Scientists are trying several strategies to help save forests, Gillis reports. They've suggested that counties with more wealth should pay people in tropical areas to stop destruction of forests for agriculture and logging. Another plan is to thin out forests in the American West to prevent the spread of parasites and fires. Both ideas are stalling due to lack of funding. Tropical forest researcher Oliver Phillips told Gillis, “I think we have a situation where both the ‘forces of growth’ and the ‘forces of death’ are strengthening, and have been for some time. The latter are more eye-catching, but the former have in fact been more important so far.” To see an interactive map showing forest decline around the world, click here.
Even though many are predicting gloom and doom, Gillis reports that scientists also say the "point of no return" has not yet been reached and that many forests, like those in the Eastern U.S., are still sucking carbon dioxide from the atmosphere. Since CO2 is a major source of food for trees, some forests have seen an increase in growth, and a new study published in Science magazine says worldwide forests store a billion tons of carbon per year in wood. Scientists also acknowledge their predictions are crude; some predict the death of the Amazon forest, while others think forests will continue to be massive carbon-dioxide eaters through this century.
