Plastic Packaging, Food Packaging

Lately, it circulates everywhere the toxicity of plastic packaging, particular in food industry but also for household use.
At the end of 2013, a scientific study was brought in front of public opinion stating that 60% of cancer cases are due to food packaging , a frequent use of plastic packaging in everyday life and their high toxicity.
What really pisses me off is that only now, after decades in which consumer market pushed us towards to a frequent use of plastic packaging in everyday life, scientists wake up and say that are toxic and poison our food, blood,etc...
I wonder, the food preservatives or chemical fertilizers used in agriculture do not have the same effect?!
Am the kind of person concerned about a healthy lifestyle, but I'm also realistic.
Is there anything left, truly natural (ECO), in mass production?!
I am willing to know others opinion on the matter; do you, guys use plastic packaging, have any preference about the suppliers?
