Answer:
The author wants to highlight the fact that food waste can be addressed in the same way as other waste.
Step-by-step explanation:
In this text, the author employs juxtaposition by presenting two contrasting ideas in order to encourage a comparison. The author first presents the idea of the recycling of paper, aluminum, glass, and plastic. He states that the community has done a great job with these objects. He then states that now is time to do the same with food waste. The purpose of such a contrast is to highlight the fact that food waste can be addressed in the same way as other waste.
