Ianto Evans is a person who is well known for his work in natural building and permaculture. Natural building means using materials that come from the earth, like clay, sand, straw, and wood, to make houses and other structures. Permaculture is a way of designing gardens and farms that work with nature, instead of against it.
Think of building a sand castle at the beach. It's made out of sand, right? Natural building is like making a sand castle, but on a much bigger scale and with different materials. Instead of sand, we use things like clay, straw, and wood to build things like houses, walls, and even furniture.
Permaculture is like making a special garden where we plant certain things in certain places so that they help each other grow better. For example, we might plant tomatoes next to basil because the basil plant makes the tomatoes taste better and keeps pests away.
Ianto Evans has spent a lot of time learning about natural building and permaculture and teaching others how to use these techniques to make sustainable homes and farms. He's like a teacher who wants to help people learn how to build and grow things that are good for the earth and the people who live on it.
