The best statement that expresses a central idea of the text is:
A. Earth Day had an important impact, but people don't like what it has become.
Here's why:
- The text explains how the original Earth Day started as a powerful political event in 1970 that led to significant environmental laws and raised awareness nationwide.
- It also discusses how over time, particularly since the 1990s, Earth Day has changed, with a shift toward corporate involvement and a focus on individual actions, which some environmentalists criticize.
- The article highlights mixed feelings among environmentalists today—while supporting the activities like trash cleanups, many feel the original political urgency and effectiveness of Earth Day have diminished.
- Other answer options do not fit because:
- B. The text shows grassroots involvement was crucial, not just Congress leaders.
- C. The Youth Climate Strike is presented as a new, energizing force, not unnecessary.
- D. The text points out Earth Day controversially balances corporate and individual roles, but does not say it prioritizes corporate responsibility over individual action.
Therefore, choice A best captures the main theme: Earth Day was once a groundbreaking event but now faces criticism about how it has evolved.
