Hi Shafaat, thanks for submitting your science content entry. Looks like your idea is to plant more trees as part of a tax and prevent deforestation. The best part of your idea is how you showed the calculations to demonstrate that your idea is affordable. Also, this is another part that really stood out in your idea and we will directly quote it here from your content: 'Generally some capitalist persons of a country earn thousands times more than others and they own maximum number of factories and mills which are disaster for nature. As a result, those who are doing more damage to nature will plant more trees.' Very nicely written. Thank you and here is the full link to your contests entry: https://drive.google.com/file/d/1imFr9H9K7ms2MXrXH_o-Trg_YbBlo0H_/view
