What is a problem that is created by ethanol as a biofuel?

A problem that is caused by use of ethanol as a biofuel is that crops which could be used to feed people are used to provide raw materials for biofuels.  This could cause food shortage or increase the price of food.

In addition, large tracts of land  have to be used  to grow large amounts of crops to produce ethanol. There is concern that more land will have to be cleared in order to grow more crops to satisfy increased demand. This could lead to the destruction of important ecosystems and cause erosion. 

the california missions began in the late 18th century as an effort to convert native americans to catholicism and expand european territory. there were 21 missions in all, lasting from 1769 until about 1833.   the missions were built by the spanish starting in 1769 in order to “colonize” the territory of alta california. so the missions were important because they were the means of settling california. it also wanted to keep other european countries out of alta california. building settlements along the coast would them meet these goals. missionaries wanted to convert the indians to the roman catholic faith. california indians did much of the work to build missions.
