Explain three ways on how air pollution harms people in areas where it is prevalent

1. diseases - when people are constantly being exposed to air pollution, it may cause them various lung diseases such as asthma and other respiratory problems
2. global warming - when air is polluted, it also affects the global warming as our planet is constantly getting warmer
3. plants are dying - with no enough fresh air to breathe, humans cannot release enough carbon dioxide which plants need to create oxygen

Hamlet's fourth soliloquy is probably his most famous one - "to be or not to be."it is rather different from his previous soliloquies because now he is contemplating something that didn't come up before - suicide. he is thinking whether it is worth it to fight to find his father's murderer when in the end all of them are going to die, so why not die sooner than later. he is contemplating if he should go on fighting or just kill himself and end it all, which is why this soliloquy in particular is rather depressing, hesitant, and gives a deeper insight into hamlet's madness.
