pollution can kill you! so help stop pollution! it is very uncomfortable to breath in polluted air! even ask person #1!
"is pollution uncomfortable to breath in?" i asked.
"yes it is very uncomfortable to breath in air that smells like smoke and smog" said person #1.
pollution is in your very own home! when you use electricity you are polluting! when you do anything with machinery you are basically polluting! i am not saying stop using electronics.. just don't spend 24 hours a day with them.. go out side and breath in fresh air.. if pollution hasn't taken over your property yet!
so yah basically be good to your neighborhood! no polluting! woosh!

what will happen 10 years from now because of deforestation?
if everyone keeps destroying all of our trees we will not have anything left to breath! the animals we use for food will all die from no homes and no vegetation. everyone will die basically. so do you want that to happen? i think not! also ya know how scientists have created oxygen? well that is just unnatural! you cannot mess with mother nature! because of all this we need to plant more and more trees! and get rid of polluting factories! we need more hybrid factories! and if no one has invented that yet then someone will! do you all get my point?
say no to deforestation and any pollution at all!
say no to deforestation and any pollution at all!

Deforestation May Make Humans More Vulnerable To Infection
"The classical idea has been that people working or living close to the forest were at risk for the disease, but that view failed to consider such factors as quality of life and general level of health," said co-author Luis Fernando Chaves of the University of Michigan. "Contrary to what was previously believed, the more forest you have, even in a marginal population, the more protected you are against the disease."
The researchers examined county-level ACL case data from 1996 through 2000 for Costa Rica, a country in which approximately 20,000 acres of land are deforested annually to make way for cattle ranching and banana, mango and citrus fruit plantations. In addition to examining such factors as forest cover, rainfall, elevation, and percent of the population living less than five kilometers from the forest edge, the researchers also incorporated an index of social marginalization into their analysis.
This index, which takes into account income, literacy, level of education, average distance to health centers, health insurance coverage and other indicators of life at the margins of mainstream society, provides a single measure of quality of life.
The researchers found a strong geographic overlap between disease incidence and social marginalization that was not found between disease incidence and the other ecological variables.
"When we looked just at factors such as climate and the physical environment, we found no specific patterns with respect to the disease," Chaves said. "But when we looked at the social data, we found clear patterns according to marginality."
Putting everything together, the researchers discovered that in fact there is a relationship between ACL and deforestation, but it's not the simple, "less forest, less disease" relationship that previously was believed to exist. Instead, there's a complex connection with El Niño Southern Oscillation (ENSO), a periodic ocean-atmosphere fluctuation in the Pacific Ocean that is an important cause of inter-annual climate variability around the world and also influences disease cycles. In highly deforested counties, socially marginalized human populations are more vulnerable to ENSO's effects, and disease incidence actually is higher, the analysis suggests.
Dr. Chaves concluded that the "study calls for control efforts targeted to socially excluded populations and for more localized ecological studies of transmission in vectors and reservoirs in order to understand the role of biodiversity changes in driving the emergence of this disease."
The researchers are now planning on conducting similar analyses for other diseases, such as malaria, paying close attention to how climatic fluctuations, ecological factors, and patterns of biodiversity relate to human disease patterns.

deforrestation is murder!
when people cut down trees it's like they are killing themselves. because without trees we get no oxygen which every one knows lets us breath. that is what is keeping us alive. so for every tree someone cuts down we need to plant 5 trees to replace it. that will help us replenish our oxygen supply.
