List four benefits to human life by eliminating the use of CFCs.

Explanation

### Step-by-Step Solution:

1. **Understanding CFCs**: CFCs, or chlorofluorocarbons, are chemical substances commonly used in refrigeration and aerosol propellants. They are known to be harmful to both the environment and human health.

2. **Impact on the Ozone Layer**: CFCs rise to the stratosphere and catalyze the breakdown of ozone molecules. The ozone layer is crucial as it protects life on Earth by filtering out harmful ultraviolet (UV) radiation from the sun.

3. **Benefits of Eliminating CFCs**:
- **Benefit 1: Recovery of the Ozone Layer**: By eliminating CFCs, the degradation of the ozone layer will slow down, allowing it to recover over time. A healthier ozone layer means better protection against harmful UV radiation.
