What are the threats to the three sisters?

The "Three Sisters" refers to the traditional agricultural practice of planting corn, beans, and squash together, which can face several threats. Key challenges include pests and diseases that can affect crop health, climate change leading to unpredictable weather patterns, and soil degradation from intensive farming practices. Additionally, competition from invasive species and changing agricultural policies can undermine the sustainability of this ancient farming method. These threats can impact not only crop yields but also the cultural heritage associated with the Three Sisters farming system.
