Opting for a clean energy source:
When we use fossil fuels like coal, oil, etc. We are creating a huge amount of greenhouse gas emissions. However, solar panels, wind turbines, hydroelectric dams, etc aren't used as often. Even though "renewable energy sources typically emit about 50g or less of Co2 emissions per kWh over their lifetime compared to about 1000g CO2/kWh for coal, and 475g CO2/kWh for natural gas." In conclusion, using clean energy will lessen the number of greenhouse gasses we emit every day, which will slow down global warming.
