What's the Rainforest Worth?
by Mark Buckley

Measuring the value of all the plants, animals, and benefits of the rainforest is impossible. We must show its monetary value to counter the timber and agriculture interests which want the land cleared. Immediate value can come by harvesting the fruits, vegetables, wild chocolate, rubber, and other quickly-replenished items. A study of one hectare of rainforest found that the final profit from logging was $1000, harvesting earned $422. In just over two years it's more profitable to not log.

Rainforests patiently hold many available foods we've never tried. Foods are available which could help to feed the starving nations. New Guinea, just north of here, has the winged bean, a vegetable which has parts that are similar to spinach, green beans, peas, potatoes, soybeans, flour, and coffee, not to mention that it grows incredibly fast and has built-in nitrogen fertilizer.

We know that just visiting a rainforest is valuable. The revenue from ecotourism is starting to show this. In Costa Rica, a historically agricultural nation, the revenues from ecotourism exceed those of banana and coffee.

Many of our medicines come from rainforest plants and animals. A pharmaceutical company paid $1 million to Costa Rica to test some of their rainforest plants, which is called bioprospecting or ethnobotany. One plant found, which treats cholesterol, brought in $735 million in one year. I'm sure there are many other valuable prizes waiting, but by clearing rainforest areas the size of a football field per second, we're probably destroying them before we ever know what exists in them. All of the wonderful products and beauty that the rainforest brings to us are just a few of the reasons to save this disappearing natural wonder.
