Catherine Medrano Research Question #2 14 March 2013 Future Plant and Animal Diversity in Tropical Rainforests Within the last 50 years deforestation has taken 17% of the Amazon’s land area and imposes a major impact on plant and animal species (WorldWildLife.Org/threats/deforestation). Frustrations over the biodiversity in the tropics have created a sense of turmoil in which scientists are concerned with political judgment. Political officials have protested the idea of the future loss of biodiversity to be inadequate and extremely low. Evidence has founded that with the increased deforestation and population rates the human race is at terrible risk of not only loss of resources but of habitat loss due to extinction rates (Bradshaw et al., 2009). These findings can conclude that with increased exposure to deforestation plants and animals are limited in habitat reformation and thus cause problematic extinction rates for the future.
Tropical rainforests are rapidly disappearing in a way that will greatly have an impact on planet earth. Since 1950, half of all tropical rainforests are gone because deforestation, mining and many other things are taking nature away from us. In a few decades, it has been estimated that the rest will be gone if we measures are not taken soon. The WWF (World Life Federation) oversees this ecological threat. They are working to save nature by helping people live in harmony with nature.
When they become overpopulated, the whole eco-system can be drastically affected. Native food sources can be depleted very quickly which can result in extinction. For example, the loss of cougars and wolves in much of the U.S has led to many species becoming over populated. Without the whitetail deer being hunted, there would be major crop damage and many more car versus deer accidents. Overpopulation often leads to disease and malnutrition.
She elaborates on the issue of spraying chemicals and if it is increasing or decreasing the progress in the world. Carson’s article states that we are hurting ourselves more than we benefit ourselves from the spraying of harmful chemicals, and that we endanger our environment with these chemicals. In order to persuade the progressive intellectuals of this argument, Carson provides data to show the actual harm the pollution from the chemicals is causing, and provokes fear in her audience. In order to make her argument appear reasonable, Rachel Carson uses scientific observation to demonstrate how chemicals are the cause of killing pests. Carson provides rational examples to show the harm that pollution is causing to the earth and pests.
Introduction: The reasons for this study it to show the effect of acid rain on plants more specifically sunflower, radish, and clovers. The hypothesis is that the plant would ether die or be severely damaged due to constant exposure of the acid rain. With that in mind there is already historical evidence showing how exposure to Acid rain has caused damage in forests. One example is the Great Smoky Mountains national parks were acid rain has damaged and or kill an entire section of the forest. The reason to do this experiment is to show awareness towards this growing environments problem that is killing many important environments and ecosystems.
Therefore, deforestation sabotages habitat loss, insufficient food for the jaguars and other carnivores. These are the causes of which poachers try to “control” jaguar population by killing them. But they do not only kill them but find great business in selling their skin and tooth which caused the illegal trade as a habit. For this reason, the jaguars have been of great importance to the environment lovers
For thousounds of years, many Indians have lived in the Amazon rainforest. These natives relied on their natural surroundings for their livelihood as well as for their food.They grew maize and wild rice,ate fruits, vegetables, nuts, and their oils, and caught fish from the rivers. Slowly,however,these people have disappeared.They have been wiped out by constant fighting among the various tribes and by diseases brought in by foreign traders and settlers. Now the population of the Amazonian Indians has shrunk to arround one million people. The Amazon, the main river that flows through the Amazon rainforest,is a place of wonder because it is inhabited by exotic animals that live in and around it.
Also, Africans lost the right to work for themselves and were forced by the Europeans to labor in mines or collect rubber and other plants from the jungle. If the Africans were unable to fulfill the demands of the European soldiers, they were punished severely; many had their hands or ears cut off and some were killed. Another negative effect was that many Africans were brought to the Americas to
Illegal drug production involve indiscriminate use of pesticides, fertilizers and corrective measures by those cultivating the crops, these actions alter the physiochemical properties of the soil. On top of that, we must consider the practice of burning rain forest to gain land for crops, and reductions in the flora and micro fauna in the soil such as symbiotic bacteria, larvae, etc. Furthermore, the emissions from refineries used to process the illicit crops increase the concentrations of CO2 and other greenhouses gases in the atmosphere. Based on this, we can say that it takes a very long time to recover from it and repair the damages caused by these processes. Consequently, we have
Dangers of Invasive Species Invasive species should have laws against them; they are a major threat because they can destroy ecosystems and threaten other animals/plants and even humans. What are Invasive Species? Invasive species are organisms introduced into a non-native ecosystem and which cause, or are likely to cause harm to the economy, environment or human health (“Laws”, para. 12). If one thing that should be in your mind while you read this is the Florida Everglades and our great lakes.
