The Amazon River

Extracts from this document...

Introduction

Amazon The Amazon River is the second longest river in world. The headwaters begin high in the soaring Andes Mountains and stretches 6,400 km across the South American continent to the Atlantic Ocean. It discharges between 34 to 121 million liters of water per second, and depositing an average of 3 million tons of sediments near its mouth. The outpouring of water and residue is so vast that the salt content and the color of the Atlantic Ocean are altered for a distance of about 320km from the mouth of the river. Also, unlike many other rivers it��s wide and straight from the headwaters to the mouth. During a new or full moon, a wave front from the ocean sweeps 650km upstream at speeds of 65km/h and this causes waves as high as 5m. Because of its vastness, annual floods, and navigability, the Amazon River is often called the Ocean River. The Amazon River is the largest and wettest tropical plain on Earth with heavy rains. Europeans were not the original keepers of this vast rainforest. The Amazonians are trapped between the old and new customs, and since they have traditions, their technology isn��t as modern as the rest of the worlds��. ...read more.

Throughout this period, the majority of precipitation falls and raises the levels of many rivers and floods nearby forests and villages. Though flooding may be beneficial to the environment, it is a problem for residents who live around flood banks or close to the rivers. As the immense amounts of rain collects into the Amazon Basin, people have adapted by constructing houses on stilts so that it allows water to pass below the it or by building houses on rafts so that the whole house rises during a flood. Flooding may be a benefit to some species. Many plants have adapted to the seasonal flooding as a way to disperse seeds. Sometimes, fruit ripens during the flood season and aquatic animals eat them, helping to disperse seeds in new locations. At times like now, temperatures of the rainforests and surrounding areas are peculiarly warmer than usual. Many plants and animals have adapted to certain temperatures of their habitation. However, when temperatures start to rise, they find it harder to survive in intolerable environments. If the water continues to become warmer, some species may become extinct. How can they live through lingering droughts or floods? Humans are the main causes of these harmful effects. ...read more.

Conclusion

If this continues, the rainforest may never be the same again. The rainforest should be healthy; that is the first priority. It should hold onto the rain and return it to the atmosphere to be recycled; this process is called evaporspiration. Without a healthy base of vegetation, water will run right off into the river. All the species depend on the rainforest and the rainforest depends on it. Insects help pollinate flowers and recycle fallen foliage. While birds and small animals help spread seed to clearings. All of nature relies on each other to outlast. Large-scale developments began in 1980��s and cleared large sections of the rainforest�� s cover. The re-growth is not as diverse as the original over. Though the Brazilian government has strove to make effort and monitor development and protect the natural resources, deforestation continues. For every one person that is illegally destroying the rainforest, hundreds aren��t caught; the monitors are outnumbered. Burning the forest is reducing humidity greatly. Twenty-nine thousand square kilometers per year of deforestation is the size of Connecticut and New Jersey put together. A difficult issue calls for a difficult solution. If our rainforest is further threatened, the high levels of precipitation brought by daily rain, which the rainforest needs, will soon lessen. Damage to the overall system will limit rain immeasurably. Less rain results in more forest fires; something overdone will definitely throw the balance askew. ...read more.

  1. Causes and consequences of deforestation of the Amazon Rainforest.

    Deforestation is also contributing to climatic global change. Fewer trees means less evapotranspiration and therefore less water vapour in the air. This means reduced rainfall, possibly leading to droughts. At the same time, the burning of the forests releases huge amounts of carbon dioxide, one of the main gases causing global warming Groups that been affected by deforestation
