Our world in 2100???

Food:
Vegatables will grow in a sealed enviroment. There is no sun light in this environment, no rain, no oxygen. Every aspect of  the growth proces is regulated by computer: sumlight (led), water, oxygen, fertilizer etc. All the charistics of the food are "under control": tast, colour etc. And everything on demand. A bit more tasty of sweet? Just ask. And,,,no insectisides, no poison etc. necessary. The food will grow in layers, one above the other. At the end: NO FAMINE in the world anymore!!!!

In 2100 it will not be necessary anymore to rear cows, chicken or pigs or in general animals  for meat to eat. We take little cells, so called stem cells from an animal and we make “cultured meat”. This meat is exactly the same as “old fashioned meat”. It is safe, the taste is the same, and the properties and quality can be guaranteed by using computers for the process.

So, no food for animals needed anymore. The place we needed for this animal food now can be used for recreation. Great idea. And MacDonald’s? Well: cultured hamburger, no problem!!!

Energy:
No CO2 anymore!Nuclear energy will be used because we have solved the problem of nuclear waste. All the nuclear waste will be re-used for 100%!!!

Traffic:
of course: electric cars, using computers for driving without help of the driver, not using fossile gas anymore, no CO2. The long distance traffic is in tunnels, the goods transportation too.

Health?
In our body's there are some nano chips that controle the health situation of our body and these chips give signals to our home computer. If something is wrong we can order the computer to analyze the situation and then a message is given to the chemist's. Then a drone brings us the asked medicine.
In case that we have to go to the hospital the damaged part of the body will be replaced by a new one, made out of our own stem cells.....
