Final answer:
This television advertisement promotes climate change action through the peripheral route to persuasion by using emotional appeals rather than detailed logical arguments.
Step-by-step explanation:
The advertisement described relies on the peripheral route to persuasion. Instead of using data and logical arguments as in the central route, it uses stirring imagery and appeals to emotions by asking whether the natural beauty featured in the photographs is worth saving for future generations. Such appeals to emotion and aesthetics are characteristic of the peripheral route, as they do not require detailed processing of information but rather aim to generate positive associations and emotional responses.
