DOES MILITARY SONAR KILL WHALES?
In this report I’m going to argue against the concerns that a dolphin and whales conservation group have produced, and I will support my argument with evidences to prove my choice. I’m also going to use couple of charts and data to back up my answers.
A dolphin and whales conservation group have produced artificial report. For instance they wrote ‘whenever there is a military sonar exercises, up to 200 whales die as a result of sonar damage’, which was exaggerated, 200 whales and dolphins died just once and that was on Manila Bay, Philippines in 2009. When we look at the data we can see the average number of cetacean stranded is 28.2, and ranges from 1-200

The reason I put the second graph is because it said on my sheet to plot a bar chart of the number of deaths at the time of naval exercises on the axes (3. 1) – hope it makes sense
The secondary source from table one has a limited analysis; they have missed out so many years such as 2001, 2007 and they doubled up the year 2008, and it is in various locations. The second statement ‘Whales and dolphins are being damaged all around the world by military sonar exercises’ needs to be shown by having more locations that show that places with no sonar activity have no stranding. They have not told us how many military sonar exercises there were in one year or how many stranding there are when there are no military sonar exercises. They have also not told us how big the sonar exercises were so we cannot see if there were more stranding when the exercise was bigger.
According to cetacean experts the death of the dolphins and whales is not just because of military sonar exercises in fact stranding can happen for many reasons for example whales can become ill or old, sometimes they get confused by boats or even global worming may have an impact.
The third statement was that ‘Sonar damages the whales own sonar apparatus, causing them to beach and become stranded’ to give you a reason why the speech is wrong I made a graph from table 2 and I can see that the death of the cetaceans is increasing each year so that means that the causes are increasing too and we don’t know why and that is because we have a very biased research and limitation of information.

In conclusion, I would say that dolphins and whales have different reasons of dying in particular states as a result we can’t decide who to blame, so you should have a wider range of research to figure out the reasons behind the death.
