Aquatic Invertebrates: Adaptations and Feeding Guilds INTRODUCTION Global warming and human's authoritative influence on the environment such as deforestation, pollution etc. are taking a bad toll on the diversity of the ecosystem. Global warming which has brought about increase in the temperatures is disturbing the natural cycle of the ecosystem. This has brought upon an increased droughts throughout the world. The droughts and increased heat has had negative impacts on local aquatic invertebrates.
According to CBC News World, “The storm hit Haiti's rural western tip hard, flooding the refugee-camp homes of quake survivors.” (2010). The storm was actually downgraded from hurricane to tropical storm but still caused massive flooding with the vast amount of rain and mudslides that were rampant. The country also has a long history of earthquakes dating back to 1564. The most recent in this list is the 2010 earthquake close to Port-Au-Prince. The nation is located in a region seismic activity due to the movement of the Caribbean tectonic plate, which is compared with which a finger shoving away against two larger plates, the North American and South American.
Since their is a loss of trees when it rains, their is nothing to stop the rain, and so it quickly moves down hill and affects the soil since the nutrients are all being washed down, and it will be faster to cause floods. This issue is causing Haiti to be hit by storms harder then they should. Like the tropical storm of Jeanne, that hit the north, and the four storms that hit in between August, and September. The affects of these storms could have easily been reduced if the forests were still there. Another big effect of deforestation is the fact that it causes soil erosion.
The environmental effects that a hurricane can have on an area can be catastrophic. Massive areas woodland can be destroyed and this is not only important for the wellbeing of the environment but also for the habitats that live in wooded areas. Animals can either be killed by hurricanes or indirectly affected by their homes being destroyed or their food supplies disappearing. Endangered species can also be affected like when Hurricane Hugo struck in 1989, half the population of Puerto Rican parrots disappeared. Erosion is also another key factor that can affect the environment.
The aftermath of this disaster could have been prevented if the government would have designed levees that were strong and high enough in case an event was to occur like Hurricane Katrina. New Orleans, being a hurricane prone part of this country, should not have been neglected in that manner. The documentary shows aspects of the theme of politics and class. This is shown through this film because it shows how the failure of the government affects the people. You can also take the route and correlate low class people were neglected, which cost many lives and peoples’ homes.
Firstly, the Everglades are an important ecosystem which reduces flooding and replenish aquifers but human actions are having a huge impact on the landscape. The rapid urban and agricultural development in the area has decreased the size of the wetlands dramatically which affects the organisms found there. This is especially important as it is home to several endangered species. Not only that, but invasive species that threaten existing wildlife by preying on or competing with them. According to Everglades.org, they’ve “contributed to nearly 70 percent of extinctions in the United States” and are the “primary cause of species endangerment.” The water itself is a major cause of decline to the area, firstly because of poor water management leading to water levels being too low or too high at the wrong times has caused a decline in many species.
Bobby Kmetz Oct 21, 2010 Research Report #1Topic In the world today there are many things that are affecting are environment and a lot of those things have to do with effecting the land and soil around us that we use every day to grow plants on and use to raise livestock on. With all the damaging things that are happening to the worlds soil that we all know of such as erosion and irrigation of lands one type of soil degradation that is just as serious as all the others is overgrazing. Overgrazing can degrade soil because of the way it is treated by the animals and not maintained by the land owners. In the book Essential environments it briefly talks about what different activities have effect on the soils. It talks about how even though
Secondary effects include respiration problems from the plumes of smoke, land slides from soil erosion, and economic losses. As the fires burn large plumes of smoke begin to saturate the air and make the quality of air very poor for breathing. According to (usgs.gov) over 70% of people were affected by respiratory problems from poor air quality in and around the San Diego area during the 2007 wildfires. Another secondary impact of wildfires is soil erosion. Soil erosion occurs when the land is depleted of valuable nutrients making it susceptible to landslides and mudslides in the wet
Zephyr Mauibem Mr. Dendi, Mrs. Napai History, English 9 November 2012 Hurricane Katrina Imagine what it would be like if your home, your belongings, even loved ones were gone. This is what Hurricane Katrina was like for citizens in the Gulf of Mexico area. States like Mississippi, Louisiana, Alabama, and Florida were greatly affected. Hurricane Katrina was a turning point in history because it affected natural disaster safety plans. Katrina also caused financial problems, and changed the way people viewed natural disasters.
The farmers had money to plant new crops, and within a few years the situation in the Great Plains was back to normal. The farmers were paid to plant and grow trees around their field, and used many new soil conservation methods and farming techniques that helped prevent dust bowls in the future 1950s drought and the 1987-1989 drought. Even though the 1987-1989 did cause a lot of damage and negative economical impact, it was not because of dust storms, but because of forest fires, and as states the ncdc.noaa.gov website because of ‘‘losses in energy, water, ecosystems and agriculture.'' It also states that ‘‘the total cost of the three-year drought was estimated at $39 billion.'' this is a great number compared to the expenses caused by the dust bowl which were according to the drought.unl.edu site only one billion US dollars.
