Coral Bleaching- Aaron Hoffman

 




Coral bleaching is a huge problem all around the world. Coral bleaching is when these bright and vibrant corals turn completely white. Coral are bright and colorful because of microscopic algae called zooxanthellae. The zooxanthellae live within the coral in a mutually beneficial relationship, each helping the other survive. One of the leading causes of coral bleaching is global warming. As little as 2 degrees can cause coral to drive out algae. Other reasons are extremely low tides or pollution or too much sunlight. Coral bleaching matters because once these corals die, reefs rarely come back. With few corals surviving, they struggle to reproduce, and entire reef ecosystems, on which people and wildlife depend, deteriorate. Small, daily actions can help reduce coral reef loss, like reducing stormwater and fertilizer runoff or avoiding herbicides and pesticides. But if we really want to solve the coral bleaching problem, we must address climate change.

SABIC resins reduces the weight from things such as dashboards to tailgates by as high as 40% which makes it to where vehicles can go farther. The technology world is trying to convince everyone to convert to electric vehicles. They depend on batteries that charge faster, run longer, and are also more efficient.

Want to go on a cruise ship, think again

Image
              As well as a lot of other people, I enjoy a nice relaxing day on the water. Some people decide to take a weeks worth of days on the water. Including a boat, food, and entertainment. Cruise ships are some what of a luxury with the fancy dinners every night. Swimming pools and massive halls for shows and people to perform. Not to forget some even have places to throw cards and gamble. In recent study’s, cruise ships are found to be a major contributor to the growth of on water environmental pollution and degradation. This is also due to the ever so increasing amount of people taking cruises along with the industry booming in the way that it did. The recent popularity before COVID-19 had researchers interested. So they did a few study’s and found out the information above. Other dangers that cruise ships might present is potential danger to passengers/staff physical and mental health including land-based residents who live close to the port.  Some crazy things that happen wh

Ocean Fish Stock by Aaron Hoffman

  The worlds ocean fish stock is on the verge of collapsing. T he  International Union for Conservation of Nature , Jared Ferrie reports that the oceans have absorbed more than 93 percent of the heat generated by human activity since the 1970s, primarily through its large surface area, volume, and low albedo. Last year, the ocean was its warmest in 136 years of records. The increase in temperature has led to new toxic organisms and algae bloom that poison fish. Many specials are leaving their natural habitats in search of cooler areas. Since fish are leaving their natural habitat it causes a lot of problems for the fish in the habitat they move to. Food starts to dwindle down quicker that it should and the people that eat fish can search for fish in that area but cast find any if the fish leave. People are also overfishing and causing species to decline.   https://youtu.be/AHI-B-4c2NU  https://www.newsecuritybeat.org/2017/02/ocean-fish-stocks-on-verge-collapse-irin-report/
