Second Week Health Factors

Health Factors
And by using synthetic material, we humans damage our health.
I also learned that synthetic vitreous fibres, which are used as a replacement for asbestos, if repeatedly breathed in, can worsen the effects of smoking. They are also possibly carcinogenic to humans.These fibres are for example used in isolation or in ceiling boards (http://www.atsdr.cdc.gov/phs/phs.asp?id=906&tid=185).

There is evidence from scientific research that the components of plastic are harmful to people and the environment. When being produced and disposed, plastic creates problems like:

-components of plastic can alter hormones and effect human's health negatively
-plastic floating on water can be eaten by sea animals, which harms their health and thus wildlife
- this floating plastic can also transport harmful bacteria or other microscopic creatures and thhereb threathen stable habitats.
-this plastc waste stays intact for thousands of years
-plastic contains harmful chemicals which can contaminate groundwater.
