Plastic food and Plastic packaging

It seems that there is a certain and serious approach to reduce clear plastic packaging when it is not needed such as fruits, vegetables. Right movement indeed as our seas look full of rubbish plastic packaging which has been easily got rid off without second thought by us the civilised humans!

However we have been wondering why we have not tackled yet the ''plastic'' type food at the same time. Do we really know about the pesticides/chemicals used in conventional farming.
What we mean?
Why a normal snack bar has got 13 ingredients,
with some of them travelling thousand miles see palm oil, and
some of them are additives either chemical preservatives or other substances which are used for sticking ingredients together.
We have shortened our life expectancy by having so much stress from work, now we add extra loss by being fed the wrong things
Let's change chemical ingredients to organic and clean ones and where possible raw.
