Unnatural causes are when people are made to become ill or die because of things that are not naturally happening. Inequality making us sick means that people are sick or dying because they don't have the same access to things like food, healthcare, and safe places to live, that people with more money have. Inequality means that some people have more money and resources than other people. So if people with more money and resources are able to buy better foods, live in safer places, and have access to better healthcare, people with less money will not have those same advantages. This can mean that the people with less money can become more ill or even die, even if they have the same medical condition as someone with more money. Inequality can also lead to worse working conditions, and more exposure to things like pollution, that can make people sick. In short, unequal access to resources means that some people are more likely to become sick or die than others.
