A Numbers Problem
For every non-human carnivorous predator on Earth there are about 4,000 human self-styled omnivorous predators…who nonetheless want to believe they are civilized, ethical and loving. But a massive number of land predators (including omnivores like bears) simply makes zero sense and goes against nature’s very efficient system of food supply. There are no large masses of bears in nature either, their being omnivores who kill and eat meat when available. Think about it. Imagine if these were lions or bears instead of wildebeests…
A herd of 10,000 breeding/reproducing meat eaters in a region would eventually devour all of their food supply and then wipe themselves out, especially when resorting to cannibalism to survive. Imagine an ocean full of billions of sharks. How long would that last before everything died off? Unless those sharks adapted to plant eating somehow. In that case they could survive indefinitely until their population got so out of control that plant growth couldn’t keep up with their needs. Until a predator showed up that could get their numbers down. Back to the old vicious cycle (predator vs. prey), which humans want no part of in their nice civilized lives, except for when they’re doing all the killing, that is.
A Sustainability and Moral Problem
Humans think they have the solution to the numbers problem by farming “their own” animals and slaughtering them, taking their milk and eggs, skins, their whole existences, their lives…everything they’ve got, and then some. Nightmarish in its scope. People want to overlook the fact that those animals must be fed, watered, their huge amount of waste dealt with, the illnesses associated with the confinement and filth dealt with through antibiotic abuse, and on and on. None of it honorable or showing true human intelligence. All in all, animal farming uses up far more resources than any crop farming ever could. Not to mention the moral and ethical toll it takes on us all as a “humane” species. All this also goes towards explaining humans continually preying upon each other, which again reminds me of the ocean full of sharks mentioned above.
Hunters like to say theirs is the solution, as if 7 billion+ humans feeding on every “edible” animal out there makes any more sense than farming does. But that’s another issue.
A Lifespan Problem
Omnivorous and predatory birds are one exception to the population rule because they travel vastly from place to place and are also taken as food by predators including other birds, so while their populations can be large, they never get too numerous for their own good. Birds live on average about 30 years, while predatory land animals live about 13-20 years, while much larger
African elephants (vegetarians) live about 65 years. The rougheye rockfish (a carnivore) is probably the longest living species on Earth, to about age 205, but they’re largely solitary or form small groups (schools) only at mating time. A huge population of a long-living, meat-eating, relatively large in size/scope species like humans simply is not sustainable for the long term on planet Earth. As we can see by all the serious problems caused by our animal agriculture practices.
A General Problem
Humans live on average 70-75 years and by nature tend towards huge populations (compared to other animals). We’re now 7 billion plus. Other life forms may be far more in numbers (ants for instance), but have nowhere near our huge “footprint” on the planet, with all the land mass taken up by humans, all our manufacturing, buildings, massive resources used, pollution caused, exploitation and killing of other species, etc. Except for parasites, other species serve vital needs in nature, as in ants, earthworms and flies who serve as the clean-up crew, dealing with dead bodies and other unsanitary waste, with earthworms making for rich soil, vital for plant growth. While humans mostly create polluting waste and largely benefit only our own shortsighted needs.
I didn’t want to get into charts and graphs, etc., here but just to make a simple point: We humans, with the way we want to live, have really no excuse at all to continue trying to be Earth’s “apex” predators. Our bodies and our most desirable psychological makeup, and notably our large and insatiable population, are far more suited to crop farming and eating only plant foods. And most of all, we’re suited to treating the other species and thereby ourselves only with respect and care. That would prevent our exploiting, harming and killing animals and ourselves any longer.
