Garbage Patch And Marine Debris - One Result Of Human's Waste

We know that we, humans are always use plastics in their lives. Always and always, but our earth have difficulties to digest plastics. So, after using a plastics human will throw the plastics to trash bin. Then, it will be throw again to the sea with full of animals and other organism. Due to the large using of plastics all over the world and many of them are throw to the sea, the plastics are moved by the sea's current.

All of the trashes are moved by a current named North pacific gyre, it located in the northern of pacific ocean. This current has clockwise circular pattern. Many plastics and other garbage that trapped in the current have form a wide area consist of garbage.

Those garbage have form an garbage island called Great pacific garbage patch. People don't see this island because most sailor and fisherman are avoid this current due to the wind and large fish. This is very dangerous because in the north pacific gyre many organism lived there and their lives is disturbed by this garbage also cause death.

There are about 5 oceanic gyres in the world, so not only great pacific garbage patch exist, but also North atlantic garbage patch and indian garbage patch, and Great pacific garbage patch is the largest of all. Not only on the sea, but also on the beach. Both sea and beach have a large ecosystem that contains many organism. There are many garbage that floated on the sea, like Plastic bag, balloons,rope, cans, Styrofoam, fishing nets, ship debris and many more. But, Plastic constitutes 90% of all trashes floating on the ocean. The amount is about hundred millions of plastics on the ocean.
Sources of the garbage
Where the garbages come from? The garbage comes from many sources like Ships. Ship usually bring cargo, they bring it to distributes many things like toys to many destinations. On their way, usually storms come and destroy the ship or the cargo. If destroyed, the remains of ship and cargo will float on the ocean until it washed ashore in a beach. But, the remains can also float and flow by the ocean gyre then form garbage patch. But, this is for accident, accident can come everywhere and everytime. Beside accidentally pollution, there are human-made garbage that throw to the sea. This is the worst sour
ces,it's not accident. The unused garbages are always dump in the sea.

The Impact of garbage dump
Some people thinks that sea is the best place to dump garbage, because it won't reduce the usage of land and the garbage are not involved in their life, but what about the wildlife, they are all suffered from garbage that they mistaken it as a food.
For example a plastics, birds usually mistaken plastics as a food, so they give their son plastics to eat and for theirselves. Later, The plastics block the passage of the food and the bird can die due to the starvation and infection in plastics, other animal will do this too. Beside plastic, Ghost net, an abandoned fishing net that people leave it and float on the sea can be dangerous too especially for big animals like turtles and big fish.

Ghost net can make animal cannot move. They
will trapped in net, get difficulties to eat, and later cause starvation and suffocation.
The impact in environment is will make a place messy and dirty. It can attract insect and bring bad bacteria from the garbage and enter our environment and spread diseases. For humans, the danger is the disease, we can get sick from insec t that bring
disease from garbage. Beside that, we can get poisoned from the food we eat. The food that come from marine life such as fish and prawn have eat plast ics will get poisoned from plastics then we eat from those poisoned animal.
The removal and prevent of debris

The large amount of garbage can cause dangero us effects so many people try to remove the garbage and prevent the garbage dump. The eff orts are like remove garbage from the beach, pulverization and a great way is to recycle the plastic. We can use plastic garbage and recycle it to a benefical things such as toys, bottle and many useful things. For example, people make a plastic craft named plastiki. This craft can be used travel the sea. you can do it too, you can change the plastics into pencil case, vase, and other.
To prevent the garbage dump, people are star t to reduce the usage of plastics. Can you reduce it too?

For the great pacific garbage patch, some people have a project named project kaisei (Ocean planet in japanese). Their goal is to clean up th e pacific garbage patch.
