Human Impacts of Man–made Chemicals
=>
The last 50 years has seen an enormous increase in the production and use of chemicals. This has led to an increased number of man-made substances finding their way into the environment, not just from industrial chimneys and effluent pipes, but also from products commonly used in the home.
As a result we all now carry a mixture of many different chemicals in our bodies. Of those chemical pollutants found in human tissue, a significant number have been shown to lead to effects on the health of various d i ff e rent animal species, including mammals. These effects include cancer, deformities of the re p roductive system, weakened immunity and behavioral disorders. Over the same period the incidence of some of these diseases in humans, including cancer and re p ro d u c t i v e system disorders, has increased dramatically. It is not possible with the scientific tools currently available, to know to what extent chemical pollutants are responsible for the increase in these diseases.
As well as increased exposure to a greater number of chemicals, there have been other changes over the last 50 years. For example, changes in diet and lifestyle could be having an influence, and it is impossible to separate possible effects of these ‘confounding factors’ from effects of chemical exposure. This uncertainty about cause and effect is c u rrently used by politicians as a reason to avoid taking action to protect people fro m chemical exposure. Chemicals are used in all s o rts of ways and are allowed to accumulate in our bodies, because direct proof of damage to human beings is not available.
This is upside down logic. We should not wait for proof that chemicals have harmed people before taking action on substances whose intrinsic pro p e rt i e s give cause for high concern. However, there are now moves afoot to bring chemicals under control. In 2001 the EU proposed legislation that would reverse the burden of proof (a chemical would have to be shown to be safe before it could be made) and make sure the world’s most hazardous chemicals were phased out and replaced with safer alternatives. 
It now appears as though that promise will be broken. This report highlights some of the reasons why it must not be broken. Because the chemical industry is using its economic might to persuade the EU to allow it to continue exposing us all to toxic, persistent and bio accumulative chemicals, EU citizens must fight for their right to an environment free of these most hazardous of chemicals.

Genetically modified golden rice falls short on lifesaving promises

Genetically modified golden rice falls short on lifesaving promises Date: June 2, 2016 Source: Washington University in St. Louis Summary: Heralded on the cover of Time magazine in 2000 as a genetically modified (GMO) crop with the potential to save millions of lives in the Third World, Golden Rice is still years away from field introduction and even then, may fall short of lofty health benefits still cited regularly by GMO advocates, suggests a new study. Full story- "Golden Rice is still not ready for the market, but we find little support for the common claim that environmental activists are responsible for stalling its introduction. GMO opponents have not been the problem," said lead author Glenn Stone, professor of anthropology and environmental studies in Arts & Sciences. First conceived in the 1980s and a focus of research since 1992, Golden Rice has been a lightning rod in the battle over genetically modified crops. GMO advocates have long touted the...

Did you know??You come into contact with chemicals every day!

Did you know??You come into contact with chemicals every day! This is called chemical exposure. Although some chemical exposures are safe, others are not.  A certain amount of a harmful chemical must enter your body to make you sick. Harmful chemicals can get into your body if you breathe, eat, or drink them or if they are absorbed through your skin. People respond to chemical exposures in different ways.  Some people may come into contact with a chemical and never be harmed.  Others may be more sensitive and get sick.  Sometimes illness happens only if you are exposed to a harmful substance for a long time.  Many factors play a part in whether you get sick from contact with chemicals, including  • The kind of chemical you are exposed to , • How much of the chemical you were in contact with, • How long the contact lasted, • How often you were exposed, • How it entered your body, and  • Your health. So be aware and stay healthy ...

Got sleep? The amount you get could affect your marital mindset

Got sleep? The amount you get could affect your marital mindset Date: August 6, 2016 Source: Florida State University Summary: A new study found that when husbands and wives get more sleep than on an average night, they are more satisfied with their marriages, at least the following day. Full story- The research was conducted by FSU Psychology Professor Jim McNulty and graduate student Heather Maranges. "The universality of our findings is important," Maranges said. "That is, we know all people need sleep. Regardless of the stage at which a couple is in their relationship or the cultural context in which they're embedded, each member of the couple can be adversely affected by not getting enough sleep." The paper, "The Rested Relationship: Sleep Benefits in Marital Evaluations," was published in the July issue of the  Journal of Family Psychology. It highlights the significance of sleep as it relates to self-regulation or self-control, w...
