Worms Put New Life Into Derelict Site Reading Answers

Worms dig deep vertical tunnels. This breaks up compacted, industrial soil.

In the final paragraph, David Craven is quoted as saying the cost of land bioremediation “could have been more than £30 million.” The question uses slightly different wording (“estimated the cost... at over £30 million”), but the meaning is identical. This tests your ability to recognise paraphrasing.

Global ecological projects have demonstrated that integrating earthworms into land reclamation schemes drastically shortens recovery timelines. For instance, on old coal mining spoil tips, researchers have found that introducing specialized earthworm populations alongside pioneering plant species (such as clover or hardy grasses) can form a functional, fertile topsoil layer within just a few years—a process that would naturally take centuries.

The Hallside project has inspired similar regeneration plans for other contaminated steelworks sites. This demonstrates how nature-based solutions can address industrial pollution while creating economic opportunities through tree harvesting and renewable energy development. worms put new life into derelict site reading answers

Explanation: Paragraph 6 states that researchers found earthworms were "able to speed up the process of soil recomposition".
