He included three species under the genus Lemur: Lemur tardigradus the red slender lorisnow known as Loris tardigradusLemur catta the ring-tailed lemurand Lemur volans the Philippine colugonow known as Cynocephalus volans. Evolution of lemurs Lemurs are primates belonging to the suborder Strepsirrhini. Like other strepsirrhine primatessuch as lorisespottosand galagosthey share ancestral or plesiomorphic traits with early primates.
The Disappearing Rainforests We are losing Earth's greatest biological treasures just as we are beginning to appreciate their true value. One and one-half acres of rainforest are lost every second with tragic consequences for both developing and industrial countries.
Rainforests are being destroyed because the value of rainforest land is perceived as only the value of its timber by short-sighted governments, multi-national logging companies, and land owners. Nearly half of the world's species of plants, animals and microorganisms will be destroyed or severely threatened over the next quarter century due to rainforest deforestation.
Experts estimates that we are losing plant, animal and insect species every single day due to rainforest deforestation. That equates to 50, species a year. As the rainforest species disappear, so do many possible cures for life-threatening diseases.
Currently, prescription drugs sold worldwide come from plant-derived sources. Most rainforests are cleared by chainsaws, bulldozers and fires for its timber value and then are followed by farming and ranching operations, even by world giants like Mitsubishi Corporation, Georgia Pacific, Texaco and Unocal.
There were an estimated ten million Indians living in the Amazonian Rainforest five centuries ago. Today there are less thanIn Brazil alone, European colonists have destroyed more than 90 indigenous tribes since the 's. With them have gone centuries of accumulated knowledge of the medicinal value of rainforest species.
As their homelands continue to be destroyed by deforestation, rainforest peoples are also disappearing. Most medicine men and shamans remaining in the Rainforests today are 70 years old or more. Each time a rainforest medicine man dies, it is as if a library has burned down.
When a medicine man dies without passing his arts on to the next generation, the tribe and the world loses thousands of years of irreplaceable knowledge about medicinal plants.
If Amazonia were a country, it would be the ninth largest in the world. The Amazon Rainforest has been described as the "Lungs of our Planet" because it provides the essential environmental world service of continuously recycling carbon dioxide into oxygen.
More than 20 percent of the world oxygen is produced in the Amazon Rainforest. More than half of the world's estimated 10 million species of plants, animals and insects live in the tropical rainforests.
One-fifth of the world's fresh water is in the Amazon Basin. Its bountiful gifts to the world include fruits like avocados, coconuts, figs, oranges, lemons, grapefruit, bananas, guavas, pineapples, mangos and tomatoes; vegetables including corn, potatoes, rice, winter squash and yams; spices like black pepper, cayenne, chocolate, cinnamon, cloves, ginger, sugar cane, tumeric, coffee and vanilla and nuts including Brazil nuts and cashews.
At least fruits are found in the rainforests; of these only are now in use in the Western World. The Indians of the rainforest use over 2, Rainforest plants are rich in secondary metabolites, particularly alkaloids. Biochemists believe alkaloids protect plants from disease and insect attacks.
Many alkaloids from higher plants have proven to be of medicinal value and benefit. Currently, prescription drugs currently sold worldwide come from plant-derived sources.
National Cancer Institute has identified plants that are active against cancer cells. Twenty-five percent of the active ingredients in today's cancer-fighting drugs come from organisms found only in the rainforest. Vincristine, extracted from the rainforest plant, periwinkleis one of the world's most powerful anticancer drugs.
It has dramatically increased the survival rate for acute childhood leukemia since its discovery. Inthere were no U. Today, over pharmaceutical companies and several branches of the US government, including giants like Merck and The National Cancer Institute, are engaged in plant research projects for possible drugs and cures for viruses, infections, cancer, and even AIDS.
Rainforest Action Experts agree that by leaving the rainforests intact and harvesting it's many nuts, fruits, oil-producing plants, and medicinal plants, the rainforest has more economic value than if they were cut down to make grazing land for cattle or for timber.
If managed properly, the rainforest can provide the world's need for these natural resources on a perpetual basis. Promoting the use of these sustainable and renewable sources could stop the destruction of the rainforests.
By creating a new source of income harvesting the medicinal plants, fruits nuts, oil and other sustainable resources, the rainforests is be more valuable alive than cut and burned. Sufficient demand of sustainable and ecologically harvested rainforest products is necessary for preservation efforts to succeed.
Purchasing sustainable rainforest products can effect positive change by creating a market for these products while supporting the native people's economy and provides the economic solution and alternative to cutting the forest just for the value of its timber.
It is impossible to capture on film, to describe in words, or to explain to those who have never had the awe-inspiring experience of standing in the heart of a primary rainforest.Chapter Conservation of Biodiversity. Madagascar is considered a biodiversity "hotspot" because A.
it originated as a volcanic island.
B. it has lost nearly all of its native species to extinction. C. it contains an unusually high concentration of species. Oct 27, · We are posting this information to clear up the considerable confusion about the Weston A. Price Foundation dietary principles and the “paleo diet.”.
