When U.S. grain giant Cargill opened a $20 million port in...[Santarem]...it expected to cash in on the rising global demand for soybeans...Instead, the...company today is under fire from residents, environmentalists and federal prosecutors, who say the port is illegal and are suing to shut it down...Soy farming [is]...the worst destroyer of the rainforest..."All I can say is that Cargill did everything the state told us we needed to do to open up the port," said...the port's administrative manager. Prosecutors say Cargill failed to comply with...regulations by not conducting an environmental impact assessment for the port and by building it on top of sensitive a pre-Colombian archaeological site. Cargill did not respond to repeated requests by [AP] for comment on the charges. In February, Brazil's second highest court gave Cargill six months to carry out the environmental survey. The company...[is] appealing while the port's fate awaits the study's results...[prosecutor said] the port's very existence has sped deforestation in the area...The company also has tried to clean up its environmental image. Giovannini said for the next harvest the company could require soy farmers who sell to Cargill to present certificates that their soybeans were grown in accordance with...environmental laws...most of [Santarem's] 330,000 residents live in poverty.
