Campaigners in Wales say water contamination is the biggest risk facing the environment if fracking gets the go-ahead from the UK government.
Earthquakes are not the biggest risk of fracking, the huge risks are water contamination and climate change.
Last year, minor earthquakes at a fracking site in Lancashire caused the government to stop work continuing there. A report has today found that there was a link between the tremors and the work being done, but it has concluded that fracking could resume again under strict new guidelines.
Campaigners who are protesting against a site in the Vale of Glamorgan say while earthquakes are a concern, the main threat to the environment is a chemical leak into the ground.
They are calling on the Welsh Government to take a step back and make sure processes are in place to limit risks.
It only takes a little drop of a lethal toxin chemical from the transport of the chemicals to the fracking site to have a huge effect on humans and animals.
