1. Replace: "Alternatives to the unnecessary use of animals for teaching and research purposes."
by: "Experiments on animals only if there is a clear need and no alternative methods are possible."
Reason: The draft is ambiguous: is it saying that some use of animals in teaching and research is unnecessary, or that all such use of animals is unnecessary. If the latter, I would disagree. For example, I think new drugs should be tested on animals before they are tested on humans.
2. add the words "Research on" before "alternatives to shark nets and the culling of sharks."
Reason: There are currently no proven alternative methods of deterring sharks. Any such methods would need to be tested, not only for their effectiveness in deterring sharks, but also for any adverse effects on other marine life.
