion, disrupted water cycles. | |

| What is habitat restoration? Returning ecosystems to a more natural state. | |
| How can scientific research help the environment? Identifying problems, developing cleaner technologies, guiding conservation. | |
| Name three environmental success stories. Bald eagle recovery, ozone layer recovery, reduced air pollution (Clean Air Act). | |
| What is sustainable development? Using resources without harming future generations. | |
| Sustainable development should provide for __________ while preserving __________. human needs; ecosystem services/natural resources. | |
