Aresearcher and students wants to study the effectiveness of a new cancer drug. to do this, they plan on injecting rats with cancerous cells and then administering the drug to half and administering a placebo to the other half. their data will be stored electronically, and collaboration between the researcher and students will be done over e-mail. what are some of the ethical concerns regarding this study, and how can they remedy these issues?

One of the major ethical concerns would be the well being of the rats used for experimentation. Upon receiving the cancerous cells, the rats could die. If the new drug ends up not working, it could cause the animals to suffer side effects before dying. This issue could be solved by conducting the research on tissue samples in the lab, rather than on animals.

the invasive species was introduced due to commercial purpouses, as there was a demand for fur clothes and hence, a business opportunity connected to this product. actually, it was when the nutrias scaped, causing harm to the us ecosystems when they acquired the status of invasive species. in this case they have caused an environmental problem, but it could have affected also economic interests or even human health.
