What is an important issue for our times, but is currently under-discussed?

1. Climate change. Many people deny climate change under the belief that "our temperature has been changing over time". What they don't realize is that it's true, but you need to look deeper into it. What causes climate to change is Carbon Dioxide (CO2), and we humans, are producing tons of CO2 emissions per day, which is what triggers climate change.

2. Police Brutality. Black people should be treated the same as white people, even if they surrender to police.

3. Euthanasia. Should people have the right to kill themselves in a legal way? Well, it's their lives.

4. Abortion. Should a mother abort her baby under special circumstances?
