Blog #8: Your choice: Talk about something you learned or ask a question about something that is confusing you.
Something I learned about recently is about the food pyramid, which I had to research in my previous blog. I thought I knew about the food pyramid before, but I learned a lot of new things about it. A few years ago, there was an old food pyramid, which showed that proteins was the most important part of the pyramid. This led to obesity in many people, because everyone thought that they could eat a lot of proteins and carbs, like bread. However, no one really understood the food pyrimid serving sizes, so they ate according to the pictures, which weren't always accurate. After all, they were just pictures, and the important thing was learning what to eat, and how much to eat it. So, in 2005 a new food pyramid was created, making the fruit and vegetable part of the pyramid more important to our health. It showed better ways to eat healthy.

Blog #7: Compare and contrast two biomes. Describe them in detail; include pictures of plants and animals you are likely to see.
The Freshwater Biome accounts for one fifth of Earth and provides half of the drinking water, one third of the water used for irrigation, and nearly ninety percent of the world's bathwater. The biome consists of inland lakes, streams, brooks, creeks, rivers, ditches, sloughs, gutters, puddles and canals. Leeches and catfish are a few of the many animals that the Freshwater Biome supports.

The Marine Biome are consisted of marine regions, coral reefs, estuaries, and oceans. This is similar to Freshwater Biomes because they both contain bodies of water, but Marine Biomes cover more of Earth's area, about 3/4 of Earth's surface, opposed to Freshwater Biomes which cover only 1/5 of Earth's area.

Blog #6 Which level of the food pyramid is the most important? Support your answer.
In my opinion, fruits and vegetables are the most important level of the food pyramid. Although people can argue that proteins is the most important, fruits and vegetables can't make you overweight or unhealthy if you eat more than the recommended portion. When the new food pyramid wasn't created yet, people were going by the old food pyramid, which had proteins as the biggest and most important part of the food pyramid. That led many Americans to obesity, which is why the new food pyramid was created: to help people better understand how many servings of each level they should be eating. Fruits and vegetables are most important because they contain carotenes, which enhance our immune systems and helps against diseases. Fruits and vegetables also provide fiber, nutrients, minerals and vitamins, such as Vitamin A, which is good for eyesight and growth, and Vitamin C, which is good for protection against viruses and bacteria and healing wounds.

There have been 5 major extinction events throughout history, are humans impacting the 6th? Why or why not?
I do believe that humans are impacting extinction. Many animals are constantly in danger of being extinct, because of many reasons which include hunting animals for food, and destroying natural habitats. One website even says that a biodiversity expert has warned us that "humans are driving animals and plants to extinction faster than new species can evolve." If this is true, wildlife is in anger, and humans are the cause. Also, it is becoming increasingly difficult for animals to survive in the climate changes and habitat loss. Unfortunately, almost 17,300 species are considered under threat and a lot would have to be done to stop these species from future extinction.
