RainforestConservationProject2013 - 1A-Ranching - 0 views

    How Ranching is Causing Deforestion It is the biggest cause of deforestation in the Amazon rainforest and 80% of the deforested areas in Brazil are used for pasture (Greenpeace). Ranches also use a large number of slave laborers. As the cattle grazes the area, they eat the grass and plants in the area and the soil becomes compacted and is no longer sustainable. The cattle ranchers then need to move to another area, destroying more of the rainforest and creating more unsustainable land causing a vicous cycle that keeps continuing. Rancher use the rainforest because it's a cheap way to raise cattle and then export it to other countries such as the United States. The demand for Brazilian beef has grown recently in the past few years due to control over diseases in Brazil (ex. foot-and-mouth disease), improvements and development of more roads into the forest, and how easy it is to gain title to land (which is to just clearing a part of the forest and placing some cattle there). There is so much ranching occurring in the rainforest due to how much easier it is to own cattle and acquire the land than it is to own crops.A Company Involved in Deforestation McDonald's is actively using the Brazil rainforest for their ranching purposes. It enables them to acquire wealth by burning down the rainforest and then paying ranchers to come in and raise cattle. The ranchers don't have a set minimum wage, as we do in the states, therefore they can be paid much less to work. It also doesn't cost much for them to acquire land. All they have to do is burn down a part of the rainforest and then place cattle on the land, then later they can export the beef back to the United States Ways to Prevent Ranching From Causing Deforestation Don't eat or support places such as McDonald's, KFC, or Burger King. Before you go out to eat, research the restaurant and see whether they have ranches in the rainforest. Donate to an organization or cause that is actively trying to stop ranching in the rain

Rain Forest Threats - 0 views

  •  
    Clear-cut swaths of the Amazon rain forest in Quiandeua, Brazil, are often planted with manioc, or cassava, a shrub grown for its starchy root. Farmers slash-and-burn large parcels of forest every year to create grazing and crop lands, but the forest's nutrient-poor soil often renders the land ill-suited for agriculture, and within a year or two, the farmers move on.

Human activity is driving Earth's 'sixth great extinction event' | Environment | The Gu... - 0 views

  • The review, published in the journal Conservation Biology, highlights destruction and degradation of ecosystems as the main threat. In Australia, agriculture has altered or destroyed half of all woodland and forests. Around 70% of the remaining forest has been damaged by logging. Loss of habitats is behind 80% of threatened species, the report claims.
  • More than 2,500 invasive plant species have colonised Australia and New Zealand, competing for sunlight and nutrients. Many have been introduced by governments, horticulturists and hunters. In addition, the report says, average temperatures in Australia have increased, in line with climate change predictions, forcing some species towards Antarctica and others to higher, cooler ground.

How to Save Tropical Rainforests - Introduction - 0 views

  • Five Basic Steps to Saving Rainforests "TREES" is a concept originally devised for an elementary school audience but serves well as set of principles for saving rainforests and, on a broader scale, ecosystems around the world. Teach others about the importance of the environment and how they can help save rainforests. Restore damaged ecosystems by planting trees on land where forests have been cut down. Encourage people to live in a way that doesn't hurt the environment. Establish parks to protect rainforests and wildlife. Support companies that operate in ways that minimize damage to the environment.

Problems - Loss of Species - 0 views

  • Massive extinctions have occurred five times during the earth's history, the last one was the extinction of the dinosaurs, 65 million years ago. Scientists are calling what is occurring now, the sixth mass extinction. The loss of species is about losing the very web of life on Earth
  • Within the next 30 years as many as half of the species on the earth could die in one of the fastest mass extinctions in the planet's 4.5 billion years history.
  • There is also the loss of the genetic diversity within species, as well as the loss of diversity of different types of ecosystems ,which can contribute to or hasten whole species extinction.

WWF - Pacific Temperate Rainforests - 0 views

  • Threats Intensive commercial logging has destroyed more than 90% of the native forests of this ecoregion. The immense size of the mighty redwood trees, and the beauty of their wood, has made them a target for loggers for more than a century. Even logging in surrounding watersheds can have severe repercussions for redwood groves, since it can cause severe flooding, fires, and sedimentation. The spread of urban areas between Monterey and San Francisco, along with the introduction of exotic plants into these ancient forests, exacerbate the problems. Cruise ships can lead to pollution, as well as disturbing whales and other marine mammals. Other threats include pollution from pulp mills and mines. Introduced beavers are also creating problems for native wildlife. Their damming of small streams is making it difficult for Coho salmon to travel upstream and spawn. Similarly, introduced rats, squirrels, and raccoons have reduced the size of seabird colonies as they prey on eggs and young birds.
