Regarding there not being enough vegetation to feed 7 million people.... The animals themselves have to be fed on grains,corn etc grown of the earth.
If meat can be mass produced then that meat in its life needs feeding.
Surely that food that is fed to them could be used to to feed people, corn and grain could go a long way as animals themselves would not be in the numbers they are now in any way.. as they would not be needed to be mass produced and artificially bred. Nature would naturally select.
Also, if animals can be mass produced for food this can be easily done with crop surely in most areas of the world. Orchards etc.
The fact is humans can live off a variety of plants and vegetation. Some of the things we are not even familiar with, if society was different it would be more known. Even remote places have something, the earth is plentiful and full of nutrients and goodness in the strangest places.
I call it human lack of intelligence on the subject on a mass scale (or just the love of the taste of meat) that takes the enquiring mind away from studying nutrition and how to find it.
People will sooner head to a burger bar than read a book on the nutrients of a tree or plant.
It is society to blame....they have distorted peoples natural way of thinking from the beginning of time and replaced it with nonsense and multi million pound organisations of corruption, greed and cruelty regarding our food.
It is the mindset of the person that is in question , the motive and the reason.
Hunting for fun I do not agree with..this is cruel....factory farming is cruel.
As for farmers trying to scratch a living?
I dont think I have ever seen a farmer who truly cares for their 'animals' at all...they care for the money that their flesh will bring...
....... but this is when the spirit of a person(the farmer) comes through,,, and the measure of the man (or woman ) I feel...
How does one claim to care on a farm for their livestock and then pack them off for slaughter without a second thought....
where is the compassion for the poor beast that looks into your eyes as you load it onto the slaughter truck when there is a tree full of apples in the next field. Some even name their animals...talk to them...and as cold as you like send "Old Berty"to be killed without the blink of an eye...some even eat them themselves.....to me this is beyond comprehension.
You may say I look at it too simplistically but if this thinking was widespread there would be less health problems, the right amount of animals in the world in their natural native countries and less violence and negative vibrations due to animal murder on mass scale and the consumption of slaughtered flesh.
I still stand by what I have said all along.. love and compassion for all living things is the basis of spirituality.
I wish you well
