Canopy: rainforests have a canopy, which is the layer of branches and leaves formed by closely spaced rainforest trees. These have been enormously important decades for tropical peoples and environments. With Earth Day approaching it is appropriate to take another look at conservation efforts in the world's tropical rainforests, which today are disappearing from the face of the globe. The warmth of the rain forest allows cold-blooded invertebrates to exceed their usual size. Bacteria use these as a source of hydrogen.

Found on poorer soils consisting rocks such as rhyolite, trachyte and slates in the Tweed (Wollumbin) Volcano region, and on the more fertile eutrophic rocks in southern cooler regions, Warm Temperate Rainforest requires rainfall over 1300mm per year ref.: http://nickel-titanium.com/lib/national-geographic-readers-ants. As forests are cut down, many species are doomed to extinction. Most rainforest species can survive only in their natural habitat. As their habitat is destroyed, many well-known rainforest species are threatened with extinction, including orangutans, rhinos, tigers, gorillas, elephants, as well as many birds, monkeys, reptiles, and amphibians , e.g. http://nickel-titanium.com/lib/the-national-geographic-magazine-volume-92-number-4-october-1947.

Just as reductionist thought leads to a mind-body split, it also leads to thinking of humans as separate from the earth and other living beings. In contrast, deep ecology is a holistic worldview, which values all life forms and their multivariate interrelationships. Whereas the reductionist mind-body, or human-earth split results in destruction of the environment to the detriment of humans as well as other living beings, the holistic view of deep ecology promotes healing of the planet, including an integrated human consciousness http://nickel-titanium.com/lib/tropical-rain-forests-an-ecological-and-biogeographical-comparison.

Lowland primary forest, often characterized by more than five forest tier levels, is usually taller and more diverse than montane forest. It has a greater diversity of fruiting trees; hence more animals specially adapted to feed on their fruits and more large mammals ref.: http://schoolbustobaja.com/?freebooks/the-national-geographic-magazine-vol-180-october-1991. They estimate that the total lowland humid and swamp forest area for Africa is 1 998 290 km2, of which 89.3% is in Central Africa, 6.0% in West Africa, 2.2% in Madagascar and 2.4% in Eastern Africa. In terms of countries, the Democratic Republic of Congo (DRC) is the forest giant, accounting for 53.6% of Africa's lowland rainforest area, followed by Gabon (11.2%), the Republic of Congo (10.4%) and Cameroon (10.0%) http://vprsanonymous.com/?freebooks/national-geographic-magazine-august-1974.

This is roughly located between the Tropic of Cancer and the Tropic of Capricorn, 22° degrees north and south of the equator. These rainforests once covered 14% of the earth's surface, but massive exploitation has more than halved that amount. It has been estimated that if the present rate of consumption were to continue, within 40 years the last remaining tropical rainforests could have gone ref.: http://istarestudi.com/?books/national-geographic-magazine-january-1986-vol-169-no-1. Australia’s Tropical Rainforests cover approximately 900,000 square hectares and are internationally recognised as being one of the most ecologically fascinating natural areas in the world, as one of few remaining truly pristine tropical rainforest places on the planet , source: http://nickel-titanium.com/lib/rain-forests-insiders. Antarctica, population and sustainable development, and women in conservation. These activities enable lUCN and its members to develop sound policies and programmes for the conservation of biological diversity and sustainable development of natural "All our knowledge must be deployed to produce programmes that will reconcile the needs of the people who live in the forests with those of industrialists and politicians living around their margins, and those of the people in the world at large who can see that the tropical rain forests contain some of the world's greatest treasures and are an integral part of both its health and glory." Description: An understanding of the characteristics and the ecology of soils, particularly those of forest ecosystems in the humid tropics, is central to the development of sustainable forest management systems. The present book examines the contribution that forest soil science and forest ecology can make to sustainable land use in the humid tropics http://agiosioanniskalyvitis.gr/books/life-magazine-april-30-1945. Some tree species also suffer reduced threats of vine colonization because the symbiotic ants that they harbor and feed keep their host tree free of parasites, including structural parasites such as lianas (Janzen 1969) http://go-science.ru/?lib/rain-forest.
