If there were no Non-Vegetarians on the Earth,the Vegetarians would go Hungry !
You see the herbivores we consume, would have eaten up all your Food.
So for Balance on Earth,in the Ecosystem, in our Lives,Non-Vegetarians have a great role to play.
God has His way to sustain life,to provide for all His Creatures.
Be Thankful.Complain Less.Be Happy.
