This isn't bad but I think you need to beef up your 2nd point about how this invasive species affects us. Yes, it can choke up the river. Why is that bad? What will that do to to the surrounding habitat? How does this affect humans? That point isn't strong enough. I need to know why this is a huge problem. Your colors are off too. They don't match the order listed in your 5 points above. Let's start there and revise the 5 points to make this clearer and then we can work on the script.
For this quarter's project, my partner Dalson and I are doing it on the invasive plant, the red mangrove, which has caused problems. Check out this page for any updates I post.
