gather, process information and use available evidence, to discuss the changing methods of dealing with plant and animal diseases, including the shift in emphasis from treatment and control to management or prevention of disease
Background
There has been a shift from waiting for a disease to occur, to preventing the occurrence of the disease. This can be seen in agriculture where genetically resistant crops are grown so that the plants do not have to be sprayed for diseases later in life. Animal and plant diseases have been managed by quarantine restrictions in Australia. Diseases, such as foot and mouth, rabies and plum pox, are managed by not allowing infected organisms to enter the country. World-wide immunisation has caused diseases such as small pox to be eradicated.
- Consider all the aspects of the disease you have studied. Make notes on those aspects that relate to the above syllabus statement.
- Using these notes, plan a discussion of the changing methods of dealing with plant and animal diseases.
- Decide whether you need further information, and if so, gather it from textbooks or the Internet.
- Write a short concise response from the available evidence to show what you deduce about the shift in emphasis from treatment and control to management or prevention of disease. Make sure the response has:
- an introductory paragraph, written in general terms
- a series of paragraphs that focus on specific issues. Each paragraph could discuss any debatable issues, e.g. advantages and disadvantages of a particular approach
- a concluding statement, providing your position or recommendations based on your evaluation.
