AAA reports that Americans paid an average of $2.40 per gallon of gasoline in 2015, which is 94 cents lower than last year - but not as low as the projections for next year.
Isosporiasis is a disease caused by the protozoan Isospora belli. The organism infects the lining of the small intestine and can cause severe diarrhea and malabsorption (an inability to absorb nutrients). Isospora belli is spread by feces. Food or water contaminated with animal feces may carry this organism; it's also possible that oral-anal sex may spread the infection. On occasion, there are outbreaks of isosporiasis that can be traced to a feces-contaminated water supply.
The greenhouse effect is caused by the interaction of the sun's energy with greenhouse gases such as carbon dioxide, methane, nitrous oxide and fluorinated gases in the Earth's atmosphere. The ability of these gases to trap heat is what causes the greenhouse effect.o the more greenhouse gases you have in the atmosphere, the more heat stays on Earth. If the amount of energy from the sun and the amount of greenhouse gases in the atmosphere remain the same, then the average temperature on Earth will also be constant. But this is no longer the case.
