Passage:
In the southern canals of Mexico City, the ancient agricultural system of *chinampas*—artificial islands created by the Aztecs—is experiencing a modern renaissance. Once the primary source of food for the pre-Hispanic valley, these 'floating gardens' have faced decades of degradation due to urban sprawl, water pollution, and the introduction of invasive species. However, a collaborative initiative involving local farmers, biologists, and urban planning institutions is working to revitalize this ecological heritage. By integrating traditional farming techniques with modern water filtration systems, project organizers have successfully restored soil quality and re-established native crop production in select canals. Beyond preserving cultural heritage, the project aims to establish a self-sustaining local food supply, reducing the city's reliance on long-distance agricultural imports. Critics argue that the scale of the restoration is too small to make a significant impact on Mexico City's vast food demands. Nonetheless, proponents emphasize that the *chinampas* serve as an invaluable, scalable model for climate-resilient urban agriculture, demonstrating that ancestral knowledge can offer practical solutions to contemporary resource crises.
Based on the passage, which statement best expresses the main idea of the text?
- AThe restoration project has successfully improved soil quality and re-established native crops in the canals.
- BThe initiative will completely eliminate Mexico City's dependency on long-distance agricultural imports.
- Revitalizing the chinampas provides a scalable, climate-resilient model for urban agriculture by combining traditional and modern methods.Cevap
- DThe small scale of the chinampa restoration makes it incapable of addressing Mexico City's food demands.
