Sea squirts were first found in the Northern Native waters, and are now world wide. In the New England area they range from Virginia to Maine. Each year the amount of Sea Squirts doubles in an area. They are one of the most common non-native species in the New England area.
They change out ecosystem, by killing and eating our food they we fish for everyday. Such as oysters and mussels, they will go into their shells and squeeze them until they die and eat their bodies, and using their shells as a home. By killing the animals we fish, they are making it so we have limited product to fish, and so we don't have enough to feed our families.
They usually pray on smaller animals such as mussels, oysters, and baby fish. When going after a baby fish or a mussel or clam, they wrap their bodies around the species, and release a toxic substance into the bodies killing them instantly. After killing the animals, they later take over their habitat.
There really isn't anything people can do to reduce the impact of Sea squirts only because they are so wide spread, and they keep coming and coming. Even if they tried to get rid of them, all it takes is one little one left behind to keep reproducing and they grow more and more and keep spreading. They are not harming man kind, so there is no reason to harm them.

Types of Pollution Affecting Animals
There are many types of pollution that can kill animals, but here are some of the major ones. Noise pollution, which is mainly in zoos, can eventually kill some animals, when all the other animals are loud in the zoo; it reduces the ability for the birds to communicate eventually making them feel alone, when this happens they will start to pull their feathers out.
Oil Pollution. Each year 500,000 birds are killed from oil pollution. The oil destroys their habitats and coats their feathers. Usually their feathers are water proof, but when it comes to the oil, it is to thick. The oil makes it so they cant fly, it also gets on their skin and burns it and eventually kills them,
Light pollution. People might not know this, but the bright city lights and the street lights affect the birds. It blinds them making it so they cant find their way to their home. It also causes birds to crash into one another and end up dieing. Light pollution also messes up their flight patterns causing them to fly to the wrong places.
Water pollution. When items fly out of your car window, or even out of your yard, they all end up in the water. The birds think it is food and ingest it, the things either stay in their stomach releasing toxins, or get caught in their throats killing them. Also heavy metals and pesticides are leaked into rivers and lakes killing the fish, which makes it hard for the birds to get food.
All of those things are the different types of pollution killing birds. It’s a really bad thing that is also hurting our economy. If it doesn’t get resolved many birds could become extinct and endangered. People have to do what they can to help stop these things from happening.

Sea Turtles Harmed by Plastic
Sea turtles are an animal that people don’t think about from day to day. They think about their house pets and nothing of those that live in the wild or even in the ocean. Sea turtles are facing extinction if we don’t stop throwing our plastic bags out the window. The sea turtles see the plastic bags and think it is food such as dead jellyfish. And when they try to eat it, that plastic stays in their stomachs. Over 100,000 sea turtles have been killed from plastic in their stomachs. Leather Back Turtles are threatened with extinction because of the plastic in the ocean, and if we don’t stop, then in 10 years they will be gone. So we need to do what we can to get sea turtles healthy again. So stop throwing your plastic out the window, because it ends up in the ocean.
