Proforestation
The great forests that have long existed on the Earth draw in huge amounts of carbon from the atmosphere. Proforestation is protecting the forests there still are, encouraging them to continue to heal and grow.
Ocean Transport
Ocean transport poses several sustainability challenges due to its carbon emissions, air pollution, ballast water, oil spills, marine pollution, noise pollution, waste disposal, overfishing, inefficient shipping routes, labor issues, and light disturbances.
