Paintings on canvas

I like to use natural materials in my paintings like sand, chalk, coffee, ash, tar, seeds etc.  I try to avoid oil colours and plastics like acrylic. When choosing my painting materials I keep in my mind environmental issues and sustainable development. It's important to me bacause I want to take part in saving the Planet Earth from the climate cahange and pollution. I have been succesful in my effort to make eco art. It's a great feeling when you get to that point.
