What is biodiversity?
Dandelion in the meadows, bromelia in the tropical rainforests, ladybugs in the city gardens, gorillas in the African mountain forests, bacteria in the hot springs of Iceland, golden eagles around the peaks of the Alpes, blue-green algae in a puddle, humans all over the world – This richness in nature is termed as biodiversity.
However, biodiversity includes more than just a variety of species. Also genetic diversity is a part of it. It is the genes that hold information about different forms of colour variations, i.e. of eye or coat colour, or the flavour of fruit. Finally, biodiversity also refers to the different natural habitats such as deserts, pastures, forests, rivers, oceans, lakes and cultivated landscapes.
The different species and habitats are connected and interwoven with their environment. This network is what makes the earth the unique, inhabited space as we know it.
What is the coloured house number?
The United Nations have proclaimed the UN-Decade on Biodiversity from 2011 to 2020.
The school network ESD (Education for Sustainable Development) Grevenbroich, Germany, intends to survey how many people already commit themselves to the goals of this UN-Decade, in a joint action with the city council of Grevenbroich and the “Gemeinschaftswerk Natur und Umwelt” of the Rhine district of Neuss, Germany.
The coloured house number is meant to symbolise that a lot of people in many different locations actively contribute to the conservation of diverse and ecologically rich habitats and thus invite people to participate in local discourses on the enhancement of biodiversity.
What is our goal?
We intend to demonstrate that every human citizen can contribute to the conservation and the enhancement of local biodiversity and that many people have already taken action.
