The Amazon Rainforest is the world's greatest natural resource—the most powerful and bio-actively diverse natural phenomenon on the planet. Yet still it is being destroyed just like other rainforests around the world. The problem and the solution to rainforest destruction are both economic. Rainforests are being destroyed worldwide for the profits they yield—mostly harvesting unsustainable resources like timber, for cattle and agriculture, and for cropping by rainforest inhabitants. However, if land owners, governments and those living in the rainforest today were given a practical economic reason NOT to destroy the rainforest, it could and would be saved. Thankfully, this practical economic alternative does exist. Many organizations have demonstrated that if the medicinal plants, fruits, nuts and other resources like rubber and chicle (树胶) were harvested sustainably, rainforest land has much more economic value than if timber were harvested or if it were burned down for cattle or farming operations. Sustainable harvesting of these types of resources provides this value today as well as more long-term income and profits year after year for generations to come.
