The two sources disagree on the effectiveness of recycling programs in schools.
Source 1 emphasizes that the participation of many people (such as those in school districts) is necessary for recycling to have a positive environmental impact, suggesting that large-scale participation is beneficial.
Source 2, however, highlights the challenges of getting all students to follow a specific recycling program, indicating that this can make the program ineffective.
Therefore, the correct point of disagreement is:
"There are too many people in a school district to follow one plan."
This statement reflects the concerns raised in Source 2, contrasting with the idea in Source 1 that participation is key to successful recycling efforts.
I'm confident in this analysis.
