Typical. Righties can't give Obama credit for anything, ever. It's not in your DNA.
Hi Robbie...
Yes we exhale CO2, and plants breath it in. There has always been CO2 in the atmosphere. The problem though, is that today there is a lot more of it, and soon there could be too much CO2. Plants and trees are very effective at sucking the CO2 in and pushing it into the ground, but deforestation and urban expansion are reducing the how fast CO2 can be absorbed.
I mention clean water because increased global warming means increased drought. California is in serious trouble already.
However, too much CO2 in the ocean is causing Ocean Acidification. When CO2 dissolves in sea water it increases hydrogen ions and decreases the pH level, which damages corals, which form the habitat of approximately 25% of marine species.
I don't mean to drive you away man, I'm sorry... but this comes from NOAA.
The markets + supply and demand is what controls the price of energy, not the government or the president.
What's up (and down) with gasoline prices? - FAQ - U.S. Energy Information Administration (EIA)
What hurts poor people the most isn't just high energy prices. It's lack of opportunity, access to education, crime, health, lack of proper social assistance, and of course the export of job opportunities to other countries etc, the list goes on.
Peace...
