France's latest efforts to reduce pollution will also affect nature lovers hitting the countryside for an outdoor meal: Under a controversial new ban, picnickers won't be able to buy plastic goblets to drink their beloved wine, or plastic knives to make ham and butter baguette sandwiches.

Life in the office will be different, too, as coffee machines will no longer cough out plastic cups, as part of the country's plans to be more environmentally friendly.

The measure, which took effect last month, gives producers until 2020 to ensure that all disposable dishes sold in France are made of biologically sourced materials and can be composted. It follows a ban on plastic bags, in place since July.
