>> hello, my name is sarah greenwald, a san francisco resident representing 350 san francisco. we're delighted to see the city government making a start on this action against the climate emergency. and we appreciate that supervisors brown and mandelman, who initiated the legislation, stated that these are only first steps. and as mr. hooper explains, that's absolutely correct. natural gas is methane, a powerful greenhouse gas, as you know. it's toxic. it's flammable. and it can explode. and it makes up about a third of san francisco's greenhouse gas footprint. so we look forward to working with you on further action, to ban natural gas in all new construction. and to retrofit existing buildings without evicting or displacing anybody, to get methane out of san francisco. so in closing, let me just say that, you know, on the titanic you would not like put a nail through a board and jump in the water and then think about building a lifeboat. and we're not on the titanic in the sense that there will be no other ship to rescue us. thank you. >> thank you. >> clerk: is there any fur
