The environment on the island is harsh. It's where wild animals roam. Poisonous snakes lurking at corners that we don't expect. Wild monkeys trying to steal from us. We built our own little hut. Just enough to fit the lot of us in. We were lucky to have found a flowing river. One which we could get clean water to drink.
Food on the other hand, weren't much. For the vegetarians at least. All we could get was some bananas and coconuts. That was all that they could eat. The remaining ones realized that there are no cow or chicken or any other source of meat that they could usually get at the hypermarket. We soon realize that food has always been around us. Even surrounding us.
The rivers are full of fish. The seashore were filled with crabs and some never before seen bivalves. Insects are good source of proteins. Snakes, rats, wild boars and some other little mammals may all fill our stomach. But food is running low for the vegetarians. Seeing the very conditions that we were facing, I decided that remaining a vegetarian would only kill me. I have to go against my principles if I want to live. Adapting is crucial in order to live without much problem.
Even so, there were a few that insisted on their diet. They can't bear to turn omnivorous. They even went on their own way to search the deep forest for their own meals. Is it worth it to stand on such principles at such a difficult situation. I wonder if they survived. If it were you, would turn to meat despite you are vegetarian to survive? Would you go against your own stand, principles and beliefs to do what you need to live?
