In The News: Rising Ocean Temperatures Threatens Global Fish Supply

The World Is Losing Fish to Eat as Oceans Warm, Study Find


Dr. Chris Free from UC Santa Barbara recently published in  Sciencedramatic study indicating warming ocean trends are impacting fisheries more than previous predictions. Poor fisheries management in combination with climate change have typically shared the blame. This study separates the negative effects of climate change alone which paints a much more dire picture of future supply chain impacts. A 4.1 percent decline in available fish supply since 1930's was noted- this number is equivalent to nearly 1.5 metric tons of fish. Not only will this greatly threaten many coastal communities who rely on 70% of their protein from fish sources, but the economic survival of entire industries depend upon healthy fish supplies. 
Regulations need to be updated to reflect the effects of climate change. Stricter and more sustainable management approaches must be undertaken across the globe. 

"Amid these changing conditions, fish are shifting where they live, in search of their preferred temperatures. High ocean temperatures can kill off both the fish themselves and the sources of food they depend on."-Dr. Free

“Fish are like Goldilocks: They don’t like their water too hot or too cold,” said Malin L. Pinsky, an associate professor in the School of Environmental and Biological Sciences at Rutgers University and a co-author of the new study.

    This is terrible! I particularly like fish very much. It is truly devastating to see the more of the worlds supply is disappearing due to our poor habits. Our contamination ways have got to stop before we starve ourselves or poison ourselves to cancer!

Blog #26 RF and your Health

When I opened by phone and looked at the "legal" tab under settings- I was shocked. Quite a bit of information is held there. However, it says that my iphone "has been tested and maintains and meets applicable limits for radio frequency (RF) exposure" But How do I know? What does the evidence say about this? Most reading I could find came from the EU. What does America have to hide? Well it seems this a race to technology , and not about human health. Every article I searched talked more about how we need to "win" 5G and "beat out China" in our sprint to the finish to get 5G networks up and running... Should we be concerned that 5G is headed our way ? The industry tells us it is "the next great thing" "Will give us more speed"...But is this good for our health? Do we care about RF exposure in this country. Here is what our commission on   Federal Communications has to say about it: The  FDA maintains a...

Blog #1 My Home Assessment

Did you discover any environmental risks in your home by completing the home assessment ? Yes! By completing my home assessment I realized many things about my current home, and considered past risks associated with my many living situations throughout my life.  My current home was built in 2014- although the original 1942 structure still partially exists. Our living room and original foundation/roof were retained when we purchased and remodeled our home into it's current modern iteration. The old windows, interior paint were all removed. The exterior paint still remains, deeply buried under many layers. I also wonder if the original insulation still remains inside the walls... We do not have a basement or attic that is accessible. But the crawl space under the home is where we store many items. Christmas decorations/lights/lawn tools/ chemicals and old paint cans. We do not use a pesticide company but do locally spray pesticides around areas of our home in response to ants/...

Blog #23: Climate Change

How can we strengthen our voice as nurses for climate change? A 2018 article by the American Academy of Nursing on Policy recommended 8 principles for nurses to take a lead on bringing this critically important issue to the forefront: 1. Reduce sources of pollution that contribute to climate change . a. Mobilize, focus, incentivize, and increase national funding for climate protective actions. b. Oppose any rollback of climate protective polices addressing fuel economy standards, power plant emissions, and other sources of atmospheric carbon. c. Support climate protective initiatives at the community level, emphasizing the needs of populations and communities most affected. d. Advocate for community actions to incorporate renewable sources of energy, more fuel-efficient options for transportation, waste management, agricultural and forest management, and more energy-efficient buildings. e. Promote environmentally sustainable practices (e.g., reduction of medical waste) througho...
