Enhancing Argument on Climate Action

In her essay on environmental conservation, Sara argues that individual actions contribute significantly to combating climate change. She shares several personal anecdotes about reducing waste and supporting local sustainability initiatives. However, she realizes that her examples do not comprehensively illustrate the impact that collective action can have on a larger scale. In the following passage, select the most effective addition to enhance the argument's development and provide a broader context for her points.

"While I have made personal choices to reduce my carbon footprint, such as recycling and using public transport, the real change comes when communities come together to create policies that promote renewable energy sources. For example, in cities where community-driven programs have been implemented, there has been a noticeable decrease in greenhouse gas emissions. Additionally, these efforts can inspire surrounding areas to follow suit, leading to a snowball effect of sustainable practices and policies. This collective action ultimately demonstrates a profound understanding of the problem and the necessary solutions to address it."
