Does drinking 3 cups of green tea daily for a prolonged period of time decrease the effectiveness of the birth control pills? i take yaz (drospirenone and ethinyl estradiol) for 2 years.

No: Drinking green tea 3 times a day does not change the effectiveness of birth control pills. Of course, no pills are 100% effective, so there is always a very small chance a woman could become pregnant while using birth control pills, regardless of whether she drinks tea or not. The healthier way to drink tea is without sugar or sweeteners.
