Most of the Lake District:
Geology: 9/10
Ecology: 2/10
It's overgrazed to smithereens by sheep.

Look at this view of Great and Green Gable. You cannot see a single tree or shrub. The sheep have eaten everything.
We hiked for 8h on a sunny April day - I don't think I saw a single flower or insect on the peaks.

Aha! Found some trees!
They're growing on small ledges on cliffs near the stream with little grazing pressure.
Well done little guys.

Mid April in the UK, anywhere green should be thrumming with birdsong.
All I heard was a few wrens, crows and I saw some stone chats.
Not a single person on the peaks had binoculars out.
It's desolate, it's depressing, it's barren.
Our hills and mountains deserve wildlife.

In the Lake District, there are National Trust donation boxes asking us to help conserve the Lake District.
@nationaltrust - your emblem is literally an oak leaf - why would we want to conserve these unnatural, treeless landscapes?

I often see more interesting vegetation along A roads and motorways than I do in much of our uplands and national parks.
This is such a crying and unnecessary shame.

Here's a photo from the car driving home from the Lake District: trees, shrubs, blossom!

Yes, grasslands with low levels of grazing are important ecosystems for wildflowers and insects. That's not what most of the Lake District is.
Here's a photo of Martin Down nature reserve: there's shrubs and trees and birdsong and butterflies and orchids galore.

Overgrazed uplands like the Lake District are often referred to as High Nature Value farmland.
Here's the view of a Cambridgeshire wheat field from my garden. There's more flowers, insects& bird song in this high yield farm& adjoining gardens than in many upland national parks./8 View from a Cambridgeshire ...A photo of the lake Distric...
We did find a beautiful and nature-rich spot in the Lake District, which is the flagship, wilding scheme by Ennerdale Lake, @wildennerdal
Have a look at this thread for some joy and optimism!

Some people have rightly pointed out that I'm comparing photos from different sites at different latitudes and altitudes.
Here's a great article showing the change in vegetation within enclosures where intense grazing is reduced in upland areas. /10

I am over the moon we're on the front cover of @bmj_latest !
Our article: How could we enable low carbon behaviours to reach #NetZero for food & transport?*

*more plant-based diets, active travel & public transport; less driving.

💡Diet and land travel are key sectors for health and sustainability
⛽️Food production is 26% and land travel 12% of global GHG emissions
⚰️Outdoor air pollution leads to more deaths than HIV&malaria combined:

Current govt policies are insufficient to rapidly decarbonise & reach #NetZero
We need policies led by evidence and citizens' values. Citizens' assemblies often recommend more ambitious climate policies than govts'.

Crunching some numbers:
🚄#HS2 's construction is 8-14 million tCO2 (~12)
🔌1 electric car (Nissan leaf)'s construction is ~10 tCO2
🚘The UK has ~44.5 million petrol&diesel cars
🤯Replacing them all with EVs would take 445 million tCO2 or *37* HS2s
🚉HS2 = 1.2 million EVs
/1
For context, 10t CO2 = 1 UK person /year
Also, #HS2 will last much longer than 1.2 million electric vehicles.
Plus there's ecological impacts of lithium mining for EV batteries. Though building rail takes more concrete?Still :#RailNotRoad

@PNASNews @Cambridge_Uni Thank you to the caterers who generously shared time&data. This would have been impossible without you.
Huge thanks to my fantastic co-authors: Andrew Balmford, @MarteauTM, @csandbrook& Mark Pilling.
Thank you to @CamZoology, @cambridge_uccri, & @NERCscience for my funding /2
@PNASNews @Cambridge_Uni @MarteauTM @csandbrook @CamZoology @cambridge_uccri @NERCscience We collected data across 12 in 2017 months comprising >94,000 meal selections, >90% of which we could link to anonymised individual diners.

It’s very unusual to have individual-level data in behavioural field studies this size. /3 Image
