- Burning something is a kind of action
- If something occurs by performing an action, then that action is required for that something to occur
- Therefore, if something occurs by burning something else, then burning that something else is required for that something to occur

- If something occurs by burning something else, then burning that something else is required for that something to occur
- Natural gas is used for generating electricity by burning in a power plant
- Hence, using natural gas to generate electricity requires burning that natural gas

- Using natural gas to generate electricity requires burning that natural gas
- Natural gas is a kind of fossil fuel
- Therefore, using fossil fuels to generate electricity requires burning fossil fuels

- Using fossil fuels to generate electricity requires burning fossil fuels
- Hence, using fossil fuels to generate power requires burning fossil fuels

- Electricity is a kind of electrical power
- Electrical power is a kind of power
- Hence, electricity is a kind of power

- Using fossil fuels to generate power requires burning fossil fuels
- Electricity is a kind of power
- The burning of fossil fuels produces greenhouse gasses
- So, using fossil fuels to generate power produces greenhouse gasses

- Using fossil fuels to generate power produces greenhouse gasses
- Fossil fuels are a nonrenewable resource
- Hence, using nonrenewable resources to generate power produces greenhouse gasses

- Using nonrenewable resources to generate power produces greenhouse gasses
- If something causes an increase in something else then that something produces that something else
- Hence, using nonrenewable resources to generate power increases greenhouse gasses

- Using nonrenewable resources to generate power increases greenhouse gasses
- If something increases something else then decreasing that something will decrease that something else
- Therefore, decreasing the use of nonrenewable resources to generate power will decrease greenhouse gasses

- Decreasing the use of nonrenewable resources to generate power will decrease greenhouse gasses
- As the use of renewable resources increases , use of nonrenewable resources will decrease
- So, increasing the use of renewable resources to generate power will decrease greenhouse gasses

- If something occurs by burning something else, then burning that something else is required for that something to occur0
- To decrease something means to reduce that something
- So, using renewable resources to generate power reduces greenhouse gases

So, using renewable resources to generate power reduces greenhouse gases
Question: As the human population increases, more fossil fuels are being used. The burning of fossil fuels produces greenhouse gases. How might humans reduce greenhouse gases?
Context: - Fossil fuels are a nonrenewable resource
