| Question | Answer |
|---|---|
| 4.2 discuss three ways human activity has adapted, or may be required to adapt, to climate change: desalination | desalination facilities that remove salt from water pos - provides clean drinking water to over 300 million people - replenishable neg - mass CO2 released to power facility -increased water bill price -release of salt and impurities to oceans |
| 4.2 discuss three ways human activity has adapted, or may be required to adapt, to climate change: prescribed burns | prescribed burns pos -reduced fuel load (reducing severity of fires) -germination and regrowth of native species neg -increase of smoke, reduces visibility and increases risk of illness (i.e. asthma) -reliant on private landowners compliance |
| 4.2 discuss three ways human activity has adapted, or may be required to adapt, to climate change: genetically modified species | genetically modified species species that have genetically modified to cope with the changing environment pos -good financial return for farmers -less pesticides required neg -health risks (allergic reactions) - DNA cross contamination |
| 4.3 Discuss how two strategies aim to mitigate global climate change: renewable energy | renewable energy pos -electricity without greenhouse gasses -often cheaper than fossil fuels neg -not able to eliminate all CO2 production (other areas that produce CO2) -life span of equipment can be short (often exposed to natural elements) |
| 4.3 Discuss how two strategies aim to mitigate global climate change: dietary changes | dietary changes shift to plant based diets or lab grown meat pos -reduction in land and water use for agriculture -reduction in CO2 produced from agriculture neg -hard to convince people to change their diet -negative views on lab grown meats |
| 4.6 explain two strategies designed to address the impact of land cover change: local environment | Dirk Hartog island national park: Return to 1616 why -deforestation, soil erosion and degradation, biodiversity loss and invasive species how -weed management and vegetation recovery -killing invasive species and reintroducing native species |
| 4.6 explain two strategies designed to address the impact of land cover change: regional environment | Gondwana Link why -due to mining, agriculture, deforestation and urban expansion -invasive species, loss of ecosystem services and soil erosion how - 1000km of habitat revegetated, restored and reconnected |
| 4.6 evaluate two strategies designed to address the impact of land cover change, using the concept of sustainability: local, social | Dirk Hartog island national park: Return to 1616: social pos - education programs, and websites -prison traineeships, new jobs - works with Aboriginal people on strategies neg -labour of killing invasive species -pollution caused by tourism |
| 4.6 evaluate two strategies designed to address the impact of land cover change, using the concept of sustainability: local, economic | Dirk Hartog island national park: Return to 1616: economic pos -funding from multipe government sources - provides job opportunities neg -estimated to cost $16.7million and requires on going maintenance -if funding drops project suffer |
| 4.6 evaluate two strategies designed to address the impact of land cover change, using the concept of sustainability: local, environmental | Dirk Hartog island national park: Return to 1616: environmental pos -removal and eradication of invasive species, and reintroduction of native species -largest ecological restoration in southern hemisphere neg - pollution from tourism |
| 4.6 evaluate two strategies designed to address the impact of land cover change, using the concept of sustainability: regional, social | Gondwana Link: social pos -tourism industry, website -in 2020 4.4million hectares announced under indigens protection neg -relies on volunteers |
| 4.6 evaluate two strategies designed to address the impact of land cover change, using the concept of sustainability: regional, economic | Gondwana Link: economic pos -flexible due to income being from tourism -one government grant of $84,000 neg - heavily relies on private landowners and volunteers |
| 4.6 evaluate two strategies designed to address the impact of land cover change, using the concept of sustainability: regional, environmental | Gondwana Link: environmental pos -protection for native species to move safely -eradication of invasive species neg - poison used for invasive species can harm pets |
