I agree with you both. Yet, another factor is the pollution in our body. Although my candida flared up big deal when I was - once more - given Antibiotics . I am aware now that my body was highly contaminated with heavy metals. THis toxic accumulation - paired up with repetitive Antibiotics treatment - seems to me the key element that causes the adrenals/liver over load leading to candida.
So yes, it is not only the entire planet that is in danger due to too much pollution, it is the human body as well.
