what about the benifits of hemp fiber we spend more on importing it because its illegal to grow here,but we must have it because it simply cant be substituted when making materials. You know how animal protection and other people bitch about the damage of removing plants and animals from thier habitats. What about hemp and cannabis there must be an environmental impact from removing these beutiful plants. They have as much a right to be here on this earth as us maybee even more. I read somewhere once that an acre of hemp can produce as much oxygen as i think it was around 10 acres (cant really remember) but it was astounding how much air these plants can process into clean air even more than a full grown tree! on the dicovery channel thety were talking about making artificial trees that could do the same job BUT would COST BIG $$$$$. Why dont they just open thier eyes and see the soulution to the GREENhouse problem. + it makes a wonderful in between season crop and actually makes the ground more furtile.
