Pesticides!

Pesticides are used to kill the crop invaders. These pesticides are sprayed on the crops where they remain. These crops are sold to the public and used in the production of animal feed and other byproducts.

The crops are the same ones we buy at market to eat. The bugs are gone but the chemicals are not. We are ingesting these chemicals which were used to kill living organisms.

These crops are used in the preparation of feed and produce which is marketed to humans. Animals are eating the byproducts and humans are eating the produce and both are retaining the chemical in their bodies. Then the humans eat the animals and get dosed again with the chemical. Humans have all these toxins in their bodies and are slowly being poisoned. And it's not just land creatures.

Washing and pealing don't clear it away completely. Washing doesn't get everything off. Still you need to wash all fresh fruit and vegetables to clean them as much as possible. Pealing doesn't get everything off because it can grow through the vegetables. The other problem with pealing is that many of the nutrients that we want from the fruit are stored in the skin, so pealing reduces the benefit to your body.
