Don't worry, your beloved red roses won't become blue overnight, but an increase in UV radiation produced by the ozone layer's deterioration in recent decades has led flowers all around the world to change. According to a 2020 study led by Clemson University experts, UV pigmentation in flowers has grown over time, resulting in pollen destruction. Although we cannot perceive the color change with our eyes, it is a major issue for pollinators such as bees, who are drawn to the rich colors produced by flowers.
