The Gulf oil leak is hurting all the organisms in the water.  Not only are the organisms living in the water feeling the effects, but others are too.  The pelicans have been covered in the nasty oil.  More than 65 miles of Louisiana shore line has been covered.  Two major pelican rookeries are filled and many marshes.  They are now using chemicals to break down the steady flow of the oil.  This solution is safer for the birds and keeps the oil away from land.  The fish are usually incapable of handling the harsh chemical and are usually killed.  The chemicals migrate fast and effect many fish in many areas.  I do not believe this is the right solution.  I think they should take the fish into consideration and not just the birds.  This oil spill is taking a harsh tole on these poor organisms.

For the biome project that was presented to be in my biology class, I chose to learn about the temperate deciduous forests. I picked this one for only one reason really: I really enjoy being out in the woods, and so I wanted to learn a little bit more about the area that I spend a lot of my time in. I really enjoyed learning about this temperate biome to be honest. It is quite amazing how diverse the forest is. From its animals, all the way to its plant species, the forest has a wide variety of incredible sights to see. The biome I chose was not the only interesting one. I must say that the in-class discussion that we had really opened my eyes to the world around me. Other biomes, such as the tundra, savanna, and desert were all very interesting. I also enjoyed the discussion because it was outdoors, which made me feel a little bit more close to the biomes. I know, that sounds rather odd seeing as I was no where near a desert. I mean the deciduous forests, which are everywhere in New England. I think I will conclude with the statement that I actually did enjoy this project, seeing as it brought me  a little bit closer to nature.

I had an idea prior to the biome project in biology class of how different parts of the Earth were from the others, but hearing from classmates on these major biomes was even more enlightening.  I was introduced to many biomes that were more unique than I had guessed.  The biomes also had some similarities with each other as well as differences.  Because I had a prior interest in marine life and ecosystems, the aquatic(especially salt water) biomes really captivated me.  The amazing range of life and unique biodiversity of oceans the world over are truly fascinating.  The fact that so many unique species can live together in one body of water is astounding.  The physical wonders of the ocean are also enthralling.  The enormous underwater mountain ranges, deep sea trenches, and desert-under-the-sea look is beautiful. 

It makes you sad to think that people are so careless about these delicate biomes and do truly stupid things like, say, drill in the Gulf of Mexico and accidentally have their oil rigs blow up, releasing millions of gallons into the water.  It’s hard to imagine the loss of life that will occur due to this BP oil spill.  Hopefully the people that care about the aquatic biomes of the planet will find a way to help.

An assignment we had to do in biology last week was find information on a biome and create a brochure on it. I did marine biomes. Other people did freshwater, tundra, hot and cold deserts, rainforests, or other climates. Everyone’s project was very interesting. I got a lot of information from http://www.ucmp.berkeley.edu/exhibits/biomes/index.php. Freshwater biomes consist of lakes, ponds, streams, rivers, and wetlands. Before this project I did not know that freshwater areas actually do contain salt, although it is less than1%. My subject, marine biomes consist of oceans, coral reefs, and estuaries. I mainly focused on coral reefs because they are so interesting. The diversity of life in coral reefs is amazing. Thousands of different organisms live together. Before this project, I did not know that a coral reef is actually a mass of living things, called polyps. After they die a new one grows on the old ones skeleton. This is the way that coral reefs grow, skeletons building up, and a coral reef can grow around one inch per 100 years! Desert biomes are also very interesting. Deserts can be hot or dry. Most people think of deserts as hot, barren, sandy land, but one example of a cold desert is Antarctica. They are also semiarid and coastal deserts. Forest biomes cover about 1/3 of the earth. There are tropical, temperate, and boreal forests. Grassland biomes are another biome people did projects on. There are tropical grasslands, savannas, and temperate grasslands. Temperate means moderate, or not extreme. The last biome is the tundra. There are alpine tundra and arctic tundra. Tundra is the coldest of all biomes. I defiantly learned a lot from this biome project and think that earth science about populations and habitats are very interesting.

Personally, I thought that researching my biome was interesting. I learned a ton of information about the freshwater biome from the research that I did, and I also learned additional information from the presentations that were given in class too. Most of my research was focused on marshes like the everglades in Florida. Some of the animals that live in the everglades are the alligator, crocodile, and over 350 species of birds. I also found the arctic, savanna, and tropical biomes very interesting. In a freshwater biome, particularly in the everglades, about 60 inches of rain fall per year. Overall finding out all of this new information about biomes that I did not fully know about was very eyeopening and interesting.

I was sitting in class one day when my teacher told us we were going to be learning about biodiversity in the different biomes of the world and the creatures and plant life that inhabit them. The only thing is she put a twist on learning the unit. She said instead of her giving us a big lecture on the different biomes and the fauna and flora that inhabit them she told our class of about twenty to choose a biome and make a brochure on that biome.I ended up choosing a deciduous forest and I found it interesting that many of the biomes are classified by how many seasons they have. For example my biome had four seasons Summer,Winter,Fall, and Spring whereas other biomes such as the Tundra only have two seasons Summer and Winter. I also found out from my class mates presenting their own brochures that a rain forest has very poor soil but a deciduous forest has very rich soil I found that very perculiar because one would think that an area with so much life would have very good soil but because of all the rain the nutrients are washed away but in the deciduous forest the ground keeps most of its fertility. A couple other determining factors on the biomes are the temperature the climate and the elevation. I thought the way we learned this unit was very interesting and it probed our thinking and creative abilitys and introduced us to a new way of learning. So instead of learning about envirments that are long gone we could learn about enviornments that interest us.

Learning about the biomes in the world was very interesting, and i learned alot of information. There are several biomes that make up our world. Some are hot and some are cold, and they all are unique.

We were assigned to research one biome and make a brochure advertising it. I thought that this was a great way to learn the information. I researched the freshwater biome. The freshwater biome is home to many organisms such as fish, frogs, and turtles. Freshwater biomes contain little or no salt. After doing our separate research on specific biomes, we got together as a class to share our findings. During this time, we listened to what people had to say, and learned a little about each biome. I thought that this was an effective way of learning the material.
