Washington, Oct 2 (ANI): Earthworms, which have burrowed their way through the ground for 300 million years, have become the latest secret weapon in the war against climate change.
Instead of just wriggling around and providing food for birds, earthworms can help prevent flooding and droughts, a major four-year study has revealed.
Floods and droughts are caused by cycles of dry weather and monsoon-type rains, said by some experts to be caused by global warming.
And this is where the humble earthworm can help the planet.
The average worm weighs less than half an ounce but it is able to eat through a third of its own weight in soil a day.
When worms tunnel the soil absorbs more water - meaning that in their millions worms can turn the ground into one vast sponge soaking up the water in floods but retaining it during dry spells.
Now farmers can play a vital part in combating the devastation caused by floods and droughts by encouraging earthworms, according to experts.
When fields are not ploughed, the soil condition is improved naturally by the tunnelling of earthworms
"Our research shows that farmers can make a huge difference in helping to mitigate the effects of climate change," the Daily Express quoted Dr Chris Stoate, head of research at the society's Allerton Project farm, as saying.
"When fields are not ploughed, the soil condition is improved -naturally by the tunnelling of -earthworms, which absorb water at a rate of four to 10 times that of fields which are without worm tunnels.
"This in turn helps the soil to take up water during storms and to retain it during drought. It also helped to buffer our stream from flooding during heavy rain," he added. (ANI)
