 village. And I, and I am eight years old, and I have a question. Why is algae bad for the environment? Hi Kanaya, and thank you for your excellent question. I'm Colonel Andrew Kelly. I'm the district commander for the Jacksonville district U.S. Army Corps of Engineers. And first, I just want to tell you not all algae is bad. Algae are organisms that live all over the planet. They come in all shapes and sizes and colors. You've got blue and green and brown. There's over 27,000 different kinds of algae and some grow on turtles and even on polar bears, although I've never seen them on a polar bear. But you're right, sometimes algae is bad, especially when it covers a water body. When it does that, it covers the whole top and blocks the sunlight from other plants and animals and denies them food because it's so hungry and grows so fast. And some algae get smelly and release stuff into the air that make us sick and cough, and that's not good for people either. But the good news is there are engineers and scientists all over the world, including the Corps of Engineers, that are working really hard to help fix some of that bad algae. So thanks again Kanaya for your thoughtful question. Keep studying hard and asking those tough questions because you and your friends someday will be helping us find the tough answers to those really hard questions for a healthier and more sustainable future.
