Tissue Engineering can be defined this way (Wikipedia):
Tissue engineering is the use of a combination of cells, engineering and materials methods, and suitable biochemical and physio-chemical factors to improve or replace biological functions. While it was once categorized as a sub-field of bio materials, having grown in scope and importance it can be considered as a field in its own right.
Tissue Engineering and Regenerative Medicine International Society is an international learned society. Its goal is the worldwide advancement of both the science and technology of tissue engineering and regenerative medicine. Thematic groups include: Developmental biology; Scaffolds and matrix biomaterials; Bioprinting; Biofabrication; Bioreactors; Bioprocessing; Inflammation and immunity; Imaging; Cell sourcing and manipulation; Pre-clinical protocols; Clinical trials; and Infrastructure – regulatory, health economics, ethics.

This stuff is quite expensive now (2012), but with time it will become common and used by the general public. Amaze yourself with the following videos: Bioprinting (News), Bioprinting (Future), Lab Grown Lung, Skin Gun, Synthetic Biology.
Plus, some characteristics could be modified to even be more eco-friendly!
Possibilities are unlimited…
1. No passwords: You will never need a password again because of what IBM calls “multi-factor biometrics.” Smart systems will be able to use retina scans and other personal information in real-time to make sure whenever someone is attempting to access your information, it matches your unique biometric profile. To be trusted, such systems should enable you to opt in or out of whatever information you choose to provide. Your biological makeup is the key to your individual identity, and soon, it will become the key to safeguarding it. You will no longer need to create, track or remember multiple passwords for various log-ins. Imagine you will be able to walk up to an ATM machine to securely withdraw money by simply speaking your name or looking into a tiny sensor that can recognize the unique patterns in the retina of your eye, IBM said.
2. Mind-reading: IBM scientists are among those researching how to link your brain to your devices. If you just need to think about calling someone, it happens. Or you can control the cursor on a computer screen just by thinking about where you want to move it. Scientists in the field of bioinformatics have designed headsets with advanced sensors to read electrical brain activity that can recognize facial expressions, excitement and concentration levels, and people’s thoughts without them physically taking any actions. Within five years, we will begin to see early applicationsof this technology in the gaming and entertainment industry. Furthermore, doctors could use the technology to test brain patterns, possibly even assist in rehabilitation from strokes and to help in understanding brain disorders, such as autism, IBM stated.
3. Digital divide? In five years, the gap between information haves and have-nots will narrow considerably due to advances in mobile technology. There are 7 billion people inhabiting the world today. In five years there will be 5.6 billion mobile devices sold — which means 80% of the current global population would each have a mobile device.
4. No more junk? In five years, unsolicited advertisements may feel so personalized and relevant it may seem spam is dead and spam filters will be so precise you’ll never be bothered by unwanted sales pitches again, IBM said. IBM pointed out that it is developing technology that uses real-time analytics to make sense and integrate data from across all the facets of your life such as your social networks and online preferences to recommend information that is only useful to you.
5. Power. Advances in renewable energy technology will allow individuals to collect al sorts of kinetic energy — walking, bicycling — which now goes to waste, and use it to help power our homes, offices and cities. Imagine attaching small devices to the spokes on your bicycle wheels that recharge batteries as you pedal along. You will have the satisfaction of not only getting to where you want to go, but at the same time powering some of the lights in your home, IBM said.
Cars will be different in the future. How different? A lot!
Imagine the revolution in smartphones from 1992 to 2012. Now imagine cars with augmented reality. Now see the latest Toyota video on the topic:

Other possibility to accommodate more people is Seasteading.
The basic idea is the same: to be self-sufficient and to aim for the skies to avoid space constraints. But what this vision adds is that one can be independent from an old state and live with new rules and lower taxes.
The “floating” cities would then be built on off-shore platforms (similar to the oil ones). The city would then include hospital facilities, schools, universities, utilities, … and even a legislative body!
Here is why it ought to exist floating cities, according to their own words:
Why The World Needs Seasteading
The vision of seasteading is an urgent one. We can already see that existing political systems are straining to cope with the realities of the 21st century. We need to create the next generation of governance: banking systems to better handle the inevitable financial crises, medical regulations that protect people without retarding innovation, and democracies that ensure our representatives truly represent us.
Seasteaders believe that government shouldn’t be like the cell phone carrier industry, with few choices and high customer-lock-in. Instead, we envision a vibrant startup sector for government, with many small groups experimenting with innovative ideas as they compete to serve their citizens’ needs better.
Currently, it is very difficult to experiment with alternative social systems on a small scale; countries are so enormous that it is hard for an individual to make much difference. The world needs a place where those who wish to experiment with building new societies can go to test out their ideas. All land is already claimed — which makes the oceans humanity’s next frontier.
Planet Earth is now home to 7B – 7.000.000.000 – individuals.
The media spends too much time scaring people about it, while some entrepreneurs are already thinking of how they can profit from this growth and getting ready to support 7T – 7.000.000.000.000 – and not 7B (I can only wonder what a person would think of 7B when the 7M mark was passed…).
Well, those entrepreneurs are considering… Vertical Farming.
Vertical farming is a way to produce food inside mega-cities like highly-populated Tokyo, highly-poluted Mexico City or cold Moscow, making those cities food independent, at least for some categories of products, while occupying only a small fraction of the city ground.
This will answer the problem of population growth till space is cheaply available, the urbanization challenge, and avoid food wars in the next century. It will have also collateral benefits, like no weather-related crop failures, reduction of herbicides and pesticides used, water-reutilization, fossil fuel use reduction, fresher food to cities, farming in previously inhospitable places, and of course better employment than traditional farming with better wages and work conditions. This is how cities will look like in not a very far future.
