Anyone else heard about the 'planetary health diet.'?

I didn't hear that. What does this mean?

Is it what you feed your planet to keep it healthy and reduce the number of parasites infesting it?

A bit of meat, a lot of veg - the flexitarian diet to feed 10bn
By James Gallagher

Scientists have been trying to figure out how we are going to feed billions more people in the decades to come.

Their answer - "the planetary health diet" - does not completely banish meat and dairy.

But it is recommending we get most of our protein from nuts and legumes (such as beans and lentils) instead.

Their diet needs an enormous shift in what we pile on to our plates and for us to turn to foods that we barely eat.

What changes am I going to have to make?
If you eat meat every day then this is the first biggie. For red meat you're looking at a burger a week or a large steak a month and that's your lot.

You can still have a couple of portions of fish and the same of chicken a week, but plants are where the rest of your protein will need to come from. The researchers are recommending nuts and a good helping of legumes every day instead.

There's also a major push on all fruit and veg, which should make up half of every plate of food we eat.

Although there's a cull on "starchy vegetables" such as the humble potato or cassava which is widely eaten in Africa.

A piece of land that feeds one meat eater can feed several vegetarians. Ok. What will happen next? I think that population growth will eat all the effectiveness of this way. We can get fifty billion vegetarians and get back to the question of efficiency. Key questions are: how much resources should humanity leave to nature? And how can we control the population?

Not always. The US has locations which are not suitable for growing crops but can graze cattle or other animals and produce food that would not otherwise be consumable by humans.

Which is the real question as there will always be a finite capacity for supporting a population independent of what that population is ... human, cattle, deer, hogs, dogs, or birds.

I am trying to draw a simple model to show the general principle. We have a limited region of our planet and a limited energy of our Sun. For example, a hundred dogs or fifty dogs and ten people or twenty people and zero dogs can live in a certain area. If we want to save animal species, we have to decide: how many resources should we leave for wildlife? The second part: this area can feed twenty people without any luxury or ten people with a good home or one person with a good home and a good car, etc. I don’t show real numbers, this is just for comparison.

I am not a primitivist, and I do not think that people should throw away science, grow new tails and climb trees. I think, this way is a repetition.
