Rainforest Rainforest contains approximately two-third of the world’s plant and animal species. It has one of the world’s most spectacular ecosystem. The name ‘rain’ forest, indicates that it receives high rain fall throughout the year. Not limited to that, the trees also release water to the atmosphere by transpiration, forming dense clouds that surround the forest. Hence, even on non-raining days, the forest remains warm and humid.
They say that there are even some undiscovered species hiding in there, maybe one could help us cure cancer. According to Treehugger, “The Amazon Rainforest, one of the largest and most diverse ecosystem on the planet, has been a virtual treasure-trove for ambitious biologists aiming to uncover new species,” (Stephen Messenger, Amazon Rainforest teeming with Life). The Amazon consists of different layers because of the amount of sunlight and water each plant needs. Large trees create a layer of leaves blocking most of the sunlight from filtering in. There is a variety of underbrush and plants that require water but not a lot of sun.
The three groups are ecological services, social benefits and biological resources. Tropical forests most importantly provide us with some critical life sustaining ecological services. Services like oxygen production, water purification, climate moderation, conversion of solar energy from the sun into carbohydrates and proteins, soil formation and greenhouse gas removal (Biodiversity BC, 2007). Though these services can be provided by green plants in general, through its large presence all around the world, tropical forests play a key part in contributing and maintaining these ecological
As it is extremely hot and humid, animals and plants got to adopt to such kind of climate. The four layers of the rainforest are – Emergent layer, Canopy layer, Understory layer and Forest floor. Emergent layer is the tallest trees towering above all the vegetation below which could be 200 feet and above from the floor. Trees found in such area are of broad leaves and the woods are usually hard. Animals found in such towering trees are such as bats, butterflies, eagles and monkeys.
The rainforest helps maintain and regulate the continuous recycling of water that filter to the rivers, and lakes without this it would be more droughts, it supports air quality and helps trees absorb carbon dioxide and produce H2O. It also provides wood, fiber and fuel and it is also important to indigenous communities supplying fresh water, wild foods,wild fisheries and wood for fire and building. People who live near the rainforest also hold a somewhat cultrue or spiritual bond giving them a sense of
Tropical forests are considered the richest forest on earth because of high number of biological communities that home of a large number of biodiversity (Baraloto et al, 2003). These forests provide ecosystem services such as species conservation, soil erosion prevention and habitat preservation of plants and animals (Armenteras et al 2009). Over-exploitation of these forest has resulted the rapid loss of forests cover which recognized as one of the environmental and economic problems around world (Mani and Parthasarathy 2006). Tropical forests are declining at alarming rates globally, reducing annually by 1-4% of their current area (Laurance 1999). The relative increased of anthropogenic pressures had led to agricultural expansion and over grazing of livestock (Anitha et al 2010).
Due to their unique characteristics, they have been considered as natural assets that can deliver ecosystem services from local to regional scales (Moor et.al, 2015). Ecosystem services are the benefits that society obtains directly or indirectly from ecosystems. They are the processes that are utilised and valued by people. Bergkamp and Orlando (1999) grouped wetland functions into four types which are regulation, provision of habitats, provision of information and production. According to Clarkson et.al (2013), wetlands have three important regulating services which are water quality improvement, flood control, and carbon management.
The nature of aquatic systems is in a very delicate balance that is easily altered when chemicals and nutrients are added to the water. One example of this are the Cladophora, which are attached green algae in Lake Ontario. It grows during the summer and lives on nutrients such as phosphorous that make their way into both naturally and through pollution in the form of soaps and fertilizers . The more pollution that flows into Lake Ontario the faster the decline in aquatic health. These contaminants that flow into the water system effect the food web to a large extent.
have so many roles in human to collect water for example the uses of residential, industrial, agricultural, educational, experimental environment and forest land use. Watershed area contain million species of plant for medicinal or other industrial that not all have recognize until today and as a wildlife habitat. With the million species of plant and wildlife, watershed also promote tourism industry increase in Malaysia. Whereas, each year the total of tourist increase directly affect of the foreign exchange. So it’s also involve in importance of economic industry in our country.
For instance, deforestation of tropical rainforests has seen a direct loss of species and indirectly through increasing threat of global warming. The tropical rainforests hold at least 50% of the world’s species. Besides habitat fragmentation, a division of ecosystems and populations of species into smaller isolated, lead to biodiversity through increasing vulnerability of some populations to disease and other stressors. Pollutants such as acid air rain pollution, fertilizers, pesticides, and herbicides destroy and alter habitats and their species as
