Which renewable energy source holds the most promise for the future? What are the environmental impacts of large-scale renewable energy projects (e.g., solar farms, wind turbines)?

6

Vaccination

Mandatory vaccination policies for public health.

Do mandatory vaccination policies infringe on personal liberties? What role does scientific consensus play in public health policies? How can vaccine hesitancy be addressed effectively?

7

Animal Testing

The ethical necessity of animal testing for medical advancements.

Are there sufficient alternatives to animal testing? Is it morally justifiable to use animals for human benefit? What regulations should govern animal research?

8

Nutrition & Health

The impact of ultra-processed foods on public health.

Should governments impose stricter regulations on food advertising? Is personalized nutrition the future of health? How do gut microbiome discoveries change our understanding of health?
