Whale Stranding in New Zealand - by Athea

While learning to enter data into spreadsheets, we looked at the instances where there have been whale strandings in New Zealand. I chose to look at the years from 2012. My graph shows that there are over 152 whale strandings in New Zealand, by 2013 it started to decrease, and unfortunately, from 2014-2017 the number of strandings has increased. Knowing this information - makes me ask why?
