Please  help make earth friendly products affordable

How can we get manufacturers to lower the price of the  EARTH FRIENDLY PRODUCTS, such as cleaning supplies, paper towels, toilet paper, kitty litter,and so on,,,,and the Automobile Manufaturers, there are some awesome vehicles out there, hybrid or not, that are getting fantastic milage, but most  of us cant afford,..it does not make sense to me, when i go to health food stores, and the organic grocerys, cleaning supplies etc, are twice or 3 times the price of regular items we can purchase else where, I personally think if the prices were more reasonable, more folks would get on the band wagon and it could educate people as well, that have'nt thought much about it prior,
