Final answer:
Bamboo and banana fibers are renewable resources because they can be sustainably harvested and regrown, and the fabrics made from them are biodegradable and compostable. option b is correct.
Step-by-step explanation:
Bamboo and banana fibers are considered renewable resources because they can be regrown at a rate that matches or exceeds the rate at which they are used. Unlike non-renewable resources, which deplete over time and cannot be easily replaced, bamboo and banana plants can be sustainably harvested and regrown, ensuring a continuous supply.
These plants do require nutrients and water to grow, but they typically need fewer inputs compared to conventional cotton, which often requires significant irrigation and pesticide usage. Furthermore, fabrics made from bamboo or banana fibers are biodegradable, which means they can decompose naturally, returning nutrients to the soil and reducing waste. In addition, these fabrics can also be easy to compost, thereby contributing to a more sustainable and circular textile economy.
However, it's important to note that just because a resource is renewable does not guarantee its limitless availability. Sustainable management practices are essential to ensure that bamboo and banana plantations do not deplete the environment of necessary land, nutrients, and water resources.
