Reed, Betsy. “Food, Feed and Fuel: Global Seaweed Industry Could Reduce Land Needed for Farming by 110m Hectares, Study Finds.” The Guardian, Guardian News and Media, 26 Jan. 2023, https://www.theguardian.com/environment/2023/jan/27/food-feed-and-fuel-global-seaweed-industry-could-reduce-land-needed-for-farming-by-110m-hectares-study-finds
A new study suggests that seaweed farming could provide food, feed supplements, and alternative fuels, by growing on an area of ocean almost the size of Australia. The study estimates that if seaweed could constitute 10% of human diets by 2050, it could reduce the land needed for food by 110 million hectares, an area twice the size of France. However, the study also notes that there are potential negative impacts on marine life that will need to be balanced with the benefits. The study identified 650 million hectares as plausible for seaweed farming, with the largest areas in Indonesia and Australia.
As much as I do think it is important to reach out and find sources for biofuel in different parts of the ocean, it is ultimately important to protect the habitats that live in those areas. This is because the ultimate goal of biofuel is to help fight climate change, and with process of using seaweed and potentially harming the life that already lives in those areas, I feel like we are hurting the climate and wildlife around us, and that might not be worth it for the biofuel. It sounds hypocritical, like we are breaking our one promise. However, if we look at the positive effects we can additionaly see that seaweed farming may constitute 10% of human diets by 2050, which would reduce the land needed for food by 110 million hectares, as mentioned in the article, which would tremendously help human consumption and climate change. All in all, the article makes it clear that this method of seaweed farming is a double-edged sword in the end.
I completely agree with your take that we must be conscious about the habitats that reside in those areas. While this seems like a possible solution to world hunger and finding alternative energies, we must find a way to balance the ecosystems there and new implementations fo seaweed farms.
This is an interesting, innovative approach to solving our fossil fuel addiction. I agree with your sentiments about considering seaweed production a double-edged sword. Is damaging ecosystems worth the small slice of the pie this would take out?
Thanks for your comment. It is a hard question to answer since there are great advantages and irreversible disadvantages to nature. Biofuels are created to slow climate change and make our planet healthier, so if we destroy ecosystems and damage wildlife to get biofuel, aren’t we just being hypocritical?
I think we need to find some balance because seaweed farming can destroy the habitat however it can also be extremely beneficial. Do you think there is some sort of middle ground where we can responsibly use this resource.
Thanks for your question. To be completely honest, I don’t think there is a great middle ground where we can effectively and responsibly use this resource. These ecosystems are very fragile, and history shows us that we are not careful and respectful when given access to such an incredible and economically beneficial source.
