Of course over cloning of livestock produces environmental problems such as decreasing o-zone levels due to the increase of methane gas. At the minute its one of the main causes for lowering o-zone levels but if we start to clone animals then we end up making matters worse by raising methane levels.
Nobody looks further than solving world hunger which it wouldnt because there is already enough food on the planet to end world hunger but of cource it has to be sold (in other words poor countries get nothing and wont ever get anything).
