Organic food sales increase, putting figures before our health

Globally, it seems that organic food sales have gone up year after year. We have been wondering why we need to put the figures first before our health in order to see organic foods consumption increase.
Why we need to reach the soil ''death'' by having a massive concentration of toxic pesticides, herbicides and heavy metals into it when conventional crops are cultivated.
 
Organic products do not need to be sprayed with toxic chemicals to be protected from diseases. There are numerous studies about the serious health risks when non-organic foods products are consumed. Toxins and heavy metals are concentrated in fat cells and tissues by eating foods of non organic farming. Washing the fruits before eating is not enough anymore, needless to say that you can not rinse off any chemicals from a ready meal.
It is intriguing to check the increase of cancers vs the consumption of conventional food. Apart from chemicals in our foods, these toxic substances remain in the soil for years or rinsed off by rain. The latter phenomenon may lead to the sea and rivers pollution while the former leads quickly to soil quality deterioration. Lowering soil quality means no cultivation of anything at all after a few years.
