oil spills and its effects!!

This article is informing us about what are oil spills and how they affect the enviorment the marine life and the consequences of them!
What is an oil spill, when do they happen?
An oil spill is when oil goes into the ocean because of different human activities, or natural disasters for example:
-when people make mistakes or are careless and cause an oil tanker to leak oil into the ocean.
-When countries are at war, one country may decide to dump gallons of oil into the other country’s oceans.
-people dump crude oil into the oceans because they do not want to spend money on decomposing their waste oil.
- natural disaster may cause a oil tanker to spill, and others!
What are the consequences of an oil spill?
Because of one single oil spill, millions of animals die, causing the enviorment, the food chains and the ecosystem break!!!
millions of birds die from oil spills if their feathers are covered in oil. The bird will then be poisoned because it will try to clean itself. Animals may die because they get hypothermia, causing their body temperature to be really low. They may die from really low body temperature. Oil may also cause the death of an animal by entering the animal’s lungs or liver. The animal will then be poisoned by the oil. Oil also can kill an animal by blinding it. The animal will not be able to see and be aware of their predators. If they are not aware of other animals, they may be eaten.
Scientists have discovered that after a simple oil spill, its extremly difficult for animals to recover and that ten years after the spill, animals are still affected by it!
Oil spills sometimes are the reasons of animals becoming endangered!!!!!!
My opinion:
I think that this artice is very important because when people hear about a oils spill, they usually think about a little bit of oil in the sea that killed some birds (thats what i thought an oil spill was), but this article actually tells you how it affects millions of animals, and the whole marine life! And after reading this article, you can see that only because we (humans) are too sellfish, or not consious, we end up killing millions of animals, and affecting the whole marine life! I think this article is very good, and really makes you think how this is impacting the enviorment and that we need to be carefull in what we do and how we do things because oil spills are not just something that will da,age for one day, and be perfect the next one, it impacts so much, and after years and years, the harm will still be there!!!! I think this was a very interesting article that more people should read , and become aware!!!
