Example Input: Scientists on Monday described evidence of this bitter chapter of South American history preserved deep in an ice cap in the Peruvian Andes in the form of residue from the relentless clouds of metallic dust spewed from the mines starting in the 16th century. The mountaintop mines of Potosí in Bolivia were the world’s richest silver source. While the Incas had long extracted silver, a new processing method introduced by the Spanish in 1572 greatly increased production even as it belched lead dust and other pollutants into the atmosphere. The pollution blew over the entire region, including the Quelccaya Ice Cap some 500 miles (800 km) northwest in southern Peru. The Spanish refining process involved pulverizing silver ore, containing both lead and silver, into powder, which sent metallic dust into the atmosphere. The powder was mixed with mercury. The silver was separated by heating the mixture to allow the mercury to evaporate. Writing in the Proceedings of the National Academy of Sciences, the scientists said they drilled into the glacier at an altitude of about 18,000 feet (5,600 meters) to learn about past air pollution. The age of the ice was determined with precision because it was laid down in discernible layers caused by the annual alternation between wet and dusty dry seasons. The pollutants spawned by the Spanish colonial-era silver operations from the 16th century through the 18th century consisted mostly of lead but also arsenic and others. The researchers called it the earliest evidence of large-scale, human-produced air pollution in South America, beginning more than two centuries before the industrial revolution. The pollutants were reminders of “the sad conditions and fate of tens of thousands locals exploited in the silver mining operations during the colonial period,” Ohio State University environmental scientist Paolo Gabrielli said. “Their work conditions must have been truly terrible. Many died because of the strenuous physical efforts but it was also not infrequent that underground mine galleries collapsed, burying and killing hundreds of people,” Gabrielli said. Ohio State earth sciences professor Lonnie Thompson called the Quelccaya ice a “Rosetta Stone” for studying climate history, saying the samples also can reveal past temperatures, aridity and perhaps even the evolution of bacteria and viruses.
Example Output: Peruvian ice cap harbors evidence of conquistadors' avarice.

Example Input: "The annual effort to raise public awareness about the environment and inspire actions to clean it up marks its 41st anniversary on Friday, coinciding with the Christian Good Friday and Judaism’s celebration of Passover. In an effort dubbed ""A Billion Acts of Green,"" organizers are encouraging people to observe Earth Day 2011 by pledging online at act.earthday.org/ to do something small but sustainable in their own lives to improve the planet's health -- from switching to compact fluorescent light bulbs to reducing the use of pesticides and other toxic chemicals. “Millions of people doing small, individual acts can add up to real change,” said Chad Chitwood, a spokesman for the umbrella group coordinating efforts. There will be hundreds of rallies, workshops and other events around the United States, where Earth Day was born, and hundreds more overseas, where it is now celebrated in 192 countries. In the United States the activities range from the premiere of the new film from the director of “Who Killed the Electric Car?” (it’s called “Revenge of the Electric Car”) at the Tribeca Film Festival in New York to a discussion about creating a green economy in 12 cities along the Gulf Coast, where this time last year residents were reeling from the effects of the BP oil spill in the Gulf of Mexico. In the years since the first Earth Day was celebrated in 1970 the environmentalist movement made great strides with passage of the Clean Air Act, Clean Water Act, the Endangered Species Act and other groundbreaking laws. But the bipartisanship that marked the birth of Earth Day — it was sponsored in Congress by a Wisconsin Democrat named Gaylord Nelson and a California Republican named Pete McCloskey — is often missing in discussions about environmental policy today. Efforts to fight climate change by regulating greenhouse gases, for instance, face fierce resistance from many Republicans and members of the business community, who dispute the science supporting global warming and warn new rules to regulate emissions will kill jobs and raise energy costs."
Example Output: "Earth Day organizers call for ""a billion acts of green""."

Example Input: "Even ardent gun rights supporters are willing to talk gun control in the wake of the deadly shooting at Sandy Hook Elementary in Newtown, Conn.  During a Dec. 18 grilling by MSNBC anchor Thomas Roberts, U.S. Rep. Jack Kingston said gun control should be ""up for discussion"" alongside violent video games and mental health. The Savannah Republican was endorsed by the National Rifle Association in 2012 and received an A+ grade from the group. Changing gun laws may not be the answer, though. ""Connecticut has the fifth toughest gun control laws in the country, including an assault weapons ban that bans 35 different weapons,"" Kingston said. A Kingston spokesman did not reply to our request for more information, so we searched for state-by-state comparisons of gun control laws and reviewed Connecticut’s assault weapons statute. The term ""assault weapon"" is controversial. Various state laws use the phrase, although the National Rifle Association argues that gun control advocates created it to ""trick the public into believing that ‘assault weapons’ were fully-automatic machine guns used by the military,"" its website says. There’s no formal definition for what counts as an assault weapon. Laws describing them vary. In general, the term refers to a semi-automatic firearm that resembles a fully automatic one or those used by militaries. Connecticut law generally bans the sale, transfer or possession of assault weapons. State statute defines them in two ways: Connecticut’s law lists 37 guns, not 35, so Kingston’s not far from the mark. Technically speaking, the statute is written so that firearms outside the list can be prohibited, but this is a minor problem. What about Connecticut’s ranking? The Brady Campaign to Prevent Gun Violence uses a point system to rank states based on whether their statutes met the group’s standards on curbing firearm trafficking; background checks; child safety requirements and other factors. Connecticut’s laws were ranked the fifth strongest in the nation in 2011, the group’s most recent list. It was bested by California, New Jersey, Massachusetts and New York. Georgia tied for 22nd. The nutmeg state scored well consistently. We checked the rankings back to 2007 and found it made the top five each time. Still, Connecticut’s 58 points lagged well behind first place California, which earned 81 points. The state’s assault weapons ban was one reason why. It earned only three out of a possible 10 points because magazines that carry more than 10 rounds remain legal there. Also, the Brady Campaign prefers a different definition for an assault weapon. ""While it’s the state with the fifth strongest gun laws, obviously, at 58 points out of 100, there’s a lot more the state can do,"" said Brian Malte, a spokesman for the group. We found that groups that push for tougher gun laws consistently give Connecticut high marks. For instance, the San Francisco-based Law Center to Prevent Gun Violence ranked Connecticut fourth in its 2012 report, and fifth in 2010. It assigns points to each state based on 29 aspects of gun law, including the sale and transfer of firearms, owner responsibilities, and rules on their handling in public places. The center Georgia ranked 24th in 2012. And Mayors Against Illegal Guns, which boasts membership of more than 700 mayors, including Atlanta’s Kasim Reed, issued a 2010 report that compared states based on whether they enacted 10 key types of gun laws. Connecticut had put nine of the 10 types in place. Only New York and New Jersey received a 10 out of 10. Georgia had enacted two. Our conclusion:  Kingston is right on this one. Connecticut consistently ranks high in lists of states with stringent gun laws, and literally ranked fifth in recent rankings by the Brady Campaign and the Law Center to Prevent Gun Violence. Furthermore, he’s pretty close on the number of assault weapons banned in Connecticut law. Kingston earns a ."
Example Output:
Connecticut has the fifth toughest gun control laws in the country, including an assault weapons ban that bans 35 different weapons.
