Boa Constrictors are endangered because of predators, cold weather and believe it or not, humans. Humans cut down lots of jungles and forests where these snakes might live.They build lots homes, and by doing this, they are taking away the Boa Constrictor's homes. The Jaguar is the enemy that eats the Boa. The Boas could be endangered because the Jaguars are hungry. Also, it could be because of cold weather. Snakes are cold-blooded and could freeze to death in the cold.
Ever since ancient times, reptiles such as snakes have lived on the earth. When humans started living on earth, snakes like Boa Constrictors were driven away because there were more bare places with no jungles or forests, and that meant endangerment to some of the snakes like the Boa. There was more pollution, noise, and less homes for the Boa Constrictors. So now, you can see why they're endangered. Sometimes, when you try to make the world a better place, you don't stop and think of what you are destroying.
