The most effective way to tackle climate change? Plant a trillion trees
Pakistan completed a billion tree plantation project in 2017 [1]. This is currently being followed up with a 5 year 10 billion tree plantation project, at an annual cost of 7.5 billion PKR (~47 million USD) [2]. Planting 989bn trees for the other 200 countries should not be too difficult.[1] https://en.wikipedia.org/wiki/Billion_Tree_Tsunami[2] http://www.radio.gov.pk/04-07-2019/pms-vision-of-clean-green...
