For anyone who had biology or an environmental class in high school, you're probably somewhat familiar with this term. Biological magnification is defined as a trophic process in which substances in the food chain become more concentrated with each link of the food chain. In a simpler statement, it's the accumulation of toxins as you go higher up the food chain. Indeed, not too good for whoever's at the top of it all.
Wait a second. Gasp! We're at the top.
Let's check out an example.
- A farmer sprays pesticides all over his crops.
- Not all insects are affected by the pesticides he used, so they still continue to eat his produce.
- The insects are later eaten by a chicken that is allowed to roam freely. Of course, to satisfy his hunger, he eats many of these toxic insects (which accumulates in its body).
- You have chicken breasts for dinner, and the toxins now accumulate in your body.
There's a reason to be eating organic. Eating foods involved with all these chemicals over a long period of time can't be good for you because they will build up in your body.
Humans eat a lot. No doubt about it and that's ok. But, there should be an increasing importance placed on getting enough organic foods into your diet and supermarkets need to be supplying the consumers with them.
