Bringing the reefs back to life

In the last three decades, half of the world's coral reefs have died and if we don't act now those oceans 

treasures will be completely gone by 2050. It would be the destruction of an entire ecosystem, and with it, ourselves. That is why Naomi and I thought it is important to do something against this threatening thing that happens with these reefs! There is a group of people that started to replant reefs, that fell off in the ocean to ensure the survival of them.  

 

 We want to find out more about this project and how they proceed. How does the replanting work? Does it  make a difference or is it all for nothing? How much time will it take to replant enough reefs to ensure their survival and with it ours?

Circular building

Buildings cause 30% of our CO2 emissions. In Switzerland, around 17 million tonnes of building rubble (Bauschutt) are produced annually. Can this demolition material be returned to the cycle?
