Worms Put New Life into Derelict Site: Reading Answers
Urban brownfields, abandoned lots and derelict industrial sites pose environmental, social, and economic challenges. An often-overlooked ally in their rehabilitation is a humble creature: the earthworm. This write-up explains how worms help restore degraded land, what "reading answers" means in this context, and practical steps for harnessing soil-fauna-driven regeneration.
Q: What were the main benefits of using worms in the experiment? A: The introduction of worms improved soil structure, enhanced nutrient cycling, boosted microbial activity, and increased biodiversity.
Based on the passage, the Hallside site remained unused for over a decade due to contamination. The reclamation plan was proposed by Scottish Greenbelt and HL Banks, employing a mix of specific worm types over a 5-10 year period. The project aimed to transform the soil structure and remediate heavy metal contamination. Summary Completion (Summary)
- Soil Enrichment: The worms efficiently converted organic waste into a rich, nutrient-dense compost that significantly improved soil quality.
- Vegetation Growth: As soil health improved, seeds and seedlings of native plants were introduced. The enhanced soil fertility supported rapid and robust vegetation growth.
- Biodiversity Increase: The site began to attract various insects, birds, and small mammals, indicating a rise in biodiversity.
- Carbon Sequestration: The project contributed to carbon sequestration efforts, as the worms and plants worked in tandem to absorb CO2 from the atmosphere.
Section B: True / False / Not Given
| Statement | Answer | |-----------|--------| | The derelict site was originally a landfill. | False (It was an industrial site, not a landfill.) | | The worms were added without any other materials. | False (They added manure and organic waste as bedding/food.) | | The worms reduced the total amount of heavy metals in the soil. | False (They did not remove metals; they changed their chemical form, making them less harmful.) | | Plants began to grow again within one year. | True (Grasses and pioneer species appeared in 12–18 months.) | | The method has been tested only in the United Kingdom. | Not Given (The passage mentions a UK pilot but does not rule out other countries.) |
The result: Within 18 months, the derelict site is transformed into a grassy, plant-covered area—essentially a new ecosystem.
