Aeroplanes have become bigger and faster but their impact on the climate has also increased.

Jet engines burn kerosene which releases carbon dioxide – one of the main greenhouse gases causing climate change.

So, could hydrogen powered planes be the solution?

  1. How many airmiles has Attenborough and his 50 strong team of monkey photographers got under their belt?

  2. If you're a celeb
    Royal
    Politician
    Or other elite
    Its perfectly fine

    If you're one of the masses though , make sure to separate your recycling and drink through paper straws

    And choose vegan burgers you cow hater 😡

  3. BUDDHA-

    So I have heard. At one time the Buddha was wandering in the land of the Kosalans together with a large Saṅgha of mendicants when he arrived at a village of the Kosalan brahmins named Bamboo Gate. The brahmins and householders of Bamboo Gate heard:

    “It seems the ascetic Gotama—a Sakyan, gone forth from a Sakyan family—has arrived at Bamboo Gate, together with a large Saṅgha of mendicants. He has this good reputation: ‘That Blessed One is perfected, a fully awakened Buddha, accomplished in knowledge and conduct, holy, knower of the world, supreme guide for those who wish to train, teacher of gods and humans, awakened, blessed.’ He has realized with his own insight this world—with its gods, Māras and Brahmās, this population with its ascetics and brahmins, gods and humans—and he makes it known to others. He teaches Dhamma that’s good in the beginning, good in the middle, and good in the end, meaningful and well-phrased. And he reveals a spiritual practice that’s entirely full and pure. It’s good to see such perfected ones.”

    Then the brahmins and householders of Bamboo Gate went up to the Buddha. Before sitting down to one side, some bowed, some exchanged greetings and polite conversation, some held up their joined palms toward the Buddha, some announced their name and clan, while some kept silent. Seated to one side they said to the Buddha:

    “Mister Gotama, these are our wishes, desires, and hopes. We wish to live at home with our children; to use sandalwood imported from Kāsi; to wear garlands, perfumes, and makeup; and to accept gold and money. And when our body breaks up, after death, we wish to be reborn in a good place, a heavenly realm. Given that we have such wishes, may the Buddha teach us the Dhamma so that we may achieve them.”

    “Householders, I will teach you an explanation of the Dhamma that applies to oneself. Listen and apply your mind well, I will speak.”

    “Yes, sir,” they replied. The Buddha said this:

    “And what is the explanation of the Dhamma that applies to oneself?

    It’s when a noble disciple reflects: ‘I want to live and don’t want to die; I want to be happy and recoil from pain. Since this is so, if someone were to take my life, I wouldn’t like that. But others also want to live and don’t want to die; they want to be happy and recoil from pain. So if I were to take the life of someone else, they wouldn’t like that either. The thing that is disliked by me is also disliked by others. Since I dislike this thing, how can I inflict it on someone else?’ Reflecting in this way, they give up killing living creatures themselves. And they encourage others to give up killing living creatures, praising the giving up of killing living creatures. So their bodily behavior is purified in three points.

    Furthermore, a noble disciple reflects: ‘If someone were to steal from me, I wouldn’t like that. But if I were to steal from someone else, they wouldn’t like that either. The thing that is disliked by me is also disliked by others. Since I dislike this thing, how can I inflict it on someone else?’ Reflecting in this way, they give up stealing themselves. And they encourage others to give up stealing, praising the giving up of stealing. So their bodily behavior is purified in three points.

    Furthermore, a noble disciple reflects: ‘If someone were to have sexual relations with my wives, I wouldn’t like it. But if I were to have sexual relations with someone else’s wives, he wouldn’t like that either. The thing that is disliked by me is also disliked by others. Since I dislike this thing, how can I inflict it on others?’ Reflecting in this way, they give up sexual misconduct themselves. And they encourage others to give up sexual misconduct, praising the giving up of sexual misconduct. So their bodily behavior is purified in three points.
    Furthermore, a noble disciple reflects: ‘If someone were to distort my meaning by lying, I wouldn’t like it. But if I were to distort someone else’s meaning by lying, they wouldn’t like it either. The thing that is disliked by me is also disliked by someone else. Since I dislike this thing, how can I inflict it on others?’ Reflecting in this way, they give up lying themselves. And they encourage others to give up lying, praising the giving up of lying. So their verbal behavior is purified in three points.

    Furthermore, a noble disciple reflects: ‘If someone were to break me up from my friends by divisive speech, I wouldn’t like it. But if I were to break someone else from their friends by divisive speech, they wouldn’t like it either. …’ So their verbal behavior is purified in three points.

    Furthermore, a noble disciple reflects: ‘If someone were to attack me with harsh speech, I wouldn’t like it. But if I were to attack someone else with harsh speech, they wouldn’t like it either. …’ So their verbal behavior is purified in three points.

    Furthermore, a noble disciple reflects: ‘If someone were to annoy me by talking silliness and nonsense, I wouldn’t like it. But if I were to annoy someone else by talking silliness and nonsense, they wouldn’t like it either.’ The thing that is disliked by me is also disliked by another. Since I dislike this thing, how can I inflict it on another?’ Reflecting in this way, they give up talking nonsense themselves. And they encourage others to give up talking nonsense, praising the giving up of talking nonsense. So their verbal behavior is purified in three points.

    And they have experiential confidence in the Buddha … the teaching … the Saṅgha … And they have the ethical conduct loved by the noble ones … leading to immersion. When a noble disciple has these seven good qualities and these four desirable states they may, if they wish, declare of themselves: ‘I’ve finished with rebirth in hell, the animal realm, and the ghost realm. I’ve finished with all places of loss, bad places, the underworld. I am a stream-enterer! I’m not liable to be reborn in the underworld, and am bound for awakening.’”

    When he had spoken, the brahmins and householders of Bamboo Gate said to the Buddha, “Excellent, Mister Gotama! … We go for refuge to Mister Gotama, to the teaching, and to the mendicant Saṅgha. From this day forth, may Mister Gotama remember us as lay followers who have gone for refuge for life.”

  4. Whats the carbon footprint of RAF, USAF and all the other airforces? What about private jets etc?

  5. in the meantime it is a highly taxable activity

  6. It is hope, an alternative to fossil fuels, indeed it will be less emissions a cleaner planet 🌏

  7. Nah..just use fusion innit!

  8. Dirigibles! Dirigibles!

  9. I think it will take a generation or more before we see commercial hydrogen aeroplanes & I cannot see it will work for Emirates alike

  10. all part of the plan so only the rich and famous are allowed to fly the rest of the public will not be allowed to help the planet its called hypocrisy everytime they fly thousands of miles on private jets to a climate conference to pass laws so the public cant fly

  11. Back to the Hindenburg technology again – Oh wait didn’t it blow up?

  12. No. Next question.

  13. Of course it will. If humanity lives long enough, everything will be sustainable. Air flight will be easy in terms of many others..

  14. The BBC should stop sending thousands of journalists and their crews to the far flung corners of the globe for a picture of a Panda. They themselves must be largely responsible for the state of the planet, them and that Attenborough geezer.

  15. The elite want to stop us from enjoying a international holiday while they fly around in their private jets with 3 people in them! Fuck off!

  16. Nothing will ever be sustainable for ever. Get over it. One day the sun will run out of energy, not even the sun is sustainable.

  17. Dunno, ask the billionaires who want to ban people flying in their hundreds, while they sit alone on a jet.

  18. Solar electric blimps

  19. I see the world and this comment board is filled with FUD'sters… No wonder nothing ever gets better…

  20. The travel industry is coming to an end, and flying will only be available to the super rich. That is the plan of UN Agenda 21.

  21. The 70,000 who flew to COP28 in Dubai say, “Yes”, but only for them.

  22. The climate religion deceivers use private jets to go from one rally to another – total hypocrisy on their part. 🤑🤑🤑

  23. the real question is will making babies ever be sustainable. the answer is no, so who cares about other less significant ideas

  24. Hydrogen is a terrible fuel from an energy-density and price perspective. To be fair, this was kind of acknowledged in the video but nobody should be holding their breath right now while waiting for this to happen. Good old fossil fuel will be the airline industry's only option for at least another decade or two.

  25. Overpopulation is not sustainable. Everything else is irrelevant. And stop with your climate bullshit

  26. UAPs, Tik tacs, Suaucers….camon guys🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸💪🏾👽‼️👽🌌 GET REAL

  27. Nothing wrong to dream bigger & faster, when engineering is all about turning a theory into reality.

    But if you really want to travel one country to the next, invest in trains. Planes will always use more energy than trains.

  28. bbc got satisfied by importinf gold looted from colonies in ships so how new flying technology will be invented?

  29. No ! Energy wise far to costly. Rail is still quite efficient.

  30. Typical having someone complaining about the emissions involved in constructing the technology, without actually challenging that and asking how many emissions are used to construct conventional aircraft.

    Also emissions to construct the technology will be coming down. Electric mining trucks are starting to be rolled out, the transportation of minerals that have just been mined would normally be trains which can be electrified as well as ships and the shipping industry has it's own plans for going zero carbon. Then there are smelting works to process the metal and hydrogen power smelting works are coming on line with one currently already fully operational in Sweden, and then there other transportation emissions where trucks are already going electric as well as factories relying on the power grid which is going more and more green as the years go on.

    So the emissions for constructing the aircraft will be involving less and less CO2 as different parts of different sectors have their own advancements, until in the distant future constructing the aircraft will have zero CO2 emissions.

  31. I will refuse to stop using whichever means of transport are cheaper and more conveniente for as long as we have hypocrites like Taylor Swift, pontificating about sustainability while taking more 20 minutes flights in a year than most people will take in their entire lives . . . with her two private jets.

  32. airplane transport is ridiculously cheap and all the damage it causes is not factored into the price. this needs to change globally. carbon emissions (and certainly the more harmful emissions like methane and ozone) need to get factored into the price of things. people need to feel the damage it causes – in their wallet. then suddenly, all these fairy tale dreams of clean transport become true. we have the tech, we just have to apply it properly

  33. Hydrogen combustion?

  34. Planet Earth will not die!! Only ecological hypochondriac alarmist believe that the planet will die!!

  35. The biggest generator of greenhouse gasses is primarily due to human consumption of resources. The root solution to a sustainable planet is a human population small enough to achieve this. There are too many people and it's about time we discussed this more instead of all this sustainable BS like EV's that serve no purpose other than as a short-term Band-Aid to a long-term problem.

  36. OT:

    Benny Hill considered funnier than Monty Python by two TV stations –WOR and WLVI!

  37. 編劇有沒有去<榮升刻印店>問鳳鳴高圓印章前一手的故事??2013-08-12深夜下毒暗殺我剛好是鬼月七夕情人節欸!!!編劇們沒問看準不準??
