Analysis-Tough US stance casts gloom over plastics pollution deal after Geneva flop

GENEVA (Reuters) -The collapse on Friday of a sixth round of U.N. talks aimed at curbing plastic output has dimmed hopes of tackling a key source of pollution and left many advocates of restrictions pessimistic about a global deal during the Trump administration. A three-year global push to reach a legally-binding treaty to curb plastic pollution choking the oceans and harming human health now appears adrift, participants said. Many states and campaigners blamed the failure on oil-producers including the United States, which they said hardened long-held positions and urged others to reject caps on new plastic production that would have curbed output of polymers.
