The notion of sustainability revolves around practices that meet present needs without compromising the ability of future generations to meet their own needs. Methods of sustainability generally focus on reducing environmental impact and promoting ecological balance.

Using biodegradable materials, recycling, and planting new trees all contribute positively to environmental health. Biodegradable materials are designed to break down naturally, thus minimizing pollution and waste. Recycling conserves resources and reduces energy consumption by reprocessing materials instead of extracting new raw materials. Planting new trees helps in offsetting carbon emissions and restoring ecosystems that have been affected by deforestation.

In contrast, increased fossil fuel consumption is not aligned with sustainable practices. It typically leads to higher greenhouse gas emissions, air pollution, and depletion of non-renewable resources. Therefore, C stands out as it is contrary to the principles of sustainability, making it the correct answer for what is NOT an example of a method of sustainability.
