The situation can quickly turn into a global crisis. If it becomes less plankton, it means that fish and turtles will have nothing to eat, and if they begin to disappear, then the number of predators such as sharks and whales, also will be reduced. And it will be an echo of humanity for their actions, because less sea food will be available to
All of the dry weather led to this severe water shortage which caused the drought. Even the little rainfall that came, was sucked up by the soil, leaving the people helpless and out of luck. When there was no rain, there was not enough water for the crops that were trying to grow, or the people who were thirsty. However, some farmers realized that deep under the soil, there was water left behind from the last ice age that occurred millions of years back. The water that they found underground, was used to water plants, that still did not end up surviving.
The most basic dilemma in this situation is that there isn’t a farm to go back to. “They’d take July off, the two of them, go back to the farm, but it was a vain dream… There would be nothing to eat there. The cover was gone and no crops planted. (Page 140)” When Lyddie left for Lowell, no one was left to maintain the farm, only the Stevenses, who agreed to monitor the farm, but nothing more. With no one to tend to it, the farm is obviously not fertile.
Also, it makes sense that one result of this would be that the protozoans disappear, or even die. In the LJOC ecosystem, the relationship between protozoans and bacteria is a predator and prey relationship. This means that protozoans are the consumers, eating bacteria—the producers—for food. If their aquatic habitat has a higher pH than 7, then the effect disinfectants have on bacteria will likely happen; the bacteria will die. This means that the protozoans would have a shrinking food source, which is an important limiting factor that has quite a considerable effect on the carrying capacity of the population of protozoans.
Also, even if they tried to renew their resources, the demand rate was increasing so much, they would have never been able to save the ecosystem. “While the hauhau tree did not become extinct in Polynesian times, its numbers declined drastically until there weren’t enough left to make ropes from” as stated in Easter’s End. Another similarity was that most of the species in these environments had depended on these trees and plants for survival and shelter. Since the resources were being used at such an alarming rate the animals would become extinct over time because the loss of all their sources of food and shelter. Easter’s End states “The destruction of the island’s animals was as extreme as that of the forest: without exception, every species of native land bird became extinct.” The final similarity I found was that both places were very rich,fertile and filled with abundance amounts of resources.
Our Earth being both a place of sustenance and shelter is the only place that humans can survive as of right now. Although the discovery of survival might be possible in other planets in the future, the planet of our home is decomposing and transforming into a planet that no organism can survive. The natural order of things in an ecosystem is solely dependent on whether we create a disturbance that can penetrate earth’s shields. In “The World’s Hot Spot” by Thomas L. Friedman, an opinion columnist for the New York Times, suggests that we take a look at nature before it gets extreme and save our personal issues for later. In the article, the use of tone, diction, evidence, and vivid imagery were integrated to clearly portray the current situation of what mother nature is causing as consequences of the problems we create and our least concern in finding a solution.
Relationships between countries will be broken apart over disputes for water. Citizens may revolt and attempt to overthrow the government as they would want to gain water by their own methods. Humanity needs to think about future generations and if whether or not they are going to have enough water to live. According to the article “Population Control”, animals will be hunted into extinction if the population keeps growing. Animals are essential to the survival of this
Martha is a symbol of the threat of the extinction, and the need for conservation. Even a bird whose species numbered in the billions could go extinct in a short period of time. Greenberg uses a species as an example, whose extinction can be directly correlated to human activities. I feel that this relates to the sentiment expressed in Dr.Sanford’s lecture because it speaks to the need for humans taking responsibility for our actions. Society today does not have the same excuse of ignorance as our ancestors did.
