You cannot really believe what you wrote can you? Lets look at hemp.
First a paper source,it is true hemp makes a supior grade of paper. But has been and will be a specialty paper
not one for general use. One reason is the labor intesiveness of
processing it. This is also true for the cloth. As far as being able
to provide for all our energy needs,you cannot believe there are enough acres of land
in the US to produce enough hemp oil to replace all the petroleum
used can you? We currently make bio deisel from soy beans and have
hundreds of thousands of acres planted and still it makes only
a small dent in our use of fuels. Also you can cultivate hemp for
the oil or fiber,but it does not work to use both from the same plant.
