Estuaries are the basis of life for most marine
animals. Living there does not come easy to the animals. You
may not know this but the tide changes the amount of salt and
freshwater in and estuary twice a day. As the tides change the
animals have to adjust to the salt and fresh water differences.
Sometimes the animals choose to leave at high tide or low tide
but others just take the time to adapt to the changes. This is
just one of the situations animals in estuaries have to adapt
or put up with.
We have come
to a point in time where
the
estuaries need our help the most. They have to put up with the
oil spills, which is a very bad thing for them. It is happening
to animals all over the world as we speak. As you can see by
the picture, we should do as much as we can to help these animals.

Unfortunately, NASA is using saltwater marshes as a dump if their space shuttles crash after take-off ("Salt Marshes and Mud Flats."). All different people have their different thoughts about everything; NASA believes that they should have a crash landing area in a salt mash far away from people. They do not take the time to realize that there are about 2,000 species living in the salt marshes they use. The space station claims that they are helping the salt marshes by cleaning them but it is nearly impossible for them to clean the pollution that they are causing. Another thing that they do is they flood the salt marshes with water so the mosquitos won't lay their eggs. This does not only affect the mosquitoes but it also kills many of the plants, and therefor animals.
