Luckily, there's an app for that.
Swedish startup Karma buys leftover food from restaurants, cafes and grocery stores and sells it to hungry customers looking for a half-price meal.
"Being able to make a profit from solving a problem while creating value for both restaurants and consumers makes this a fantastic opportunity to build a business where you don't have to choose between cause or profits," Karma CEO Hjalmar Ståhlberg Nordegren told Forbes in a profile published Tuesday.
Ståhlberg Nordegren founded Karma in Sweden in 2016 with three friends— Elsa Bernadotte, Mattis Larsson and Ludvig Berling.
Initially, Forbes contributor Alison Coleman reported, the restaurants were hesitant to admit that they wasted food, or to believe that there could still be profit in the food they did discard.
But the founders spent time talking to store and restaurant owners to understand how to pitch the idea from their perspective, and many have since come around. Karma estimates that participating restaurants can make an extra €50,000 a year.
The app works with more than 1,500 businesses to provide discounted food to more than 350,000 users, among them three of Sweden's largest grocery stores.
It is available in more than 150 Swedish cities and also expanded to London in February, where it now works with more than 400 restaurants.
Bernadotte told The Evening Standard in February that moving to London was an important test case of the app's international appeal.
"The food waste problem here is huge as well—much bigger because it's a bigger country," she told The Evening Standard. "We also think London is a great fit because it has one of the best food scenes in the world, a high number of restaurants and retailers who care about sustainability, as well as a population that is both environmentally conscious and digitally native."
London restaurants Aubaine, Michelin-starred Aquavit, vegetarian restaurant Tibits, Yamabahce, Magpie, Essence Cuisine, Calcutta Street, Hummus Bros, Detox Kitchen and Arkett were early participants.
For diners in other countries eager to save money and the planet, there is good news.
Karma announced August 15 that it had raised $12 million in investments that it intended to use to grow its staff, expand within supermarkets and spread internationally, beginning in Europe.
The company currently has a staff of 35 in Stockholm and aims to have a staff of more than 100 in five markets by the end of 2019 and a staff of more than 150 by 2020.
The move comes after regional authorities declared a state of emergency over the weekend after sightings of more than 50 bears in the town of Belushya Guba since December.
This year's letter from Bill and Melinda Gates focused on nine things that surprised them. For the Microsoft-cofounder, one thing he was surprised to learn was the massive amount of new buildings the planet should expect in the coming decades due to urban population growth.
"The number of buildings in the world is going to double by 2060. It's like we're going to build a new New York City every month for the next 40 years," he said.

After a dearth of action on climate change and a record year of extreme events in 2017, the inclusion of climate change policies within the annual legislation Congress considers to outline its defense spending priorities (the National Defense Authorization Act) for fiscal year 2018 was welcome progress. House and Senate leaders pushed to include language that mandated that the Department of Defense (DoD) incorporate climate change in their facility planning (see more on what this section of the bill does here and here) as well as issue a report on the impacts of climate change on military installations. Unfortunately, what DoD produced fell far short of what was mandated.
Trump is losing his rallying cry to save coal. The Tennessee Valley Authority (TVA) voted on Thursday to retire two coal-fired power plants in the next few years despite a plea from the president to keep one of the plants open.
Earlier this week, the president posted an oddly specific tweet that urged the government-owned utility to save the 49-year-old Paradise 3 plant in Kentucky. It so happens that the facility burns coal supplied by Murray Energy Corporation, whose CEO is Robert Murray, is a major Trump donor.
