Water Turns to Blood --- JoAnne Burkholder --- Limnologist ---

After read the novel "And The Waters Turned to Blood", I can describe how JoAnne became a limnolgist. Limnologist is the scientific study of the life and phenomena of fresh water, especially lakes and ponds.

The first reason is her childhood experience. She was raised well by her father who had all but grown up in the woods, hunting, fishing, and also trapping. He taught JoAnne about a lot of things about live in the open air and made her love it. So, from the very beginning, JoAnne had already love to live in the open air, observing water, animals, and a lot of other thing at the forest.

The second reason is her experience as a junior in high school. The concept that every lake had its own natural life cycle, beginning as a cold, clean body of water that supported a variety of healthy plant and animal life, and moving through stages toward becoming a shallow, warm marsh that hosted only the lowest forms of life was really captured her interest. By that, she decided that she was going to be involved in "water science".

The third reason is her proffesor support and recommendation. Actually, she couldn't go to get the higher education because financial problem. She worked at a drugstore until someday she was hired as an assistant in a limnology research at Iowa state. She showed that she could hike in the woods, ford streams, and camp with the best group of other scientist there. At the end, her limnology professor recommended her to North Carolina State. By his support, JoAnne flew to North Carolina and started her career as a limnologist.

Science Poem

Queen of the Silent Spring

Rachel Louise Carson
bright, considerate, & curious
born in Springdale, Pennsylvania
care about environment, especially the usage of pesticides
love the environment and nature
creative, brave, & caring
write Silent Spring
feared if the environment damaged or unresponsibly used
wanted if the environment beauty is everlasting

Rachel Carson, Environmentalist

Rachel Louise Carson (May 27, 1907 – April 14, 1964) was an American marine biologist and nature writer whose writings are credited with advancing the global environmental movement.

Carson started her career as a biologist in the U.S. Bureau of Fisheries, and became a full-time nature writer in the 1950s. Her widely praised 1951 bestseller The Sea Around Us won her financial security and recognition as a gifted writer. Her next book, The Edge of the Sea, and the republished version of her first book, Under the Sea Wind, were also bestsellers. Together, her sea trilogy explores the whole of ocean life, from the shores to the surface to the deep sea.

In the late 1950s, Carson turned her attention to conservation and the environmental problems caused by synthetic pesticides. The result was Silent Spring (1962), which brought environmental concerns to an unprecedented portion of the American public. Silent Spring spurred a reversal in national pesticide policy—leading to a nationwide ban on DDT and other pesticides—and the grassroots environmental movement the book inspired led to the creation of the Environmental Protection Agency. Carson was posthumously awarded the Presidential Medal of Freedom by Jimmy Carter.

                                                                                                                                                          

The Bears are hungry in the Rockies

http://www.enn.com/wildlife/article/41831

This year, bears are wrestling with very challenging conditions. One of them is lack of food, a shortage of berries and other foods that bears normally rely before hibernation has sent into conflicts with humans in the Rocky Mountain West. This lack of food caused bears that used to live in the mountain come into the cities. We can found bears are foraging in garbage cans, such as in; golf courses, cities centers, and many others place. And in the late spring snows, which blanketed the high country, pushed bears to lower elevations earlier, delayed or even destroyed the crop of fruit-producing shrubs bears favor, such as huckleberries and hawthorns. Conflicts between wildlife and humans almost always center on food. When supplies of nourishment are low in the mountains, bears move closer to the valleys, where people live and livestock is conveniently located.

Advantages of Maps in Environment Science

Maps are very important in studying science, especially environment science. The first reason why maps are important is we can know more about the world, we know more about where we live now. We need that information because each environment that spread among the world are different. For instant, environment in  Northern Africa is totally different with environment in Indonesia (South East Asia). Africa has desert and Indonesia has tropical jungle. And because of the difference, the animals and type of plants that can grow are different too. In desert we can find palm trees and camels. In tropical jungle we can find huge trees and also "orang utan" that similar with monkeys.

The second reason why maps are important because by map, we can know what does a country rich of or lack of. Maybe some country is rich of humans population, in other word it means that one country had a lot of humans there. Maybe some country is lack of humans population, it means that the country is need more human to develop a better country.

There are also so many kind of maps in this world. 2 of them are physical map and population map. Physical map is type of map that supplies our knowledge with data about the earth. From physical map we can know where is China, and also where is Argentina, and others.

This is a physical map of the earth

And the other one is population map. Population map is type of map that overview about the population density in various parts of the world. For instant, there is map called U.S. Population map. By the name, it overview the population density in United States of America.

This is a population map of the United States of America

Characteristics of Chaos

1.  Butterfly Effect

The butterfly effect is a metaphor that encapsulates the concept of sensitive dependence on initial conditions in chaos theory; namely that small differences in the initial condition of a dynamical system may produce large variations in the long term behavior of the system. Although this may appear to be an esoteric and unusual behavior, it is exhibited by very simple systems: for example, a ball placed at the crest of a hill might roll into any of several valleys depending on slight differences in initial position. The butterfly effect is a common trope in fiction when presenting scenarios involving time travel and with "what if" cases where one storyline diverges at the moment of a seemingly minor event resulting in two significantly different outcomes.



2. Unpredictable

Chaotic system is totally unpredictable. We can prove it by doing the Chaos Game Dots. We can't know what number will be shown by the dice in the next step and so on.

3. Instability

Chaos also has a characteristic called instability. It means that chaos is easily change. Take for example if we build a tower from a deck of card. It won't be 100 % stable. It can be ruined easily with a simple softly wind.





My Goals

By taking this class, I want to know a lot about environment science. I want to know about the ecosystem and circumstances around me, so I can more understand about our nature, our earth, how to save it, how to manage it, and how to make a good living in harmony with the nature. I think a good environment will support and give a lot of benefits to our life.
Our life is very depents on the natural resources around us.  If there are a lot of people have knowledge about the environtent around they live, there will be more resorurces we can save too. At the end we can save the world from it's damage. I wish there also more sickness we can handle, so  there will be more and more peolple live healthy and happily. But the most of all,  sure I want to pass this class well.
