Why are rainforests important? - 0 views

  • Rainforest in Honduras WHY ARE RAINFORESTS IMPORTANT? Flying over the heart of the Amazon is like flying over an ocean of green: an expanse of trees broken only by rivers. Even more amazing than their size is the role the Amazon and other rainforests around the world play in our everyday lives. While rainforests may seem like a distant concern, these ecosystems are critically important for our well-being.
  • Rainforests are often called the lungs of the planet for their role in absorbing carbon dioxide, a greenhouse gas, and producing oxygen, upon which all animals depend for survival. Rainforests also stabilize climate, house incredible amounts of plants and wildlife, and produce nourishing rainfall all around the planet. Rainforests: help stabilize the world’s climate; provide a home to many plants and animals; maintain the water cycle protect against flood, drought, and erosion; are a source for medicines and foods; support tribal people; and are an interesting place to visit

Rainforest Concern - Why are rainforests important? - 0 views

  • They provide a habitat for plants and animals Tropical rainforests took between 60 and 100 million years to evolve and are believed to be the oldest and most complex land-based ecosystem on earth, containing over 30 million species of plants and animals. That's half of the Earth's wildlife and at least two-thirds of its plant species!
  • contain 1000 trees with up to 300 species.
  • There are many more thousands of rainforest plants and animals species still waiting to be discovered.

  • Without rainforests continually recycling huge quantities of water, feeding the rivers, lakes and irrigation systems, droughts would become more common, potentially leading to widespread famine and disease.
  • Did you know that we also depend on trees to cleanse our atmosphere? They absorb the carbon dioxide that we exhale, and provide the oxygen we need to breathe. When rainforest trees are burnt they release carbon dioxide, which pollutes the atmosphere and contributes to global warming. Deforestation is in fact considered the second major driver of climate change (more than the entire global transport sector), responsible for 18-25% of global annual carbon dioxide emissions.

WWF - Forests, jungles, woods & their trees - 0 views

  • Forests cover 31% of total land area.   The livelihoods of 1.6 billion people depend on forests.   Forests provide a home to more than 300 million people worldwide.   The total global trade in forest products was valued at around $379 billion in 2005.   Forests are home to 80% of terrestrial biodiversity.
  • In this high-tech world of metal and plastic, it's easy to forget that many things are still made with good, old-fashioned wood. Countries with lots of forest stand to benefit from the lucrative timber trade, but at what cost to their ecological footprint? Here are five major timber exporters, and who is buying their wood. © WWF / GOOD / SectionDesign The Global Timber Trade, Who's Buying, Who's Selling?

The five most forest-rich countries are the Russian Federation, Brazil, Canada, the USA and China, and they account for more than half of the total forest area. Ten countries or areas have no forest at all and an additional 54 have forest on less than 10% of their total land area.

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.

Rainforest Facts - 0 views

  • Often described as the Earth’s lungs, only in reverse, the tropical rainforests
  • What’s truly amazing, however, is that while the tropical rainforests cover just 2% of the Earth's land surface, they are home to two-thirds of all the living species on the planet. Additionally, "nearly half the medicinal compounds we use every day come from plants endemic to the tropical rainforest." If a cure for cancer or AIDS is to be found, it’ll almost certainly come from the tropical rainforests.
  • The Primary Source, writes that "tropical rainforests are the Earth’s oldest continuous ecosystems.

  • The largest rainforests are found in the Amazon Basin of South America, in Western African countries that skirt the equator, as well as South Pacific countries such as Indonesia and the Philippines.

The Effects of Destroying the Tropical Rainforests - 0 views

  • When the trees are cut down it takes away the habitat of the plants and animals. It also reduces the space for the indigenous people who have lived there for thousands of years.
  • This way of life has died out with contact from incomers.
  • Some native groups suffered greatly from diseases which they had no resistance to.
  • ...3 more annotations...
  • Deforestation has led to the loss of thousands of species of insects, animals and plants. It means that important chemicals that could be used for medical purposes have not been found and will be lost.
  • Without the branches and leaves to break its fall, heavy tropical storms can quickly wash the soil from even an gentle slope.
  • The climate of the area becomes drier with the loss of the vegetation which acts as a "sponge" to hold on to the moisture. Having less cloud cover means the increase in temperatures. Both the burning of the trees and their reduced number increases the concentration of carbon dioxide. The extra carbon dioxide is believed to contribute to global warming, which in turn is blamed for the rise in sea level.

WWF - Amazon - World's largest tropical rain forest and river basin - 0 views

  • The landscape contains:One in ten known species on Earth1.4 billion acres of dense forests, half of the planet’s remaining tropical forests4,100 miles of winding rivers
  • Basin
  • 2.6 million square miles, about 40 percent of South America, in the Amazon
  • ...6 more annotations...
  • There is a clear link between the health of the Amazon and the health of the planet. The rain forests, which contain 90-140 billion metric tons of carbon, help stabilize local and global climate.Unfortunately, deforestation may release significant amounts of this carbon, which could have catastrophic consequences around the world.
  • Amazon, a place two-thirds the size of the U.S.,
  • WWF has been working in the Amazon for 40 years
  • construction of roads and dams, and extractive activities including illegal logging and climate change are the biggest drivers of deforestation and river degradation. At current deforestation rates, 55% of the Amazon's rainforests could be gone by 2030
  • 40,000 plant species, 3,000 freshwater fish species and more than 370 reptile species exist in the Amazon. It is one of the world’s last refuges for jaguars, harpy eagles and pink dolphins and home to many birds and butterflies. Thousands of tree-dwelling species including southern two-toed sloths, pygmy marmosets, saddleback and emperor tamarins and Goeldi’s monkeys are found here too.
  • More than 30 million people from 350 indigenous and ethnic groups live in the Amazon and depend on nature for agriculture, clothing and traditional medicines. Most live in large urban centers, but all residents rely on the Amazon’s natural bounty for food, shelter and livelihoods.
