A bill has been filed in the Florida House to ban the oil and gas-drilling process known as “fracking”. Environmental groups and some lawmakers have long wanted to block fracking in Florida, but legislation has not passed. Fracking involves injecting water, sand and chemicals underground to create fractures in rock formations, allowing natural gas and oil to be released. While supporters say fracking increases production and holds down energy costs, opponents argue it threatens water supplies and can cause environmental damage.
