hain saws roar, a tree grows in the Amazon plains rumble slowly in the fall. This is to be harvested each year in Brazil, one of thousands of trees. The difference is, the tree was felled a tree close to a micro-chip. Forest protection agencies hope that this little chip will help crack down on illegal felling of forest behavior.

■ Experiment

Currently, a "green action" organizations are 巴西马托格 Grosso state "Calanda" farm in the early experiments. Farm area of about 100 hectares, of which two thirds of forest land, and one-third planted with corn, soybeans and vegetables and other crops.

Forestry experts to the size of a microchip into a white plastic ID card, and then placed in the root of the tree. Chip to store the trees location, size, cutting agencies and other information.

After the trees were cut down, this chip will be entered as the timber through the rough market, so buyers can clearly understand the source of wood.

"Green Action" organizations that, although the limited scope of the current experiment, but the micro-chip to protect the future of forests contribute significantly to the Amazon plains.

"Now, people often talk about from the 'forest sustainable development action' of the timber, the system (chip) can be used as proof," Reuters quoted 11 "Green Action" forest expert Paul Borges as saying.

"Green Action" group said the benefits to the wood with a lot of chips. The first is to protect the forests from deforestation. At the same time, these chips can also help Forestry main written document from the tedious to prepare, while reducing the environmental regulatory pressure on the department.

In addition, the "Green Action" organization that "The Untouchables" in the chip allows those fake documents trying to hack through the trees, there is no opportunity criminals, but also help reduce the associated corruption.

Currently, Bolivia and Nigeria are also using bar codes or satellite tracking system against illegal logging, protection of fragile ecosystems.

■ Support

"Green Action" group said selective deforestation, without prejudice to the forest not only under the premise of economic benefits and may even increase the forest "capture" carbon dioxide. Lumberjack chips also support the plan.

"I think this is a good idea," 52-year-old woodcutter Aristides Ferrari said, "We do not want all the forests are cut down. Instead, we want to ensure that forests remain, so that we can continue to work. "

Non-profit organization "Committee of the forest," the officials responsible for science things, Gary Dodge said affixed to the wood chips also have some disadvantages, such as timber production will increase costs. However, this seems not so much. Reuters said that in some markets, can prove the exact origin of the timber sales prices will be higher
