Many humans think that killing and eating animals like cow or goat are unethical practices. I completely agree to this statement. As number of animals in nature are decreasing which causes imbalance and eating meat can sometimes leads to food poisoning.
If animals like buffalo or hen dies by natural death it doesn’t create any problem, but when humans start killing them and eat them, then it creates a disbalance in environment. This can cause into natural disaster in coming years. If the habitat of any species starts to extinct on planet then it leads to nature problems. There are other reasons why some people do not eat meat as they believe it is not ethical and they are compared to god and worshiped in many parts of world.
Some flocks disagree to accept meat as their food because they had a bad experience while eating. Some meat, if not properly cooked then it can lead to food poisoning. Uncooked or diseased food causes illness, and it is dangerous to consume those type of meals. In many parts of country, people often gets sick due to bad diet. For example, a friend of mine who resides in America was fond of eating chicken on daily basis. Without meat his meal was incomplete, but one day when he ordered beef from local shop, he got sick and was admitted to hospital. From that day till now he hasn’t touched beef.
To conclude, many believe that forcefully killing and consuming animals is bad practice as it leads to loss in particular species and also leads to food sickness.
