The article talks about using algae to make biofuels and other useful products because we're using up fossil fuels fast and polluting the environment. Algae can help without affecting our food supply like traditional biofuel sources might. Algae have lots of carbs, fats, and proteins that can be turned into biofuels such as bioethanol and biodiesel, as well as healthy stuff like omega-3 and carotenoids. Researchers are looking at how to pick the best algae, keep them clean, grow them efficiently, and easily get the useful stuff out. By using algae, we can make fuels and nutrients while being kinder to the environment.
