Today TreeSisters is planting 2. Some algae fuel is already being sold and experts predict that by the technology will be refined to the point where the price per gallon will break even with the cost of petroleum. To mitigate the crisis, one measure they are likely to promote is reducing deforestation and planting trees.
Scientists have been experimenting with using them to remove heavy metals from contaminated industrial sites, as the ferns actually absorb them from the soil and store them in their tissues. The institute was founded by Jonas Salk, the developer of the first safe polio vaccine, who wanted to create a world-class centre for biological research.
Worse, trees emit reactive volatile gases that contribute to air pollution and are hazardous to human health. The constant tillage required to plant and replant grains slowly degrades soil over time and leads to erosion by water and wind.
Western nations, including the United States, Britain and Norway, handed over millions of dollars to developing countries to kick-start programs to reduce tropical deforestation. Implementation to date has sometimes failed to include stakeholders.
