Should you eat animals?
No, you should not. No matter how much you have a craving for it, don't! Animals were sent on earth for living not killing. Animals are good, not bad. They might attack you, but all they want you to do is leave them alone and let them live their life, not dying. You might think deer is an animal we can hunt, but it is not.
In a future world we will not be able to eat animals. Cattle cost too much environmentally (too much water, too much grain to eat, too much pasture, land torn up by their hooves, too much methane gas belched into the atmosphere). Methane is a greenhouse gas 20 times more dangerous than carbon dioxide. Water will be needed for humans, as will grain. Pasture land will need to be planted with trees and food crops to feed the population of the world. Two hundred years ago there were one billion people on earth. Now there are nearly 7 billion.
Even now we can do a little bit to counter global warming by eating fewer red meat dishes, eat more vegetarian meals, and eat chicken rather than beef.
You don't really need to look at it in that way. We need meat to not only gain energy, but also to grow and develop. We need meat to put muscle in our arms and strength in our bones. If we didn't have meat, we would be weak, physically and mentally, and we wouldn't be able to change much because we wouldn't have the strength to hunt.
If we didn't have meat, we wouldn't be able to reproduce, children would be dieing, children are because they don't have much to eat.
If humans never ate meat, we wouldn't have the energy to develop properly. Also, we would be living on the same level as animals, and not have the upper hand on the food chain. We could be living in small tribes as canibals for all we know!
And imagine what the forests and landscapes would be like. There would not be enough vegetation for us all, and the food chain would swing wildly off balance. If there isn't enough vegetation, we wouldn't have as many recources for shelter, food and warmth.
I'm not saying we should eat every single animal that we see, but we should be able to eat meat when we need to.
Animals should be free, I agree, but when we die the animals thrive upon the plants that grow on us, and if we eat animals they can eat us one day too (in a way).
The answer above, implicates that there will not be enough room for all of us because it costs too much to do so. But technology in getting better. Young and imaginative scientists are coming up with ideas waiting to be tested, and I'm sure that mankind is smart enough to come up with a solution.
It is inhumane to kill as many animals as poaching does, illegal poaching like whaling. If for example, we slaughtered as many animals as the Japanese do whaling (in addition to what everyone needs), of cattle, poultry, and other meats, then we would be on the threshold of disaster.
I understand many whaler do it so they have to money to feed their family, and may have no other choice, but the whaling that goes on should not come in such large quantities.
I have nothing against japan or it's country, because I think japan is a beautiful, but the only thing I don't like is it's decision to hunt in such large amounts.
So MY answer is that we have the right to eat what we need, but not over hunt like Japanese whalers do.
The ethical implications of a meat vs. vegetable diet is something everyone simply (or perhaps not so simply) has to work out for themselves. To some extent, this is also true of the health aspect. In both instances, however, I think we can safely conclude that the current model of treating and eating animals is highly unsatisfactory and inhumane. There are also many questionable implications to our health in consuming animals and animal products that originate in modern mass-production facilities or factory farms. My own conclusion, from the nutritional standpoint, is that if you choose to consume animals and/or animal products, is best to stick to high quality (usually meaning organic) products and in smaller quantities than is typical for modern American or Western diets. I think this decision alone, while not resolving the more complex moral questions, is a marked improvement over the status quo of the modern diet.
Answer: If it is your preference to eat meat (i.e. animals like chicken, cow, pig, etc.), then it is your choice, your right, and no one elses. If it is more convenient, satisfying, and healthy for you, then it's more than likely the best choice for you.
