(CNN)Ethiopia planted more than 353 million trees in 12 hours on Monday, which officials believe is a world record.
The burst of tree planting was part of a wider reforestation campaign named "Green Legacy," spearheaded by the country's Prime Minister Abiy Ahmed. Millions of Ethiopians across the country were invited to take part in the challenge and within the first six hours, Ahmed tweeted that around 150 million trees had been planted.
"We're halfway to our goal," he said and encouraged Ethiopians to "build on the momentum in the remaining hours." After the 12-hour period ended, the Prime Minister took to Twitter again to announce that Ethiopia not only met its "collective #GreenLegacy goal," but exceeded it.
A total of 353,633,660 tree seedlings had been planted, the country's minster for innovation and technology, Getahun Mekuria, tweeted.
