Lawmakers in the United Kingdom are debating a new tax on disposable cups in an effort to cut down on waste.

While the so-called "latte levy" is controversial, the goal is to replicate the success of Britain's tax on plastic bags; their use has declined by 80 percent since the tax was introduced in 2015. Proponents of the tax say it would encourage people to carry around their own reusable cups rather than use disposable ones, which in their current form are difficult to recycle.

Over 26 hours and across 39 time zones, the world is celebrating the end of 2017.

New Year's celebrations kicked off in Samoa, Christmas Island and New Zealand as those countries were the first where the clock struck midnight.

Author Peter Zheutlin never wanted a dog, let alone a rescue. He had always believed, as a lot of people do, that rescue dogs are damaged goods.

Now Zheutlin can't imagine life without a dog, and he's become so driven by the issue of stray dogs that he's written two books about it. He tells Here & Now's Lisa Mullins the number of stray dogs has "cascaded out of control" in some parts of the U.S.

The Palestinians threatened on Saturday to cease communication with the United States if the White House closes its diplomatic mission in Washington, D.C., lodging a potential thorn in President Trump's plans for Mideast peace.

The State Department says the office of the Palestine Liberation Organization must close under a little-known provision in U.S. law that forbids it from requesting Israelis be prosecuted for crimes against Palestinians. Trump may reverse the closure within 90 days if the Palestinians prove they are engaging in peace negotiations with the Israelis.

More than two weeks after Hurricane Maria made landfall on Puerto Rico, the island's power grid remains in shambles, and authorities say it will take months to fully restore electricity.
