Human impact on dolphins

For this task it was Humans vs Animals.

We had to write a explanation about how humans impact your animal.

What impact do humans have on dolphins

Would you believe me if I told you there is a pink dolphin swimming around in the shining blue amazon river. You wouldn’t would you, you would only think that there are only blue, black and white dolphins. Well this is about them, yes the pink dolphins it’s also about the ordinary one’s as well and how you affect them.

What does impact mean? Impact means you have a strong effect on that person or thing. For example a struggling student who needs special attention and/or needs help with their learning, social skills or their physical education. That teacher has an impact on that student by helping them with that particular problem. Also another example is a tornado came through a farmer's land and recked all his crops. That farmer might have been relying on those crops for the money he got from the market when he sold them. He might’ve had to sell his great great grandma’s vase or had to sell some of his land. That tornado made a great impact in a bad way for that farmer but the struggling student was impacted by the teacher in a good way.

My first point is about overfishing and catching dolphins in nets. Dolphins, sharks and other big sea animals are impacted by overfishing because fishermen take more than they should. They take millions of fish when they should take less which makes dolphins starve which they have to go to more dangerous parts of the sea to get food. Which comes to my next part about nets and hooks. Since the dolphins have to go to the threatening waters that’s where the boats with the nets and hooks are. 300,000 whales and dolphins are dying from fishing gear a year.

My second point is about chemical spills in the ocean. In 2010 The deepwater horizon oil spill affected the dolphins who lived in the area. Some got lung disease, hormonal abnormalities and 128 deaths of dolphins and whales and they also found out that 6,400 marine mammals may have been harmed because of the BP oil spill. Following the oil spill there have been high numbers of stranded dolphins in Louisiana, Mississippi and Alabama. Since dolphins have to come above the water to breathe they can inhale chemicals which can cause lung cancer. It also burn’s membranes around the eyes and also can irritate the skin and inflame the skin. 

My third point is about illegal feeding and boat strikes. The Marine Mammal Protection Act made in 1972 made feeding  dolphins illegal and you can get fined to up to 200,000 dollars and a year in prison. The reason for this is because they would train their calves to beg for food instead of hunting. This is very dangerous because if they begged someone could hurt them or the dolphin could hurt the person which would be bad because the dolphin could get put down or something similar. Boat strikes are dangerous and one of them happened in sydney australia. Two of the rarest animals in the world were harmed during a boat strike. They were two out of the three snubfin dolphins at Roebuck bay. There are 161 identified snubfin dolphins in coastal waters around the tourist town broome. 124 were photographed and 63% bore scars and cuts.

My fourth and final point is about habitat degradation and climate change affecting dolphins. Habitat degradation is the loss of the places they live because humans destroy all the places that dolphins need to survive. Instead they have to settle for less favourable places that don’t have enough food or have the wrong temperature. Climate change is also another problem. The climate is changing fast and some dolphin populations may not have enough time to adapt. The sea temperature, freshening of seawater and the rises of the sea. The warming of the planet is causing a loss of habitats for dolphins. It is also affecting their timeng and ranges of their migration and also their reproduction. 

In Conclusion you know what we do with those pink amazon dolphins and those snubfin aussie dolphins and even the normal blue, white and black dolphins. We need to make a change and we need to do it now. The end.
