The aquatic ecosystem
The aquatic ecosystem is not as valued as it should be. If about 75% of Earth is covered by water shouldn't we make a bigger effort to protect it? The greenhouse effects are changing the climate of the Earth which in turn is warming the waters, depriving many species of much needed nutrients and triggering deadly coral coral-bleaching events. Unusually high temperatures this year could speed up the destruction of some of the most important habitats in the world. This can and has had devastating effects on the population of many large predators, like sharks and swordfish. This could seriously put the natural food web out of whack. Over fishing is also a huge problem, and if you'll believe it fishermen are going farther away from shore and fishing farther down on the food chain to try and hide what a big problem this is! Something to kin of think about is of all the biomes we studied in ecology so far this year only one of them was an underwater community, the coral reef. This tells me that information about underwater habitats is NOT being passed along very well. Just remember the next time you don't recycle a can, or dump chemicals down the drain, every living thing under the water is the same as up here. There are herbivores, omnivores and carnivores the same as on land, just a little more distant. So please keep our ENTIRE environment in mind.
