Big numbers are so common that we become numb to them. Fossil fuel subsidies are $5.3T per year. Break that down by month, week, day, hour, minute, and second and it is still just a number. It exceeds, however, the amount spent by all governments on health care; which, sadly ironically, is spent on curing people of the ills from pollution. Subsidies for renewable energy are used as arguments against its adoption, but they are only $120B per year, 1/45th the amount spent on fossil fuels, hardly any health care costs involved.
