Across
- 4. The scientific study of the protection and management of biodiversity.
- 6. A layer of ozone high in the Earth's atmosphere that absorbs and blocks most of the sun's harmful ultraviolet radiation.
- 8. Energy derived from sources that are naturally replenished, such as sunlight, wind, and hydropower.
- 9. Waste that poses a threat to human health or the environment due to its toxic or harmful nature.
- 12. Natural resources that can be replenished over time, such as sunlight, wind, and water.
- 15. The responsible management and sustainable use of natural resources to preserve biodiversity and ecosystems.
- 18. The measure of human impact on the environment, representing the amount of land and resources needed to support a population's lifestyle.
- 19. Water sources that are naturally replenished, such as rivers, lakes, and groundwater, and can be used sustainably.
- 21. A close and long-term biological interaction between two different species, often providing mutual benefits.
- 22. Energy derived from sources that are naturally replenished, such as solar, wind, and geothermal energy.
- 23. Farming practices that aim to provide food while preserving the health of the soil, water, and air.
- 25. An underground layer of permeable rock or soil that holds and transmits groundwater.
- 28. The variety of living organisms in a particular habitat, including the genetic diversity, species diversity, and ecosystem diversity.
- 29. A community of living organisms and their interactions with the physical environment.
- 30. Harvesting fish from the ocean at a rate that exceeds the species' ability to replenish, leading to population declines.
Down
- 1. The total amount of greenhouse gases, particularly carbon dioxide, produced directly or indirectly by human activities.
- 2. Organic materials that can be broken down by natural processes, reducing environmental impact.
- 3. Non-native species that, when introduced to a new ecosystem, can cause harm to the environment, economy, or human health.
- 5. Capable of being broken down by natural processes into simpler, harmless substances.
- 7. Gases, such as carbon dioxide and methane, that trap heat in the Earth's atmosphere, contributing to the greenhouse effect.
- 10. The cleanliness and purity of the air, determined by the presence of pollutants.
- 11. The clearing of forests, often for agricultural purposes, leading to the loss of biodiversity and disruption of ecosystems.
- 13. Resources that are finite and cannot be replaced on a human timescale, such as fossil fuels.
- 14. The natural process of decomposing organic material into nutrient-rich soil.
- 16. The introduction of contaminants into the environment, causing adverse changes.
- 17. An area of land where all the water drains into a common water body, such as a river or lake.
- 20. Practices or processes that can be maintained over the long term without negatively impacting the environment.
- 24. The process of collecting and processing materials to be used again, reducing the need for new raw materials.
- 26. The specific environment where an organism or community of organisms lives.
- 27. Rainfall with increased acidity due to the presence of pollutants like sulfur dioxide and nitrogen oxides.
