Marine Habitat Destruction

by Valeria Torres

Why is it important?

You might think that there is too much water for the threat of habitat destruction to become an issue, but the ocean stability is slowly starting to fall apart. The ocean is our main source of oxygen in the atmosphere and absorbs most of he carbon in it. It contains most of the earths biodiversity, and most of the protein we eat each day. The distance between you and the ocean doesn't matter, it will still affect the water, air and food that you use everyday. The ocean also contains 99% of the living space on Earth, and also gives us 70% of our resources more than land can offer. The deep-sea is our planets life support system.

The Causes of habitat loss

Bottom Trawling

Bottom Trawling is a fishing method where a substantial net is dragged along the sea destroying and taking up everything in its path, including massive amounts of creatures an habitats. It has captures 800 million pounds of marine life in 2007, increasing over the years.

Runoff and Sediment Suspension
Building cities and towns near water can be ideal, but there is problems that can be caused. For example runoff, it occurs when there is more water than land can absorb, the liquid flows into nearby water sources and eventually into the ocean. Sediment suspension occurs when soil is uncontrollably entering the water and blocks sunlight from getting to the plants and animals, maybe even causing them to die.

Vegetation removal

Removal of greenery can destroy and damage habitats and can introduces sediment suspension.


Dredging is the act of removing unwanted accumulation in water pathways. It destroys and removes habitats and introduces sediments in the water.

Destructive Fishing Activity

This mainly points to over fishing, bottom trawling, ghost fishing and by-catch which is using poison and explosives. Over fishing means to catch more fish that the ocean can produce. Ghost fishing is a lost or any abandoned fishing gear that continues to trap and kill marine life.


Unwanted plastic or any type of trash that is with you should be discarded in the trash not the ecosystems. Every year massive amounts of trash are being thrown into the oceans and increasing every year, endangering countless amounts of marine life.

Helping out the ocean

Take an our or two during the week and help clean up the shore by removing plastic bags and other trash.

Staying away from harmful marine products

Reduce your water/energy use

There are many simple ways you can help reduce your energy use. For example, taking shorter showers, turning off the lights when your not using that room, use high efficiency appliances, ride a bike or walk instead of using vehicles.

Inform other people about the ocean

Learn about the oceans ecosystems and share your knowledge with your loved ones.
