Lady animals figure very largely as predators.

That animal feeds on flesh.

The predator smells the bait, sneaks up... and he's caught!

The predatory beasts take over.

And they go in the base of that pyramid, and they drift up they're passed up that way, on to predators and on to the top predators, and in so doing, they accumulate.

Arboreal Predators of the Brazilian Rain Forest.

That paper deals with the instincts of predators.

Like a lot of predators, they walk on their toes.

Less meat, less junk, more plants.

This is the top carnivore, the T Rex of its time.

So how are these fish, these predators going to help?

But there's a very simple little kind of calculation of what's required, how much plants are required for the herbivores to live, how many herbivores for the carnivores to eat, etc., that you actually have to balance actively.

Meat, junk food, cheese the very stuff that will kill you.

Less meat, less junk, more plants.

So I went to Al Dunlap's grand Florida mansion that was filled with sculptures of predatory animals.

The good news is that, in addition to having more predators, there's more of everything.

Which bring me full circle and points directly to the core issue, the overproduction and overconsumption of meat and junk food.

The Tasmanian devil is predominantly a scavenger, and it uses its powerful jaws and its sharp teeth to chomp on the bones of rotting dead animals.

But not many people know that there actually is a real animal called the Tasmanian devil, and it's the world's largest carnivorous marsupial.

First of all, your pyramid, your inverted pyramid, showing 85 percent biomass in the predators, that seems impossible.

And then we have a lower biomass of carnivores, and a lower biomass of top head, or the sharks, the large snappers, the large groupers.

Here's an octopus. Sometimes they don't want to be seen when they move because predators can see them.

The weak are food for the strong.

But back to animals and junk food.

We could much better change from meat, from beef, to insects.

And that huge load was passing into the people that ate this meat.

Overconsumption of animals, and of course, junk food, is the problem, along with our paltry consumption of plants.

But the small animals that eat insects are being eaten by larger animals, still larger animals.

And now this brain takes care over this, to move it with the muscles and to do defend the surface and, of course, digest our food we cook.

A trout is a predator.

What shall they eat?

And at the end of the food chain, we are eating them as well.

Now, uncertainty is a very bad thing. It's evolutionarily a bad thing. If you're not sure that's a predator, it's too late.

Their diet consists of bananas and other fruit and the meat of animals which they hunt and kill with arrows their dwellings have roofs made of plastic, all of them torn.

When our ancestors moved out of the African forest onto the savannah more than a million years ago, they rapidly became effective predators. Sharing prey with pre existing carnivores, they acquired tapeworms that originally inhabited only hyenas, large cats, and African hunting dogs.

These animals feed on grass.

Who needed it though? Meat was everywhere.

We all know the arguments that being vegetarian is better for the environment and for the animals but in a carnivorous culture, it can be hard to make the change. Graham Hill has a powerful, pragmatic suggestion Be a weekday veg.

And they looked at the herbivores. And they weren't savanna herbivores.

Always leave the lights on.

Bearing the raw meat home from the kill in the jungle.

We are the animals who eat cooked food.

Hmm. Feeding time at the zoo.

These bacteria in turn support a variety of worms, mollusks, crustaceans and other animals.

Therefore if food causes my brother to stumble, I will eat no meat forevermore, that I don't cause my brother to stumble.
