Global delegates agree to draft treaty to combat plastic pollution.

Global negotiators have agreed to produce a draft treaty to end plastic pollution, a preliminary but crucial step toward tackling one of the most lasting sources of human waste. Environmental advocates cautiously welcomed the outcome of five days of U.N. talks in Paris on plastic pollution, but expressed concern that the petroleum industry and some governments would water down the eventual treaty. Countries with big petroleum industries like the U.S., China and Saudi Arabia are focusing instead on plastic recycling, and want country-by-country rules instead of across-the-board limits.
