Although the overwhelming devastation of the Permian extinction seemed to play no favorites and whatever survived was the luck of the draw, recent research has demonstrated that even with such a catastrophe, certain life forms were more resilient than others, related to biological “buffers” in their life processes. In marine environments, the warming, anoxia, and acidification would have wiped out species vulnerable to them, and corals were and still are particularly susceptible to those changes. Those conditions wiped out the corals in the Permian extinction, and they are the first ecosystems being devastated today, with similar conditions of . Whether it was the ability to move to safer environs or the ability to buffer chemical changes, the more organisms had a better survival rate than others.
When humans began to raze forests and use the resultant soils to raise crops, they were working their way down through the food chain, no longer harvesting ecosystem detritus but destroying entire ecosystems literally at their roots for short-term human benefit. That practice eventually turned forest ecosystems into deserts. As this essay will survey, that was a rampant problem in all early civilizations. Eventually, humans learned to reach even further back into the ecological horizon as they began burning energy stores that were hundreds of millions of years old; was first and second. They were burned a million times as fast as they were created. In all instances, humans were releasing sunlight energy that had been captured and stored by organisms. In the 20th century, when humans began using nuclear fission, they were going even further back in time and harvesting energy stored via billions of years ago. With each new energy source, humans were harvesting older, more concentrated energy sources, which released far more energy than the previously used source. In each instance, humans plundered the energy source to exhaustion. Humans have not lived in “harmony” with nature since they learned to control fire.
- Analysis of what I have learned introduction.
Here is a brief summary of this essay. Ever since more than three billion years ago and about a billion years after the Sun and Earth formed, organisms have continually invented more effective methods to acquire, preserve, and use energy. after three billion years of evolution and, pound-for-pound, it used energy . The story of life on Earth has been one of , and in turn influencing them. During the eon of complex life that began more than 500 million years ago, there have been many brief for some fortunate species, soon followed by increased energy competition, a relatively stable struggle for energy, and then cleared biomes and set the stage for another golden age by organisms adapted to the new environments. Those newly dominant organisms were often marginal or unremarkable members of their ecosystems before the mass extinction. That pattern has characterized the journey of complex life over the past several hundred million years. among some animals, which provided them with a competitive advantage.

What I learned in Sociology 101 Essay Example for Free
Throughout high school, my English teachers were boring, monotone, and
seemed unenthusiastic about their work. they acted like they were better
than the students were. They approached the class thinking, "I know what
I'm talking about and you don't, so shut up and listen to me." You, on the
other hand, made the class interesting. You kept my attention, which is
often hard to do. You seemed able to relate to us in a friendly way,
rather than as teacher/student. You seemed to approach the class thinking,
"I know what I'm talking about, but you might too, so please listen to what
I have to say and you can add what you want later." This approach is much
better. It causes the students to think. You made the class fun, while
still keeping it a class, not a game. When the class is more fun it causes
the students to become better motivated to do well. This is what most
influenced me during the semester. If it were just another boring old
English class I wouldn't have accomplished anything.
