Methyl bromide, used to disinfect soil before planting strawberries, which is 60 times damaging the ozone layer then chloroflurocarbons, which are banned in America. Methyl bromide is acutely toxic, exposure to high concentrations can cause damage to the respiratory and central nervous systems even cause death. The United States is responsible for about 40 percent of the 72,000 tons of methyl bromide used worldwide every year, with California alone producing 80 percent of the nation’s berries and 20 percent of the global market — 1.5 billion pounds yearly. Farmers credit methyl bromide along with the mild, coastal climate (their fields are four times more productive than any other state) for their $750 million crop.
