Cities all over the world should be doing everything they can to discourage car ownership. High quality Public transport and pedestrian infrastructure are the only way for a city to meet the challenges of the 21st century.

[@KillianTattan]

What about designing cities around humans rather than cars? Mixed use buildings (shops, offices, apartments all in the same building) which means travel distances are shorter, as well as making energy use cheaper due to the density. Encouraging people to walk, take public transport, cycle rather than drive their expensive and inefficient cars.

[@kevinclack6679]

Fantastic video. However I disagree with the focus on composting. This is not a sustainable option in large-scale centralized applications. Centralized composting facilities will not last. They emit methane and nitrous oxide (36 and 298 times more potent than CO2, although not densely concentrated) and they still produce vast amounts of CO2 in this mostly aerobic process. A more sustainable option in the future is to first recover the carbon into a value-added product or biofuel, and then use the residuals as soil amendment (eg. Hydrothermal Liquefaction, Gasification, Pyrolysis, Anaerobic Digestion)

[@rajkishorebehera7489]

[@viewer-of-content]

@@rajkishorebehera7489 digestive reactors or modern landfills go through the process of composting while trapping methane for biofuel disposal. This both creates a green fuel and removes methane pollution which is 100 times more potent as a greenhouse gas as co2. The only issue is cost. It is much more green than traditional composting though and can still create compost. They just require tanks or tarps to capture gas

[@brentshuffler1234]

Kevin Clack, that is an interesting perspective. However, some countries and some large cities have done composting well on a large and commercially viable scale. E.g., from Barbados to Las Vegas, there are entrepreneurs who are collecting food and other organic waste from hospitals, from schools, from restaurants, from hotels, from supermarkets to avoid having these valuable resources treated as immediate garbage. Some items can be redirected to supply food-banks, the poor, the homeless. Other items can be composted and turned into soil for farmers and for households, and other outputs can go towards animal-feeds.

[@MrToritani]

I'm from Japan. Japan's population has been concentrated in metropolitan areas, especially in Tokyo. I suppose cities in Japan are relatively well-planed and well-organized but, in my opinion, Tokyo is facing the same problem as San Francisco. I feel that it's about time for companies to relocate their headquarters or branches from Tokyo to other areas in Japan, considering we no longer need to commute to offices thanks to the Internet technology. I assume that companies will do this in the near future because they've realized that there was no need to gather employees in one place during the pandemic. This trend could reduce traffic jams and then air pollutions in metropolitan areas. In addition, given that Japan is a country with many earthquakes, decentralization of business or government is quite important.

[@brentshuffler1234]

English Novice, thanks for those excellent observations. Decentralisation and diversification of food-supplies, of energy-supplies, of transportation, of work, of education, of public services, and of other important aspects of society and the economy, would do wonders for improving food-security, energy-security, reliability of supply-chains, reduction of risks from high dependence on metropolitan centres, and empowerment and inclusion of rural, remote, and other communities.

[@brentshuffler1234]

Iron Swan, these are excellent points. I would also add that dispersion of the population more evenly would decongest urban centres in multiple ways. People in cities are overpaying for everything, including food, clothing and transportation. The noise, the pollution, the growing unaffordability of cities to the bottom 90% of the income-distribution in most countries, the crowds, the traffic, and the risks from not growing one's own food, and/or not eating fresh foods from safe, organic, local sources, are contributing to sickness, to premature deaths, to overwork, to malstressors, to anxiety/depression, and to personal feelings of being in isolation, despite the presence of many other people. The disconnection of people from each other and from Nature contributes to a lack of peace, of joy, of health, and of spirituality.

[@Danny_6Handford]

Clever and smart people along with technology will help but, the idea and thinking that the economy always has to grow for humans to progress and to be able to survive may need to be reviewed and revised. Presently, if the economy is not growing, it is considered a problem and or a failure. Growing the economy is also thought to be the best way to help end poverty. If a growing economy could end poverty, the most developed and prosperous countries should not have any poverty. This type of thinking cannot continue uninterrupted on a finite planet with finite resources. There needs to be flexibility in the system for the economy to expand and contract and for a contraction to be considered normal and not a problem or a failure. For this type of thinking to work, there needs to be some new economic models developed along with some new types of money and financial systems based on economic sustainability! Not on economic growth!

[@WestOfEarth]

It's become clear you cannot build your way out of automobile congestion. Congestion comes down to human tolerance for inconvenience. If you increase capacity of highways, you'll get short term relief from congestion, but it will soon return to jamming up as people who had given up driving return to the automobile. The only way constructing more highways can work is if you construct super-by-pass corridors. Each suburb gets its own highway terminus, with no off ramps in between. Of course politically this doesn't work because the neighborhoods near the city limits get carved up and isolated, and the land given over to a super-by-pass provides zero economic benefits, unlike traditional off ramp / on ramp access which provides some economic stimulus.

[@justahamsterthatcodes]

Or, hear me out. Instead of running a highway from everywhere we should run public transit. Having a convenient bus route will reduce congestion by huge amounts. Right now in America you can't really live without cars, giving people other options to driving will really reduce car usage. Traffic there isn't a problem of not enough capacity it's a problem because cars are the only option.

[@WestOfEarth]

@@justahamsterthatcodes I'm not advocating for my idea. It's unworkable, and wasteful. I was only pointing out a way that building more roads would solve congestion.

[@Erin-rg3dw]

@@WestOfEarth Yes, but like you said, only briefly. I used to live near DC - we had highways go everywhere in every direction. Once a new road is built, it fills up. People take other roads (often residential or 2 lane) and then those roads have issues and turn into their own highways. Especially in these areas, with the population continuing to grow, the need for roads will only continue.

Interesting propositions - wouldn't it be even greener to deal with waste at source? Where there are homes that can equip themselves with specific bins for sorting waste products and a composting facility, these could be on hand. Where homes do not have the space - eg flats - there could be a communal waste site for recycling/composting. It would be more cost efficient than the full scale and probably more expensive processes. The waste generated is bought with the product - so the immediate disposal should be part of the buyers remit. They could remove packaging at the store and have a facility there for leaving it with the store if the store is not on board with recycling /net zero waste. The problem should be eliminated so that it isn't a problem, not nursed. We don't live in a world that is easily blanketed for some - the negative effects of living in a negative lifestyle affects the planet. L R

Yes, it may be greener and more efficient, but it ignores the reality of people. Getting a mass of individual people to change their behavior, to actually do the work themselves, is a huge hurdle.

[3] Therefore, I believe that we all can contribute to a better 21st century: [A] by having, on average, 1 child or none (optimal choice for the growing many in the world who are facing an uncertain labour-market, economic recessions/depressions, financial vulnerabilities, wars, recurring disasters, and such like) . . . and [B] by focusing on improving the life-conditions of those already born, instead of adding to their numbers.

Free energy made cities bigger but this is about to change with less and less energy available . Before the fossils fuel era so 2 centuries ago the size of the cities were limited by the food supply the surroundings can provide and transport using animals . With the end of the free energy people will have to leave cities and go to the countryside in order to produce themselves their food . Thought ‘ The economist ‘ will dig deeper than trying to explain how unsustainable system will evolve as it is a sustainable one . If you want to invest buy some land in the middle of nowhere and preferably in high latitudes certainly not real estate in cities.

Sustainability should not be the priority for the longterm health of a more urban society. Its an excuse for governments to expand their bureaucracy, taxes and power. What should be prioritize its the potential of individuality in realms of innovation and productivity. Most government's treat their citizen subjects as pawns towards an agenda that most of the time its utopic, unrealized or benefits a few well connected on the top. The rest of society feeds this monster of the state their time and resources for so called stability. Once we realized that we can achieve a more faster and happier growth through a system of less dependence on involuntarily altruism and coercion, our civilization will catapult towards the fourth industrial revolution. This will bring forth the most productive means and solve the greatest problems in our society. Cryptocurrencys, blockchains and smart contracts will lead the charge.

The only conclusion we can draw with certainty, is the following: NEVER LOOK AT USA examples! Look at European, Chinese examples of how to manage megacities. In terms of connectivity, promoting public infrastructure, waste management, energy handling, long term vision, they have the Americans beat!

I don't think we should be focusing on this problem. we should make housing, food, and energy human right. when we do this, and we can start in places of the modern world with high homelessness like california. my vision is not 1 big city more like 1 city made of smaller self-sustainable districts - which have their own power plant - nuclear fission later fusion. housing can be made more efficiently - small houses, which are easy to build, and repair. to do that we could nest shipping containers into the ground and build around several of those second layers to help protect against weather. we will not need pretty houses anyway since we will be moving to VR. today we have the technology to grow food more efficiently - laboratories can produce meat, and vertical farming can help make vegetables and fruit.

Similar the "Whim" concept, how about paying people not to own or use cars? For example, the denser the area, the more expensive it is to own a car. This could be done in ways like charging more for parking and gas, as well as making the taxes on them higher, encouraging people to take alternate ways. Right now, in many places, not owning a car just means you save money, but if you paid people not to have one or raised the cost, people would be less likely to use them and therefore discourage urban sprawl. Also, creating more mixed-use developments, like retail or office space downstairs and residential upstairs, instead of zoning for just one or the other.

[@davidturner4076]

Yes, let's push the poor out of car ownership!
