PBS videos.

Sea level rise everyday and its usually due to climate changes. This winter was a very unusual winter due to the warmer weather. With this warm weather, it causes the ocean levels to rise. I also didn't pay attention to the videos because they were boring. If they had more interesting facts it would be easier to pay attention.

BBC documentary

I personally didn't liked the video. It was boring and couldn't pay attention. All they talked about was global warming and how it was caused by humans. I disagree because nature could play a role in global warming as well as humans. Yes we are polluting the earth but mother nature has her duty too. I also didn't watch most of the video due to not being at school. So i have no idea what happened the first day.

blah blah blah....

I didn't really learn much from my project. Mostly because it happened in 1556 and wasn't enough information. One thing I did learn was that its the only natural disaster with the highest death toll ever. The earthquake killed about 830,000 people. It also affected 97 countries and killed 60% of their population. In modern time estimates, people would say that it is an 8 on the magnitude scale. That is all.

Earthquake in Japan = Hurricane Katrina

The documentary about the earthquake in Japan was truly a natural disaster. It may not have caused that much damaged on the outside, but in the inside it did. With just that short earthquake, plates in the ocean shifted causing the tsunami, which then caused a disaster. The tsunami destroyed thousands of acres of land and homes, and also killed many. Japan usually have minor earthquakes that don't cause that much damage. That is probably why they weren't expecting a tsunami. Some things we can learn from this event is to predict a little into the future. If they new an earthquake was coming, they need to think of the consequence that could happen after. Whether it is an after shock or a tsunami, the residents should be alerted. Also since the tsunami, nuclear power plants have been leaking radiation into the air, which is harmful and even causing deaths. Another thing we could learn is to study geographic maps of the land and sea. If they knew where fault lines were, then that could lead to other diasters being prevented. The japan earthquake is something similar to what happened in the United States. Hurricane Katrina was a massive hurricane the hit the Gulf of Mexico in 2005. The hurricane destroyed land in Lousiana, Alabama and Mississippi. The hurricane started near the Bahamas and moved its way up north. Many places in the south were flooded for days, even months after. The hurricane caused many deaths and many others were injured. So like the earthquake and the tsunami, if we would of had a better way to find out when and how strong the hurricane was, most things could of been prevented. The top picture is of Japan and the lower is of New Orleans after the disasters.

Whaddup water pollution?

Have you ever thought about what kinds of pollutants are in your water? Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks, uses, or lives in it. Their are different types of water pollution. For example: nutrient pollution means that there is too much nutrients and it creates weeds and algae. Oxygen depletion is when too much biodegradable material is added to water, the number of micro organisms increase and use up the available oxygen. Ground water pollution is when drinking water coming from aquafers are polluted. Surface water pollution is when oceans, rivers, or lakes become polluted. We detect water pollution by small samples of water can be analized in a lab to detect water pollution or they can find water pollution through organisms that live in purified water. One of the largest water pollution disasters has recently happened. It was the 2010 BP oil spill in the Gulf of Mexico.

cow poop is good? hmmm....

One farmer started using a machine called a digestor to make his cow poop into energy. It was created to that when you get rid of cow poop, it won't pollute the surrounding area. Another reason why it was created was so that the U.S had a newer and cleaner form of energy. He heats his house with this poop energy and he actually gets paid by the electric company. The digestor also can maake bedding and fertilizer. He also saves money by doing this too. The digestor transfors tiny bacteria particles to methane used for power, and leaves a liquid for fertilizer and a solid for anything else used. This process does take at least 20 days but it is still a huge money and energy saver. The only bad thing about the digestor is that they are not sure if it will create a water pollutant from all the run off poop. This can be done with either cow or pig poop. So now you know that cow poop is good for the enviroment. :)

BP oil spill.

The BP oil spill happened a few years ago in the gulf of mexico. An oil well exploded and tons of oil started leaking and damaging the waters and land. They tried many different ways to stop it and one of the ways was with a containment dome. A containment dome is a 4-story 70 ton structure the company planned to lower into place over one of the 3 leaks to catch the escaping oil and allowed it to be pumped to the surface. They wanted to install a shut-off valve at the site of one of the leaks. Floating booms were also used but were damaged by heavy winds. They also wanted to try cementing, which would seal the well to control pressure from the oil and gas beneath. Another thing they tried to install was a deep water valve, which would be used as a cut off of a last minute resort in explosion. Another device they had was a blowout preventer. The blowout preventer was a device to seal leaks. It did not work properly because natural gas started to seep through the wells. Two other main groups involved in the oil spill was Transocean and Halliburton. BP leased the rig from Transocean, while Halliburton was providing several services on the rig. They say that Halliburton will not be at fault but Transocean may have some investor worry.
