Yocha News- What was once forest within a few years could be transformed into a building and housing. Human civilization is often developed at the expense of environmental sustainability. Unfortunately, the less trees can exacerbate human health.
One study found an increased number of dead trees associated with the increasing number of human deaths due to heart disease and respiratory problems. Research conducted by the U.S. Forest Service is trying to examine the relationship between the health of people behind the death of 100 million trees in the East Coast and Midwest.
The researchers examined data on demographics, mortality and condition of the forest from 1990 to 2007 in nearly 1,300 regions in 15 states. Researchers looked at differences in health conditions of people living in an area filled with the ash borer beetle.
Apparently people living in an area where there are many weevils have heart disease death rates are greater, ie 15,000 cases a lot more. The death rate from respiratory diseases were also found 6000 more than other areas.
In a report published the American Journal of Preventive Medicine, researchers highlighted that there is a relationship between the less number of trees with high rates of human mortality, even after accounting for factors of race, income and education level. However, the study did not find a causal relationship.
"There is a tendency to look at our findings and concluded that the high mortality rate due to several factors such as income or education, not the death of the tree. But we see the same pattern over and over again in places where the demographics are very different," said the researcher, Geoffrey Donovan as reported by Medical Xpress, Thursday (14/02/2013).
Donovan explained that the bark beetles are emerald ash borer named was first discovered in 2002 near Detroit. 22 species of beetle attacks Ash trees in North America and killing all the trees they occupy.
