Several countries have implemented large-scale planting efforts: China, Ethiopia, India, Brazil, Australia, Pakistan, and Turkey to name a few. In 2019, Ethiopia claimed to have planted over 350 million trees in a single day as part of a broader initiative to plant 4 billion trees within a year to fight climate change.
