Glass beads are made from fossil fuels. This process releases greenhouse gases into the atmosphere. This is a big concern in today's world, as it can lead to a lot of pollution. Luckily, glass beads are made of renewable natural resources, including sand. Sand is produced from rocks that decompose over time, and it takes thousands of years to form an ample supply. Because of their environmentally friendly properties, they are an excellent choice for many crafts.
