To plant multiple trees usually depends on a large amount of people, the use of technology, or a combination of both. These routes will be looked at here, first looking at India.
In India last year, 1.5 million volunteers planted 66 million trees in 12 hours, which is most likely a new record. Saplings of 20 different species were place along the Narmada river in Madhya Pradesh. This is an example which shows what can be done with political will and a recognition of what is needed in this time of anthropogenic climate change. India is third in the world for carbon emissions.
Another route being explored for mass planting is the use of drones. The startup Biocarbon Engineering uses drone technology to fire seed pods into the ground, with follow-up care done by local communities. A hectare of planting can be covered in 15 minutes, with preferred projects of 100 hectares. One hundred thousand pods can be planted in a day. This technological route bodes well for the future, although care is still needed to make a seed grow into a tree.A third route, is to combine humans and technology to achieve large scale planting. This is what we are working on at Teratrees, which also has the advantage of connecting young people to Nature. We believe through many humans and the internet, many projects can be initiated, and we continue to work towards this goal.
