**Step-by-Step Text Solution:** 1. **Identify Human Activities Contributing to CO2 Increase**: The question asks for two human activities that lead to an increase in carbon dioxide (CO2) levels in the atmosphere. 2. **First Activity - Use of Vehicles**: One significant activity is the extensive use of petroleum-based vehicles for transportation. These vehicles burn fossil fuels, releasing CO2 as a byproduct of combustion. 3. **Second Activity - Deforestation**: Another major activity is deforestation.
