In week 5, we accepted the challenge that was given during the LEGO Build the Change webinar. The students offered their solutions on how to save Grimsville. Grimesville has a new name - Brightville. There is no waste that pollutes the town. There are waste sorting bins everywhere. The waste is taken to special recycling factories. They have filters to purify the air. Trees and other plants in green parks also purify the air. The water in the river is clean. The boat that uses the energy of the water for navigation collected all the plastic bottles and now takes care of transporting the organic waste to the fields. A water tank is used to irrigate the fields. Wastewater is collected, purified, and then used for irrigation. Many plant and animal species have recovered. The town has windmills to generate electricity, and all houses and buildings have solar panels. People are happy in their new jobs. Children enjoy riding skateboards and bicycles. Adults use public transport and electric cars. Hygiene is constantly maintained in Brightville. A green future shines bright in Brightville.
