I have been studying the quality of food grown the last few years and the effects of poor and lack of nutrient dense soil. the impact it has on the quality of food you produce. Since then I do not use roundup at all in my yard front or back. In this section I will link some of the resources I personally have read on and used myself for those interested in improving the quality of food grown from improving the quality of soil that you use.
Even if you have no desire to grow your own food it is still good to research how awful these chemicals are to our planets foundation. How these chemicals are water soluble and get into everything.
These are two excellent documentaries and worth the time to watch.
something else that is just as important as the foods you put in your body is the products we use on our skin and the clothes we wear.
