To reduce their negative impact on the environment people who brew coffee should buy beans that are grown naturally. Which piece of evidence is the best support for the claim?

The best piece of evidence to support the claim that people should buy naturally grown coffee beans to reduce their negative impact on the environment would be:

1. A study showing that naturally grown coffee beans require fewer or no chemical pesticides or synthetic fertilizers. This evidence would demonstrate that by choosing naturally grown beans, individuals can help minimize the release of harmful chemicals into the environment, reducing pollution and preserving ecosystem health.

2. Research indicating that naturally grown coffee farms employ sustainable farming practices, such as agroforestry or shade-grown methods. This evidence would highlight how purchasing naturally grown beans supports environmentally friendly agricultural practices, promoting biodiversity and habitat preservation.

3. Data revealing that coffee farms adhering to organic or natural growing practices have lower greenhouse gas emissions compared to conventional farms. This evidence would emphasize the role of naturally grown beans in mitigating climate change and reducing carbon footprints associated with coffee production.

In conclusion, the strongest piece of evidence that would support the claim is a study demonstrating that naturally grown coffee beans require fewer or no chemical pesticides or synthetic fertilizers.
