Dirty Dozen...a good guide when you are transitioning to organic produce

I have been trying to buy organic produce, when possible, in an effort to eat better. I was doing research on organic produce and came across a reference to the Dirty Dozen. The Dirty Dozen is a shopper's guide to the 12 fruits and vegetables that are loaded with the most pesticides. The list is put out by the Environmental Working Group.
The EPA's website says:
What is the balance between the risks and benefits of pesticides?
By their very nature, most pesticides create some risk of harm - Pesticides can cause harm to humans, animals, or the environment because they are designed to kill or otherwise adversely affect living organisms.
At the same time, pesticides are useful to society - Pesticides can kill potential disease-causing organisms and control insects, weeds, and other pests.

I was surprised to see that produce I eat every single day is on the list.

Dirty Dozen (buy organic when possible) :
1. (worst) Peaches
2. Apples
3. Sweet bell peppers
4. Celery
5. Nectarines
6. Strawberries
7. Cherries
8. Kale
9. Lettuce
10. Grapes (imported)
11. Carrots
12. Pears
