Food waste is an enormous issue. Some have too much, others, not enough or at all. And, of course, there's an environmental issue. But there's a solution, and it's much easier than you think:

One man in Saudi Arabia's city of Hail has put a fridge outside his home and called his neighbors to fill it with the food they can't eat in a day.

The anonymous man said he wanted to spare the poor from asking for help since many are ashamed.

This noble act became viral after leading Saudi Muslim cleric Sheikh Mohamad al-Arefe tweeted:

"I've always said the people of Hail are generous. A man puts a fridge outside his house for leftover food; an indirect act of charity for the needy. Oh, how I love you, Hail!"

Sheikh al-Arefe has 8.6 million followers on Twitter. This tweet already had over 5000 retweets, and it's easy to see why. The random acts of kindness are beautiful reminders that restore our faith in humankind.

Social media users greeted this act and asked for people who have plenty to make more significant portions and share fresh meals with the ones in need.

Many stated that this is a "great act of charity." We only hope that this whole idea doesn't end in one city, in one block. We can't feed the world, but we can help those who are near us, yet most of the time, they are sadly invisible.

It's a win-win situation. Good for the humankind and great for the environment!
