GGH3701 ASSIGNMENT 2 REVISION EXAM WITH CORRECT ANSWERS AND VERIFED QUESTIONS GRADED A+ Read the following statement and indicate whether it is TRUE or FALSE: Improvements in fishing methods result in greater numbers and varieties (sizes and species) of fish being caught, but fishing in the Southern African region remains sustainable and no overfishing is taking place. - ANS-False You are an environmental specialist, and must choose the most suitable intervention or solution for the following scenario: A known and already protected endemic plant species has been discovered by the local community in an area bordering the Table Mountain National Park. Cape Nature has requested that appropriate actions be taken to preserve this endemic plant species, which has not been degraded in the area bordering the National Park. Evaluate the given scenario and select the most appropriate intervention and action which will have the most significant and immediate effect to ensure that this endemic plant species is preserved? 1. Management; legislation needs to be amended to include the protection of the endemic species. 2. Response; ordering the permanent closure of the demarcated area and removal of the community. 3. Reconstruction; the relevant endemic species should be removed from the area and planted s - ANS4. Conservation; demarcate the given area and recommend that the borders of the Table Mountain National Park be extended to include the area in order to preserve the endemic plant species You are an environmental specialist, and you must choose the most suitable intervention or solution for the following scenario: A community located close to the abandoned mine dumps of what was once a functioning gold mine in Johannesburg, complains about increased cases of asthma, bronchitis, eye irritation and various other health issues, especially during dust storms. The municipality needs an intervention and solution to decrease these dust storms and assist the community as soon as possible to avoid further significant health issues. Evaluate the given scenario and select the most appropriate intervention and action which will have the most significant and immediate effect to decrease the dust storms from these abandoned mine dumps and assist the affected community with their reported health concerns. 1. Responses; rehabilitate the mine dumps by planting suitable plants to minimise soil erosion and wind erosio - ANS-1. Responses; rehabilitate the mine dumps by planting suitable plants to minimise soil erosion and wind erosion, and consequently decrease the severity of dust storms You are an environmental specialist, and you must choose the most suitable intervention or solution for the following scenario: Read the following: Members of a growing settlement near St. Lucia in South Africa have observed that the estuary has dried up; in fact, the estuary has been permanently cut off from the sea. Sightings of some endemic estuarine organisms have also decreased, and it seems that the whole estuary has been lost. Evaluate and select the primary cause for this observation. 1. Shipping and transportation of goods 2. Periodic extended droughts 3. Increased freshwater needs owing to coastal developments 4. Increased freshwater pollution from various settlements - ANS-3. Increased freshwater needs owing to coastal developments Durban Bay located in the eThekwini municipality has become physically vulnerable especially after April 2022 primarily due to --- and ---. 1. increased flooding; accelerated erosion 2. increased agriculture; economic growth 3. mineral exploration; shipping 4. pollution; decreased rainfall - ANS-Increased flooding; accelerated erosion Read the following: An urban settlement with surrounding agricultural areas is located upstream of an estuary. The urban settlement has been growing quite rapidly and there is pressure on agricultural activities to sustain the growing human population. An estuary located downstream is consequently negatively affected - the estuary mouth has closed permanently. Evaluate and select which ONE of the following puts the biggest pressure on the estuary? 1. Rapid rate of soil erosion 2. Loss of fish species 3. Oil pollution from shipping 4. Human health issues - ANS-1. Rapid rate of soil erosion Read the following: Recent reports focused on the assessment of water quality of some of South Africa's major beaches. The reports have shown a general downward trend in the standard of water quality especially in regions which have experienced rapid population growth. Evaluate the given scenario and determine which one of the following is the primary cause for this observation. 1. Increased shipping and transportation of goods 2. Increased freshwater needs owing to coastal developments
