So, is GMO helpful or harmful?

My opinion will be that it is harmful. I mentioned the advantages and the disadvantages,
I think in some poorer countries it'll help. because it makes it cheaper and it allows people to get food supplies easier.
But in countries like Japan, United States, richer countries there should be labels on it or else no one will buy it. 
and I believe that animals should be the way it naturally is. Organisms develop there selves like humans did. 
for example dogs. many dogs are Genetically Modified, like poodles 
a normal standard poodle would look like this;

In Japan people buy small dogs rather than big dogs. 
Tea cup poodle was made because normal poodles are too big. 
this is one example of animals being genetically modified because of
humans. 

So I think GMO is harmful.
