On the BP Oil spill in the Gulf, a bit of perspective, perhaps:
As the studies extended into a second year, scientists noticed how fast the marine environment recovered, helped by naturally occurring microbes that feasted on the oil and degraded it.
Perhaps due to those microbes, aquatic life along the shoreline in Texas had returned to normal within three years — even as tar balls and tar mats remained along the beaches, sometimes covered by sand, according to Wes Tunnell, a marine biologist at Harte Research Institute of Gulf of Mexico Studies at Texas A&M University in Corpus Christi.
“We were really surprised,” Lizarraga said. “After two years, the conditions were really almost normal.”
