Sulphur Dioxide - a gas produced by burning certain fossil fuels & waste plastics - is soluble in water, which then falls as "acid rain". It is classed as an "indirect greenhouse gas" In Europe, this was found to be killing forests in Norway, Sweden and elsewhere. The main source was determined to be coal-fired power stations, also domestic heating and industry. The cure was to retro-fit equipment to "scrub" the flue gases in power stations - making gypsum in the process - and to use low-sulphur fuels. . . Not my Image : Fair Use & public information
