In response to the global climate crisis, many countries are implementing "carbon tax" policies, which impose additional fees on the use of fossil fuels to encourage businesses and individuals to reduce emissions. However, critics argue that such measures place a disproportionate burden on low-income households and are far less effective than directly subsidizing renewable energy. When weighing these two strategies, do you believe that a carbon tax remains the most equitable and effective tool for addressing climate change? Please state your position and provide specific reasons and examples to support it.
