Even really green cities in Germany with a lot or parks, wood and green are not really nature and people friendly. Especially for kids and old people, they are even dangerous. And it is really not so complicated to change this – just consider the following simple ideas:
1. City centre cars free
2. Make green grass lanes for walking on the streets and plant some flowers and trees at every street.
3. Use the roofs of the buildings. These can be used for gardens and food growing and for student rooms. And of course for collecting rain water and producing electricity from the sun, the wind and the difference of the temperature between the building and the air.
4. Put a beehive in every garden and seed a lot of colourful flowers.
5. Use the walls of the buildings to create hanging gardens and produce our own food.
If we just let our creativity fly, we can create even better ideas and change our cities completely.
