Mercury pollution in our oceans:
Pollution is high in our oceans, and mercury is included. The part that is scary (for you meat eaters) is you will end up consuming it at some point. Whether you eat fish daily, weekly, or yearly, you will consume some mercury. Mercury levels in oceans are predicted to rise and if they rise like they say it will, the amount of mercury in the Pacific ocean with increase by 50% in the next 40 years. Mercury has already contaminated some body of water in every state, and of course including the oceans. Most of the mercury pollution comes from coal plants and most of mercury is found in Tuna. Studies show that Americans eat approximately 3 pounds of canned tuna every year, making tuna the second most popular seafood in this country, being behind shrimp. Fish with more than 0.5 parts per million or (ppm) can be removed from the store's shelves. This woman named Deborah Fellner starting losing her hair, her speech started slurring, her memory started to fail and her heart started to flutter. She "Collapsed" in the parking lot of a supermarket one day and woke up with a crowd of people surrounding her. She went to see multiple doctors who didn't know what was wrong. Finally after her husband saw something on TV about mercury, she got a blood test, and sure enough they found 48 parts per billion of mercury in her. That's 10 times what the "Environmental Protection Agency" calls safe. Be careful where you get your fish from, where it was caught and how often you eat it, you don't want to get sick from it. There are ways to help stop the mercury problem such as buying thermometers without mercury. A small amount of products need mercury to work like fluorescent and high-intensity-discharge lighting, but those things are still better for the environment because they are highly energy efficient, meaning they take less power made by coal burning power plants, which release a large amount of mercury into the air. By using and then recycling these items we can minimize the amount of mercury released into the air. Make sure you recycle these items, you can contact the hazardous waste collection program. Hennepin county programs and pollution control equipment have worked together to bring down the levels of mercury. They've brought down mercury levels from 456 pounds in 1990 to less than 21 pounds in 2000 reducing it more than 95%.

Age of Mammals-Cenozoic Era:

  • The Cenozoic Era took place 65 MYA and we are still in it today. The Continents looked very different during this time, here is what they looked like:
  • As you can see, the continents are closer together and some of them are connected. Australia is practically connected to Antarctica, and Africa is way closer to South America.
  • 65myaEarth.jpg

  • So far this Era has lasted 66 MY All together.
  • The Cenozoic Era was separated into 3 different parts:
    • The Paleogene Period: 65-23 MYA
    • The Neogene Period: 23-2.6 MYA
    • Quaternary Period: 2.6 MYA
What was Earth Like?
  • The Earth was much warmer, the overall climate was much more consistent with the weather.

  • During the Paleogene Period, there was a Paleocene-Eocene Thermal Maximum that took place 55.8 MYA.
There was a long cool, dry period of time.
  • Each period of time during the Cenozoic Era had a different climate:
    • The Paleogene Climate was Tropical.
    • The Neogene had a drastic cooling, which continued into the Quaternary Period.
The Changing Landscapes:
  • The Continents drifted apart during the Paleogene Period creating vast stretching of ocean.
  • During the Pleistocene Epoch: Glaciers covered central North America as far east as New York, also to Kansas and Nebraska
all the way to the Northern West coast. The Great lakes were formed as the glaciers receded.
  • Popular mountain ranges including Alps, Himalayas and the Rocky Mountains formed during the Cenozoic Era.cenozoic-era-info0.gif
  • Life During The Cenozoic Era:
  • The extinction of groups of giant giant mammals, aloud more of the smaller species to survive because their predators were all gone.
  • During the beginning of the Paleogene Period mammals that survived from the Cretaceous period, still lived.
  • Later in the Paleogene, rodents and small horses called Hyracotherium, rhinoceroses, and elephants started to appear. Then even later in the Paleogene dogs, cats, and pigs became common. Along with flightless birds call Diatryma.
  • In the Neogene Period, early primates and early humans appeared along with cattle, sheep, goats, antelope and gazelle.
  • Here are some photos of these animals:

  • When the Quaternary Period began, cave lions, Sabre cats, cave bears, giant deer, woolly rhinos and woolly elephants appeared this was like the Ice Age.
  • During the Cenozoic Era: Plant life flourished. Nearly every plant alive today was living during the past Cenozoic Era.
  • Forests took over most of North America, but they died off as the climate cooled, leaving open land.

  • Widening of the Oceans: Sharks, whales and other marine life lived. The Great lakes formed during the Eocene Epoch, they were Great homes for bass, trout and other fresh water species.
  • As forests thinned, grasses spread over North America, and savannas covered the land. The common plant life was pines, mosses and oaks.
  • Flowering plants and edible plants dominated in the later part of the era, as humans worked the land.

And That is the story of The Age of Mammals and about the life during the Cenozoic Era!
