Explanation:

Individual action refers to the actions taken by one individual person, acting based on his or her personal decisions. Collective action refers to the actions taken by a collection or group of people, acting based on a collective decision. For example, if you choose to walk instead of drive, then you are taking an individual action. Or, if you are part of a neighborhood that chooses to install sidewalks to help people there walk more, then you are involved in a collective action. Collective action often involves larger scales, since there are more people involved. However, it is possible to take individual action on large-scale issues, such as reducing greenhouse gas emissions to reduce global climate change.
