For example, if you want to get married, you would have to pay to plant 10 trees (25 if you later need a divorce). When purchasing a car, you would need to plant 20 trees, 40 if it's a light-duty van or 60 if it's a heavy vehicle. When trading estate, 10 trees would be required to sell a house, 20 to sell a business.
The idea is that all these activities harm the environment and so we should give something back. The law aims to recover the rainforest and offset the country's carbon emissions. Conservative estimates from the Brazilian Institute of Geography and Statistics calculate that about 65 million trees would be planted per year under the proposed rules.
