I was never a person too much concerned about the quality of the food I am eating, actually I do not like very much to stay with people who are worrying all the time about the kinds of poison they might have in their meals. I always thought, the most dangerous poison is a poisonous thought. Therefore, why I care about environment is not because I worry about my nutrition but because I like environmentalists. I like people who care about the consequences of their actions, I like people who consider nature as sacred, I like people who care about global equity and environmental justice.
But after I bought my weekly portion of bottled drinking water yesterday, and I had nothing else to read but reading the bottles, I must say I was surprised. The nitrate content of my bottled water - the probably best quality I can get in this - well not quite pristine, but nevertheless somewhat rural -place was 80 mg/l, meaning 30 mg/l more than would be allowed in Germany! And I remembered of times when my attitude was different. That was after my eldest daughter was born and our forest were dying of acid rain. Then I was scared how my daughter could breathe without a forest, I took information, and the solution which was suggested was to lime the forests. Liming on the other hand, I was reading, would lead to an increased mineralization of organic substance, which would end up as increased loads of nitrate in our drinking water. Nitrate is not a very nice ion, it can cause cancer, and before becoming nitrate, however, the soil born nitrogen becomes nitrite and under certain conditions stays as such for a longer time than normal. These were the time when several babies suffocated from too much nitrite in the water. Sudden child death. Then I panickedly ran to my daugter's bed, she still was alive, and I continued reading articles by articles how to avoid too high rates of nitrate and nitrite in drinking water. There did not seem to be a way out. Then I wrote a thesis on nitrate in groundwater. These were the times when daily about 50 scientific articles were published on nitrate in drinking water. By and by the Germans and all Europeans managed to reduce their nitrate loads to their groundwater - I am afraid even without consulting my thesis.
But here, I do not know, who would care. I think the reason is the high livestock population and uncontrolled manure lying around everywhere. Then I told my Dean that I was worried about cancer in their societies. But the Dean answered, there is hardly any cancer, despite those high nitrate contents in the water, nobody would be aware of anyway. He said, because they have extended families and are always surrounded by many of their beloved ones. I think he is right. Beloved ones around reduce the risks caused by high rates of nitrates, I am sure.
