Some greenhouse gases, such as fluorocarbons (CFCs, HFCs, PFCs, etc.), are human-made. Others, such as water, methane, and carbon dioxide, are naturally produced. Which type of greenhouse gas (human-made or natural) is more difficult to control and eliminate? Which types are easier? In three to five sentences, provide evidence for your argument.

Here is a good overview by EPA. There is a lot of useful information here although I don't know that it will answer all of your questions.

The type of greenhouse gas that is more difficult to control and eliminate can depend on various factors. Generally, human-made greenhouse gases, such as fluorocarbons, tend to be more challenging to control and eliminate compared to naturally produced greenhouse gases like water, methane, and carbon dioxide. This is primarily because human-made gases are intentionally produced and released into the atmosphere through industrial processes. Controlling and eliminating these gases requires significant changes in industrial practices, technology innovation, and policy measures. On the other hand, naturally produced greenhouse gases are part of natural processes and cycles, making it comparatively easier to mitigate their emissions by addressing the sources and adopting land management practices, agricultural techniques, and renewable energy strategies. Additionally, the natural sinks and reservoirs of these gases offer potential opportunities for their reduction or removal.

Human-made greenhouse gases, such as fluorocarbons, are generally more difficult to control and eliminate compared to naturally produced ones like water, methane, and carbon dioxide. This is primarily because human-made greenhouse gases are specifically engineered for industrial processes and applications, which makes it challenging to find alternatives. Additionally, these compounds are stable and have long atmospheric lifetimes, contributing to their persistence in the environment. On the other hand, naturally produced greenhouse gases are part of natural cycles and can be influenced indirectly through land management practices, such as reducing deforestation or addressing agricultural emissions. Efforts to control and mitigate naturally produced greenhouse gases can be more effective and achievable.
