After years of heavy application of glyphosate (Roundup) herbicide, farmers are struggling with superweeds that have developed resistance.

GOP pundits and politicos -- as well as some Democrats -- are spewing
a mess of sayings that some call "irresponsible" in response to the Gulf oil
spill. Hate-talker Rush Limbaugh accused 'environmentalist wackos' of having
blown up the rig, and former White House spokesperson Dana Perino echoed him.
Neither presented any evidence for the insinuations.

"Scientists say the Gulf oil spill could get into the what's called the Loop Current within a day, eventually carrying oil south along the Florida coast and into the Florida Keys." After that, it could continue into the Gulf Stream.

"Engineers and welders successfully rejoined two huge water pipes inside a muddy crater early this morning, and state officials said they hope to restore clean water within days to 2 million residents of Greater Boston."

"The Cumberland River having reached its crest was little comfort amid fears that receding floodwaters could reveal more victims of deadly storms that swamped much of middle Tennessee."

Dispersants used on the Gulf oil spill may have toxic effects and harm ecosystems -- raising questions about whether the cure is worse than the disease. Companies refuse to disclose some of the ingredients, saying they are trade secrets.

"National Oceanic & Atmospheric Administration officials last fall warned the Department of Interior, which regulates offshore oil drilling, that it was dramatically underestimating the frequency of offshore oil spills and was dangerously understating the risk and impacts a major spill would have on coastal residents."

Although BP has said it will compensate victims, "lawmakers and Gulf Coast residents began questioning whether the company will take full responsibility for the economic losses stemming from the spill. ... A law passed after the 1989 Exxon Valdez spill requires companies to pay for cleanup costs but no more than $75 million for other damage."

"U.S. officials closed commercial and recreational fishing in a large swathe of waters hit by the growing oil spill in the Gulf of Mexico, the National Oceanic and Atmospheric Administration said on Sunday."
