Aerial roots wend their way down past tropical trunks, tree ferns and moss-covered prop roots to an understorey of ferns and seedlings. The jungle is lush, humid and thick with mosquitoes. It is also as cosmopolitan as London’s Heathrow airport. This forest on Big Island features mango trees from India (Mangifera indica); Cecropia obtusifolia, a tree with huge star-shaped leaves from Mexico, Central America and Colombia; rose apples (Syzygium jambos) from southeast Asia; tasty strawberry guava (Psidium

broadly defined as “forest conversion and different types of degradation that reduce forest quality” (Sven, 2000). The Food and Agriculture Organisation (FAO) provides a narrow definition: “depletion of tree crown cover to less than 10% as the deforestation” (FAO, 1993: 10). Forests play a significant role in humanity’s life. According to the World Rainforest Movement (1998), 25% of medicines come from the forests. Moreover, over the past 8000 years, about 5000 square miles of forest has been cut down

of Guyana. These natural resources are very important in to the country’s economy. The lands have much resource also found in the vegetation and the forests. The plants and trees are historical for their abnormal size and density. Guyana has an excellent lumber industry; they sell some of the finest Greenheart, Walaba, and Mora. Guyana’s forest is home to a large variety of wildlife ranging from deer to antler and several

elimination of trees and other plants from forest areas more quickly than they can be replanted or rejuvenated naturally. Urban sprawl is the spreading of urban and suburban areas into undeveloped lands. “(Turk, 2011) Marcus Colchester states that, "Deforestation, in other words, is an expression of social injustice.” The consumption of deforestation happens for many reasons and is quite intricate. They also vary from region to region. Our text states, “Tropical forest

Hot and wet areas with broadleaved evergreen forest * Where: Within 5°N and S of the equator * Climate, limiting factors: High rainfall(2000-5000 mm yr-1), high temperatures( 26-28°) and high insolation, P>E rain washes nutrients out of the soil, so nutrients may limit plant growth * Structure: amazingly high levels of biodiversity: plants compete for light thus growing tall to absorb it, so there is a multi-storey profile to the forests called stratification. Many niches and habitat

including wildlife, fisheries and forests. It also helps provide for basic human needs such as food, shelter and medicine. 3. Biome is a very large area on the earth’s surface with animals and plants adapting to their environment. Biomes are often defined by abiotic factors such as climate, geology, soils and vegetation. The nine Biomes are described in the Hall are Tropical Forests, Tropical Grassland and Savannas, Deserts, Island, Tundra, Temperate and Boreal Forests, Oceans, Freashwater Wetland

locations are South America, Central Africa and South-East Asia. Each region is facing varying degrees of serious deforestation. The result being widespread loss of humid tropical forest “Between 1990 and 1997, 5.8 ± 1.4 million hectares of humid tropical forest were lost each year, with a further 2.3 ± 0.7 million hectares of forest visibly degraded.” (Achard et al. 2002) The heart of the problem lies beneath a tangled mess of socio-economic growth resulting in massive deforestation chiefly for the land

Environmental science – U1L8 Most rain forests are located near the equator. Rain forests have a tropical wet climate and are quite humid all the time. The yearly rainfall is often more than 100 inches a year. Tropical rainforests produce almost half of the oxygen on earth. Scientists say that more than half of all the world's plant and animal species live in tropical rain forests. Rainforests only cover less than 6% of Earth's land surface. The rain forest is home to the greatest biodiversity on

A biome is a group of ecosystems that share similar climates and organisms. In Miller and Levine Biology, 10 biomes are discussed. They are the Tropical Rain Forest, Tropical Dry Forest, Tropical Grassland, the Desert, Temperate Grassland, Temperate Woodland, Temperate Forest, Northwestern Coniferous Forest, Boreal Forest, and the Tundra. They all have a vast amount of differences between all of the biomes, and they will be discussed. Although not discussed in the book, the taiga is the biggest
