LONDON — For Lent, many Christians give up indulgences like tobacco, alcohol or sweets, or transgressions like lying and swearing. And for Anglicans, don’t forget synthetic fabrics, wet wipes, and those little boxes that hold dental floss.

The Church of England has asked people to add a new culprit to the list of ills they forsake for the six weeks of penance that begin on Ash Wednesday: plastics. Specifically, the church wants people to avoid the plastic consumer products and packaging that have become a major environmental problem, polluting oceans and rivers, fouling beaches, killing wildlife and clogging landfills.

“I think it might well be a first for us, to have an entire Lent program on an environmental issue, but it is very much an integral part of what the church is about,” said Ruth Knight, the Church of England’s environmental policy officer. In fact, environmental stewardship “to safeguard the integrity of creation” is one of the five “marks of mission” the church lists in describing its purpose.

The church’s “Lent Plastic Challenge” arrives on a wave of anti-plastic sentiment and legislation in Britain and across Europe, as more people conclude that the first element of the motto “reduce, reuse, recycle” should take precedence. In December, the European Union announced binding waste-reduction targets for member nations, with particular emphasis on plastics.
