Most of us are aware of what global warming is and its consequences. Apart from all scenarios predicted by environmetalists or other scientises or even plans that some politicians put forward, there seems to be another reason why global warming may have a negative impact on our planet and life on it. A recent article titled: Lesson from America’s tropical epidemic claims that global warming may cause spread of harsh diseases such as the yellow fever, “as the range of where mosquitoes, ticks, mice and other carriers of disease can live expands” (26/02/2008).

"It's a very ugly disease — things like eyes bleeding, nose, ears, some pretty gruesome symptoms," Crosby says. "But then it also causes internal bleeding. And one of the telltale signs of yellow fever is what they call 'black vomit.' It's from digesting internal bleeding." (26/02/2008)

Our precious Amazon rainforest really needs looking after – this is very common knowledge. Even though we seem to realise this, lots of changes are still being made in the Amazon and apart from the loss of the valuable trees, it has recently been discovered that building new roads not only promotes deforestation but also spreads malaria!!! (25/02/2008)

“New roads promote deforestation. A recently published survey of the Peruvian Amazon by Paulo Oliveira of the Carnegie Institution of Washington and several colleagues shows that 75 percent of the forest disruption that occurred between 1999 and 2005 occurred within 12 miles of a road. And deforestation promotes malaria — researchers Amy Vittor and Jonathan Patz surveyed a newly constructed road and reported in 2006 that the areas along the road that had suffered more deforestation also suffered more malaria. “ (25/02/2008)
