Natural gas is considered more environmentally friendly than oil because it produces fewer greenhouse gas emissions when burned. When natural gas is burned, it releases about half the carbon dioxide emissions compared to oil. Additionally, natural gas combustion produces lower levels of air pollutants such as sulfur dioxide and nitrogen oxides, which contribute to air pollution and acid rain. Overall, natural gas is seen as a cleaner and more efficient fossil fuel option compared to oil. **

Oil, natural gas, and coal are not examples of sustainable resources because they are finite and non-renewable sources of energy. Once these resources are extracted and burned, they cannot be replaced within a human lifetime. Additionally, the extraction and burning of these fossil fuels contribute to environmental degradation and climate change. Therefore, relying on these resources for energy production is not sustainable in the long term. **

Organic products are made from ingredients that are grown without the use of synthetic pesticides, herbicides, or fertilizers, and are often certified by a regulatory body.
