Answer:
"Concern" is a word that can be used as a noun or a verb, and it generally refers to a feeling of worry or interest in something.
Step-by-step explanation:
As a noun, "concern" can refer to an issue or problem that someone is worried about. For example, "Environmental concerns are a major issue in today's world."
As a verb, "to concern" means to cause worry or to be relevant to a situation. For example, "The recent increase in crime rates concerns many people in the neighborhood."
In our lives, concern is important because it drives us to take action to address problems and improve our situation. Concern about our health, for example, may lead us to exercise regularly and eat healthily. Concern about the world around us can motivate us to get involved in efforts to make a positive impact, such as volunteering for a cause we care about or supporting political candidates who share our values.
By paying attention to our concerns and taking action to address them, we can improve our own lives and the world around us.
