Q: Croatian air pollution levels reflect the drop in industrial production recorded in 1991 at the onset of the Croatian War of Independence—pre-war emission levels were only reached in 1997. The use of Hydrodesulfurization fuels has led to a 25% reduction of sulphur dioxide emissions between 1997 and 2004, and a further 7.2% drop by 2007. The rise in NOx emissions halted in 2007 and reversed in 2008. The use of unleaded petrol reduced emissions of lead into the atmosphere by 91.5% between 1997 and 2004. Air quality measurements indicate that the air in rural areas is essentially clean, and in urban centres it generally complies with legal requirements. The most significant sources of greenhouse gas (GHG) emissions in Croatia are energy production (72%), industry (13%) and agriculture (11%). The average annual increase of GHG emissions is 3%, remaining within the Kyoto Protocol limits. Between 1990 and 2007, the use of Ozone depletion was reduced by 92%; their use is expected to be abolished by 2015.

In the first quarter, Carolina pounced first with QB Jake Delhomme hooking up with WR Steve Smith on a 7-yard TD pass and a 12-yard TD pass. The Texans would respond with QB Matt Schaub completing a 31-yard TD pass to WR Andre Johnson. In the second quarter, Houston continued its pounding with Schaub and Johnson hooking up with each other again on a 9-yard TD pass, along with kicker Kris Brown's 25-yard field goal. In the third quarter, the Panthers continued to struggle as Texans RB Ahman Green got a 13-yard TD run, while Carolina FB Nick Goings fumbled during a kickoff return. The ball would roll into the endzone, where Houston WR Kevin Walter would land on it for a touchdown. In the fourth quarter, the Texans would put the game well out of reach with Brown's 33-yard field goal. The Panthers tried to get a comeback with Delhomme and Smith hooking up with each other on an amazing 74-yard TD pass, but the deficit was too much to overcome.

Q: Following their victory over the Patriots, the Steelers remained at home the next week for their second match-up of the season against division rivals the Baltimore Ravens.  The Ravens scored first with an 18-yard field goal by kicker Billy Cundiff, the only points scored in the first quarter by either team.  Steelers kicker Shaun Suisham answered with a 36-yard field goal early in the second quarter, and a 30-yard field goal near the end, but both of these were quickly matched by Baltimore's Cundiff with a 43-yard and 51-yard field goal, respectively, giving Baltimore a 9-6 lead at halftime.  The Ravens then increased their lead in the third quarter when Ray Rice scored the first touchdown of the game on a 4-yard run.  The Steelers rallied hard in the fourth quarter, with running back Rashard Mendenhall making a 1-yard run to score a touchdown, and then taking the lead for the first time in the game when quarterback Ben Roethlisberger made a successful 25-yard pass to wide receiver Mike Wallace in the endzone for a second touchdown.  On their final drive of the game, the Steelers were ready to potentially increase their lead with a 47-yard field goal kick by Shaun Suisham, but a 5-yard delay of game penalty put them out of field goal range and they were instead forced to punt the ball to the Ravens.  The Ravens then began a 92-yard drive, culminating in a 26-yard touchdown pass by quarterback Joe Flacco to wide receiver Torrey Smith in the endzone with just 8 seconds remaining, giving them the game.
