Goal 11 - Sustainable cities and communities

Cities are growing rapidly because many people are moving there. This change demands an ecologically, economically and socially sustainable way of life. We must rethink things the way we live and come up with new ideas. That’s exciting, and the possibilities are endless because the "new" city of the future does not yet exist.

For our own well-being as well as that of our cities and nature, it is important that we plant trees and plants in the cities. Among other things, they help create pleasant environments, take care of impurities and lower the temperature.

The challenge – Build more homes!

In order for the plants to survive, their pollen must be spread to other flowers. This is called pollination. Insects such as bees, butterflies and bumblebees are important pollinators. These insects need somewhere to live, lay their eggs and hibernate, but in our tidy gardens and parks it can be difficult for the insects to find a good home. You can build your own insect hotels!

PET-bottle hotel:

Fill containers, for example a cut-off PET bottle, a flower pot or the like with different kinds of natural materials. You can fill one with leaves, one with rolled corrugated cardboard, etc. It is important that the container have a bottom, so that the wind cannot blow straight through. To keep the birds from being able to eat the insects, fasten a piece of fine mesh netting or a piece of chicken wire over the mouth of the container.

Wood hotel:

Ask an adult to drill holes in a piece of wood. The holes can vary between 2 to 8 mm in diameter and should be at least 5–6 cm deep (don’t drill the holes all the way through the piece of wood; if you do, the wind will blow straight through it).

Place or hang your hotels outdoors in a warm but not too sunny spot and wait for your guests to check in.
