The sad thing is Attenborough has lived to see the destruction of nature he loved so much. His constant warnings have gone mostly unheard. In some ways I think excellent nature programming like his own Nature is doing a disservice by making it seem like there's lots of wild nature left.

I wish humans would come together to re-wild more of the earth. Restoring wild nature and cutting emissions is the only way to really restore natural ecosystems. We're nowhere close to doing that.

I would strongly push back on that. In most developed countries, natural wilderness is at its highest rate in hundreds of years. China's turning around the world with solar panels, all that. I wouldn't call the current state of things backsliding at all.

  • Even granting your numbers, you're measuring the wrong thing. Wilderness acreage and emissions trends are not ecosystem health.

    Citing a wilderness figure for developed countries is misleading. Most of it is ecologically vacant--second-growth and tree plantations sans apex predators, large herbivores, intact soil biota, etc. Tree cover is not a functioning ecosystem. Developed countries have exported their ecological destruction: the beef, soy, palm oil, and minerals driving habitat loss in the tropics get consumed in the same places where the domestic "wilderness" figures look great.

    The Living Planet Index (actual wild vertebrate populations) is down 73% on average since 1970. North American bird populations are down ~3 billion over the same period. Terrestrial insect biomass shows steep decline in studied regions. None of that shows up in "how much undeveloped land exists" or "how many solar panels got installed."

    China's solar buildout is great news for climate, but climate is one driver among several. Habitat fragmentation, pollution, and overfishing don't get solved by the energy transition. You can decarbonize the entire grid and still preside over a mass extinction.

  • And in developing countries too. People may not realize that when there's no industrialization, people still need fuel. So they cut down tree that they could walk to. Just look at the pictures missionaries and travelers took in China a hundred years ago. Wherever there were people, there were only barren land. Heck, it was like that even in the early 80s in some places.

  • You do know that in china while renewables are 30-40% of installed capacity(how many GWh they can theoretically produce), they are a smaller portion of generated capacity because if inefficiency of grid, intermittency if sun and wind. They are a smaller ~9-10% of Total Energy consumed (which is much bigger pie including for e.g. gas cars, jet fuel, diesel etc), right?

    They may be able to distribute all solar panels and wind turbines worldwide; in the end that is just tiny-potatoes good because those markets are not that big. But when it comes to getting to energy independence they are using an "all of the above" strategy to get there. Planetary catastrophy can take a back seat to socio-economic unrest due to less/no money and opportunities for people.

  • Too little too late. China's coal emissions declined last year by a whooping 0.3%... after decades of increasing. We should be already reducing emissions, not flattening the curve

Well to make matters worse remember we're about to add another ~2 billion humans (Quark DS9 voice) peaking at around 10 in the 2080s.

Most of the growth will be in Africa, not exactly the most lawful place in the world so it looks kind of bleak for the environment and animals there.

Those 2 billion will all want a nice home and a smartphone, computer, TV, car etc…

It's not looking great, not even if we got nuclear fusion reactors figured out tomorrow.

  • Hopefully by 2080 the value of solar plus storage (or something even better) makes things like coal uneconomic.

Every Nature documentary that ends with David Attenborough saying "there is still time to revert this destruction of natural habitat" makes me want to turn of the TV. I understand David's motivation (instill some catalyst for change) but I am with that other David - David Suzuki.

As per David Suzuki: it is shit, it will get shittier, responsible people should act accordingly [0]: <<"The science has said, ‘We have passed a tipping point, we cannot go back,'" Suzuki said. Survival in a warming world, he says, will increasingly depend on the resilience of local communities — and preparation must start now.>>

Looking at EU, the problem do not seem that his warning has not been heard. People see how thing has gotten worse and have heard the warning. The problem is that people can't agree on what to do next. Just looking at the energy discussion in EU, half of those want to use natural gas in Peaker Plants, and the other want to use nuclear, and the result was that both strategy got the EU stamp of green with neither side agreeing with each other. By both sides opposing each other strategy, the result is that very little change happen at all.

A similar situation exist with hydro power. We know that it is causing major extinction of species that depend on migration, with major harm to the ecosystem, and yet no one want to give it up despite being fully aware of the harm. Removing hydro do not fit any of existing strategies and so the current situation, as unreasonable it is, continues unchanged.

I have also seen similar issues here on HN when people discuss emission per capita vs absolute emissions. A large portion of people who heard the warning and are aware of the effect of global warming, would still argue that reducing emissions where emissions are being created is unfair if emissions per capita is relative lower compared to other places. The two camps created from this has opposing strategies, even if both camps agree with the current situation.

Ultimately, it speaks to people's lifestyle choices. In the US people are used to a particular standard of living: driving big cars and eating big steaks. If you tell people you can't have those things, they will have a visceral reaction. Politicians caught wind of this and turned it into a divisive left vs right debate. Im oversimplifying, but at the core its an incentives problem: Why should I tighten my belt today for some future payoff I may not even be around to see?

  • It's more like - why should I tighten my belt today when the celebrities, politicians and corporations making a big fuss about climate change are still flying around in private jets, buying up coastal property, eating steaks and are responsible for the vast majority of greenhouse gas emissions?

    • What kind of argument even is that? What's next - "why should I care about hurting you when there's so many sociopaths out there that clearly don't"?

fwiw a lot of his programming has for decades included explicit conservation messaging and warnings about climate change, disappearing habitats, etc. It's an old strategy (and one he helped invent) of making people care about the thing they're seeing before telling them it's being destroyed.

David Attenborough saw more clearly than most what was being lost. But even he stopped short of fully applying that logic to animals themselves.

Rewilding at scale, deep emissions cuts, and a serious move away from animal agriculture are the same project.

  • He did mention in one of the planet earth 2/3 series how so much of the land is used for farmed animals. And, for the sake of completeness of argument, for restoring what was lost, the challenge is how to raise the standard of living fast enough for people so they give a damn about anything apart from ourselves was THE challenge to combat climate change and global ecological disaster. He specifically mentioned e.g. educating girls and making older-aged societies more propsperous. Prosperous people can make better choices about farmed animals as food.

  • Modern agriculture, both animal and non-animal versions, are bad for the environment. Artificial fertilizers, replacing forests with farm land, and drainage of wet lands are all heavily contributing to emissions and water pollution, destroying local ecosystems as well as warming the planet. Artificial fertilizers is particular bad since its production uses fossil fuels, has large amount of accidental green house emissions, and causes eutrofiering to the point of areas like the baltic sea becoming basically dead from loss of oxygen. Runoff from farms are also now the primary cause of ecosystem collapse in fresh water lakes.

Population 1926: ~2 billion

Population 2026: ~8.3 billion

Can't escape this and its consequences on the environment.

'Cutting emissions'. Trouble is that if folk are convinced this is so negative they'd do something about it - and they do not. Conclusion?

The renewables revolution has been accompanied by a steady increase in emissions. For emissions read carbon dioxide (no argument from anyone about toxic gases) which is a carbon source for plant growth and as we know, is pumped into greenhouses to increase production. Satellite pictures confirm greening of the Earth in many areas.

This does not have to be a counter argument but the emission story would be more convincing to a lot of people if other factors like this (and the difficult question of just how do you decrease energy use without impoverishing people?) were discussed in the public forum in a balanced way as with dissenting views from those distinguished scientists evidently holed up on luxury yachts financed by the oil industry. 'I think you are wrong because ...' or 'you have a point in that respect but ... '. In a nutshell let's get the discussion onto what used to be called 'an adult level'.

> I wish humans would come together to re-wild more of the earth. Restoring wild nature and cutting emissions is the only way to really restore natural ecosystems. We're nowhere close to doing that.

A big issue is cost and economic opportunity. For example, a lot of land in the SF Bay Area cannot be developed. This is great for the environment, but not so great for housing costs.

Long term, it’s likely worth it to save the environment, but let’s not ignore its immediate cost to everyone besides the upper class.

  • They’re not necessarily at odds. Manhattan has something like 75x the population density per mile. You could rewild 4/5 of the the SF Bay Area while also building 10x the housing stock under that development pattern. Single family homes are just an extremely expensive and ecologically destructive way to live. They require a ton of infrastructure per person.

    Unfortunately, I think that housing unaffordability is just a desired feature - people who live there don’t want to live near people who couldn’t afford to live there. It’s much more segregated than many other parts of the country I’ve lived in.

Sadly I don't think the outlook is very positive on that. I saw an article from McKinsey about the Himalayan country of Bhutan which has famously put restrictions in place to keep the country heavily forested. Good for nature, good for preserving culture, not so great for capitalism.

The article I saw basically outlined in more detail what I said above and then followed it with: "....but what if that forest could be made productive?" It's rare that I want to reach through the screen and choke somebody but they got me that day.

The cult of Line Go Up will continue to win. They will destroy what we have and then sell us the solution to the mess they created. This will be coupled with a morality tale around individual hard work and personal accountability.

  • The Himalayan country of Bhutan has seen 6% of its population emigrate since 2020. People enjoy the preservation of nature, but they also enjoy having more and better stuff, and a healthy society can't just tell people the second impulse is wrong and they need to give it up.

    • "People" and their "wants" or "enjoyments" are manufactured by culture (which is in turn now dominated by corporate propaganda). They are not fixed by nature. Any examination of the range of 'wants' in human history will inevitably conclude that, beyond a few corporeal basics, they are endlessly plastic. This is hard to see from the centres of Empire (especially highly mediated ones) where local and highly propagandised 'desires' are seen as 'natural'.

      Agricultural societies are machines for creating large numbers of humans. In any democracy (or sufficiently responsive government) the kinds of persons that are created is a powerful determinant of what subsequently happens. Corporations choose to make consumer-humans. Many other types have existed, so ipso facto are possible.

  • The "cult of line go up" is why we aren't living in caves and eating each other. Come on, we can criticize the deleterious aspects of modern society without disparaging the idea of growth itself.

    • 1. At a certain point, the idea of growth must be criticized. Unless, of course, you think infinite growth is possible.

      2. Claiming the modern capitalism’s “cult of line go up” has anything to do with humans leaving caves is a stretch at best and intellectually dishonest at worst. Humans left caves out of a desire to create better lives. Stable shelter, better quality and variety food, tools to make life easier, clothing to protect us, etc. Plus probably some human desire for exploration. None of that is driving capitalists who insist “line must go up”.

      We have more than enough to go around. We cannot grow infinitely. Greed is holding us back from caring for our entire human population.

57 companies are responsible for 80% of greenhouse gas emissions. I'm very tired of people trying to tell others that not eating meat or driving a vehicle with an internal combustion engine is the key to solving the problem, because it's not and never has been.

  • This is extremely reductive. Noting that oil, gas, and cement companies are responsible for pollution is ignoring that oil, gas, and cement are inputs to everything we consume and the infrastructure used to transport goods. Exxon Mobil isn’t extracting oil and burning it for no reason, it gets refined into gasoline, diesel, jet fuel, plastics, pharmaceuticals, etc. Cement is used in concrete which is what infrastructure is made of, along with steel. Everyone uses infrastructure, either directly or indirectly. Everything you buy was transported on a truck, and possibly a plane or a ship. The supply chains for the components of products you consume, and so on. It’s impossible to avoid if you want to maintain the current global population. We could stop using oil and cement, but there would be mass starvation and our current infrastructure would degrade and crumble over time.

    • Right - so how is me not eating meat or not driving an ICE vehicle going to help change the situation? The people with the capital to actually change things seem to be more interested in mongering fear while continuing to profit off of their ecosystem-destroying industries, than trying to come up with effective solutions to the problem.
