Ozone is considered a bad thing when it is in the troposphere, where it acts as a greenhouse gas and contributes to air pollution. In this layer of the atmosphere, ozone can be harmful to human health and the environment, as it can cause respiratory problems and exacerbate conditions such as asthma. It is created at ground level primarily by the reaction of sunlight with pollutants like volatile organic compounds (VOCs) and nitrogen oxides (NOx).

In contrast, ozone in the stratosphere is beneficial as it forms the ozone layer, which protects the Earth from harmful ultraviolet (UV) radiation from the sun.

Therefore, the correct assessment is: **When it is in the troposphere acting as a greenhouse gas trapping heat in the planet and breathed in by humans.**
