I've heard that the ozone hole is growing. Is that true?

Yes, the ozone hole is growing. It has been getting larger and larger since the 1980s due to human activities such as air pollution. The ozone layer acts like a filter for UV radiation from the sun, protecting life on Earth from harmful UV rays. As the ozone layer gets thinner, more UV radiation reaches the surface of the planet, which can lead to increased rates of skin cancer in humans.
