One of the main reasons for the increase is visibility: today’s teenagers are growing up with parents I disagree with your statement because they don’t get influenced from their parents.

this sentence is not correct help me

Increase in what visibility? What is visible? The colon is incorrect. The conjunction "because" is better. You have two sentences here, run together: "...with parents. I disagree..."

I apologize if my previous statement was not clear. Allow me to rephrase it for better clarity.

One of the main reasons for the increase in visibility is that today's teenagers are growing up with greater access to information and exposure through various media platforms. This increased visibility allows them to be exposed to various perspectives and influences, which may not necessarily align with those of their parents. Hence, a teenager's beliefs and opinions may differ from their parents due to the diverse sources of information they encounter.
