Across
- 2. development that meets the needs of the present without compromising the ability of future generations to meet their own needs
- 7. a beach town
- 9. natural resources that can supply a natural income of goods or services;
- 10. an estimate of an ecosystem's production of natural resources but also of its absorption and cycling of materials in biogeochemical cycles like the carbon cycle. The biocapacity of the earth is about 1.7 global hectares of productive land per person.Carrying Capacity: the the number of people, other living organisms, or crops that a region can support without environmental degradation.
- 17. contaminants from numerous widely dispersed origins
- 22. A Dam
- 23. Assessments a report completed before development to assess the environmental, social and economic impacts of the project, predicting and evaluating possible impacts and suggesting mitigation strategies for the project.
- 24. the population, this is an indication of unsustainability.
- 25. More economically developed country (such as the USA)
- 26. the use and management of resources that allows full natural replacement of the resources exploited and full recovery of the ecosystems affected by their extraction and use.
- 27. is the day when humanity's demand for ecological resources and services is greater than the Earth's ability to regenerate those resources in a given year. The consequences of ecological overspending include:
Down
- 1. A worldview that shapes the way an individual or group of people perceives and evaluates environmental issues
- 3. contaminants from a single clearly identifiable site.
- 4. A technocentric viewpoint argues that technological developments can provide solutions to environmental problems. This is a consequence of a largely optimistic view of the role humans can play in improving the lot of humanity. Scientific research is encouraged in order to form policies and to understand how systems can be controlled, manipulated or changed to solve resource depletion. A pro-growth agenda is deemed necessary for society’s improvement.
- 5. (or contaminant) is the addition of a substance or an agent to an environment through human activity, at a rate greater than that at which it can be rendered harmless by the environment, and which has an appreciable effect on the organisms in the environment.
- 6. food production
- 8. can occur when lakes, estuaries and coastal waters receive inputs of nutrients (nitrates and phosphates), which results in an excess growth of plants and phytoplankton.Biochemical oxygen demand (BOD) is a measure of the amount of dissolved oxygen required to break down the organic material in a given volume of water through aerobic biological activity. BOD is used to indirectly measure the amount of organic matter within a sample.
- 11. An anthropocentric viewpoint argues that humans must sustainably manage the global system. This might be through the use of taxes, environmental regulation and legislation. Debate would be encouraged to reach a consensual, pragmatic approach to solving environmental problems.
- 12. 3 types of goods that can be taken from a forest ecosystem: timber, fiber, food
- 13. An ecocentric viewpoint integrates social, spiritual and environmental dimensions into a holistic ideal. It puts ecology and nature as central to humanity and emphasizes a less materialistic approach to life with greater self-sufficiency of societies.
- 14. the yield obtained from natural resources;
- 15. frequent extreme weather events
- 16. erosion
- 18. Less economically developed country (such as Haiti)
- 19. Justice Courtyard and Outdoor learning Lab
- 20. 3 ecosystem services provided by a forest ecosystem: oxygen production; flood protection; protection from soil erosion
- 21. loss Carbon dioxide buildup in the atmosphere
- 23. the area of land and water required to sustainably provide all resources at the rate at which they are being consumed by a given population. If the EF is greater than the area available
