Which greenhouse gas is primarily associated with human activities? A) Water vapor. B) Ozone. C) Nitrogen dioxide. D) Methane.

Understand the Problem

The question is asking to identify which greenhouse gas is mainly linked to human activities from the given options. This involves understanding the role of each gas in relation to human impact on climate change.

More Information

Methane is one of the key greenhouse gases associated with human activities such as agriculture, particularly from livestock and rice paddies, as well as fossil fuel extraction.

Tips

A common mistake is to confuse water vapor as heavily human-influenced, yet it's largely natural and not directly controllable by human actions compared to methane and carbon dioxide.
