Can Tech Help Sustain Our Planet? - BBC Click

[@tams805]

Congratulations on making it to 1,000 episodes! Looking forward to it!

[@RonakDhakan]

Like every other inaccurate video, BBC shows steam coming out of cooling towers when talking about CO2 emissions.

[@notrocketscience96]

As odd as it sounds, water vapour/steam is actually the biggest greenhouse gas. Although it doesn't actively break down the ozone layer, it absorbs vast amounts of IR radiation (heat from the sun) and keeps the temperature rising. CO2 is just breaking down the little protection we have left. Powerful combo, I guess that's why they had it in the video.

[@garrykid]

You also missed the stacks next to Cooling towers which are the source of various green house emissions from Thermal Power Plant.

[@egmontmartinez2861]

Congratulations!!! Excelent show!!

[@KBTECHWAQAAS]

[@tristanpatterson3843]

Yeah lol, Isn't that just steam?

[@Dowlphin]

Weeelll, what you are seeing there is a VERY potent agent of the greenhouse effect. 😉

[@gopinathms2012]

Nuclear energy is one of the most underrated energy producers, only the radiation things cause fear but modernizing some old rules and maintaining the plants will be a crazy efficient and cleaner energy source

[@Apodeipnon]

Coal/gas power plants also use cooling towers! Look, there are also normal chimneys there. That could very well have been a fossil fuel plant.

[@krrk6337]

[@zeph6439]

Thank you. We still need to plant as many trees as possible - select native or endemic, indigenous plant species. We also need to remove all exotic invader plant species.

[@AsylumCom]

I LOVE THIS SHOW. CONGRATULATIONS

[@cb14011970]

Why not start by re-planting trees and stop cutting down forests and destroying local natural ecosystems which include vegetable material which naturally soak up the harmful greenhouse gases, the urban landscape is a great place to greenscape. Semi-arid areas could also do with re-planting.

[@correctionguy7632]

that alone wont be enough, not to mention that trees takes decades to fully grow to then store carbon. Not saying we shouldn't do it, but claiming theres an all rounder simple solution is delusional and there needs to be work on all fronts with immediate effect outside of these halfassed responses.

[@robinbinder8658]

mature forests are at dynamic equlibrium you fool... cutting the trees when they passed peak growth and replanting new seedlings for them is better actually, then you use to wood to build houses.... also you need to "clean" forests for max growth efficiency and storm hardiness, you need to take trees down...

[@rsamblee]

Forests are temporary carbon sinks not a permanent one! If forest catches fire, all the carbon stored for decades would be released in seconds! If trees decay because of flood, carbon is released back. That is what is happening now. Rain is random, so forests are not dependable sinks any more. Trees also take a long time to grow and absorb co2. A plant takes years to grow and start absorbing co2. Every year we are releasing 40 Billing tons of Co2. So, if you plant a tree today, by the time it start absorbing, we would have released 100 times that. Overall the plan should be rapid switch over to solar from fossil, absorb co2 artificially and naturally by reforestation. All these are trillion dollar investments. Young entrepreneurs should be motivated to make this into a business venture rather than a philanthropic effort.

[@kingpatwreckkk6194]

Many countries in the world have already started replanting decades ago. And ecologists argue that still this is not enough. Your comment is just as ignorant.

[@puddingfoot]

there are FAR more effective methods of climate control than carbon capture, which is horribly expensive

[@Dowlphin]

The solution is not climate control. Control freaks are what destroys us. The solution is to take a chill pill. But who wants that? Too boring. And so people become what they fight, manifest what they allegedly oppose.

[@VideoSage]

It's so upsetting to see the guy at 15:00.... Let me rephrase that, it's so upsetting that we don't have a solution for people like the bloke at 15:00. Lab grown limbs, or synthetic ones, or... Something I can't even think of, a solution for him, and those like him, should exist in 2019!

[@timothyrarick6710]

Great show as always, very interesting reporting. However, in the talk of climate change and what we need to do, I never see much reporting on what is going on in South America, India, Russia, and China. Would it be possible to focus on the non-European or North American efforts to tackle this crisis? We're all in this boat together.

[@hglenn55]

Do a story on ships dumping their black water tanks before they arrive in port to lower cost. When they arrive in port they have to pay to have those tanks pumped. But they're not stupid. If they totally dump they know they will be fined so they dump a majority of it which means a lower rate they have to pay to the deposal company. Shipping is vital to the world but the way they go about it is worse than most other pollution aspects. Where do y'all think those floating plastis islands come from? Not most of us. When's the last time you threw something away in the ocean? I bet almost never.

we are all tech

[@truetech4158]

We should be rapidly installing forms of automation, if to overcome our industrial disease. We need to become unemployed, or if we dont, we end up returning to the factories and office desks to create yet more layers of carbon to the soupy mix you can see hovering over all the cities that disperses as it travels. We should be focusing on consumer goods that are designed to be reused in multiple ways, taking cues directly from the lego block. You have this phone you might be reading this on, and it doesnt all you to swap out the battery anymore. You can't simply replace a broken segment of it, because it's been designed to end up in the landfill as a entire item rather than only a broken segment of it. It's the industrial disease right there, and without any real afterlife as a backup plan, only a hollywood fake news version of one. It's time to wise up to the frauds our species has created.

[@jimmyporter8941]

It makes far more sense to plant real trees than "artificial trees". The scientist who prefers his technology says trees need more space. But that's fine. We've got lots of space. Take a look at Russia, the biggest country in the world, and yet the vast majority of it is completely uninhabited and mostly grassland. It could be forested. At the same time, we should be bringing trees back into urban environments, mixed in and amongst the buildings. The alternative of filling these spaces with "artificial trees" is both far more expensive, and far less desirable.

[@jimmyporter8941]

@@rsamblee Temporary eh? What do you think the carbon that is trapped in coal and oil was when it was first captured? That's right, biological material such as trees. Fossil fuels are prehistoric forests. The carbon captured in trees can be released quickly, or slowly. It all depends on conditions. And it's usually a bit of both. This isn't theoretical. Planting trees is the number one way of capturing carbon in use today.

Carbon capture... rather like the sea does?? CO2 is not a greenhouse gas it is the issue, it is the foundation of life, crop increase etc. The real problem is pollution, plastics, etc. The problem with stopping pollution is that the corporatocracy cannot make money from its waste as easily as charging us all carbon tax..

[@ahaveland]

Yawn. A carbon tax is a tax _for_ the people, not a tax _on_ the people - you get the money back and the polluters pay. It is a Republican idea. And yes CO₂ is a greenhouse gas and it will destroy civilization in less than a century if not put back where it came from ASAP.

[@thelastorca]

Pls make it into carbon fiber. Seems to be too expensive.

[@jeremytravis360]

The real issue is that humans require energy and that produces heat. Humans demand for heat is the real issue. I don't understand why they don't use the same principals they use to produce carbon particles for Co2. Is it not a case of making bucky balls from carbon dioxide.

[@ronaldgarrison8478]

Too bad this program only devotes seven minutes to the CO2 removal story. That's just enough time to get people completely confused. Lackner is right that artificial trees are the way to go. The required land area is not a problem, as it is for real trees. But when you listen to Lackner, he's much too favorable to the idea of continuing to use fossil fuels. In that sense, his idea is a bit dangerous. We need to convert to renewables first. Artificial trees are going to need a lot of cheap energy, and only renewables can provide that in the time frame required. So while artificial trees are the way to go, now is not the time to focus on them. The ideal thing would be to have a place with a lot of industrial activity producing a lot of waste heat that can drive the recovery of CO2 from the ATs, and a good place to pump the CO2 deep underground. Iceland might be a really good site for that; they already smelt a lot of aluminum there with their cheap electricity. And they have geological faults where the CO2 could be pumped deep into the ground. No way are we going to drink enough beer to use all that CO2! (Besides, we would just belch it all out again.)

[@DeusExRequiem]

Technically, global warming is really bad for humans and our cities, not so much for nature itself as everything will just adapt over time to the changes. If anything the increased CO2 in the air will, in the long term, increase the resources available for trees. Until now, the worlds deserts and grasslands have been pushing back the forests, which at one point covered the planet. Most of the CO2 was locked away, never to be accessed by nature again, but we're reversing this process... at our own long-term expense. This means a world war will happen once there's food shortages or something, war has always been over scarcity. Lets hope we get asteroid mining working soon, maybe we can set up farmland in space and just drop food down to earth?
