A look at the botanical treasures, both known and undiscovered, that exist within tropical rainforests the widespread destruction of tropical rainforest ecosystems and the consequent extinction of numerous plant and animal species is happening before we know even the most basic facts about what we are losing. The amazon basin contains the world's largest rainforest, which represents over 60 percent of the world's remaining rainforests more than half this forest lies in brazil the amazon rainforest affords the planet with irreplaceable ecosystem services that are increasingly being recognized by researchers and policymakers. There are many different plant and animal species in a rainforest, but the trees define the way a rainforest looks plants and animals are important because they are a part of the system that makes the rainforest work rainforests are a very important part of the earth's environment, so the plants. Benefits of biodiversity it is important to note that the majority of ecological resources that biodiversity provides (see benefits to earth) are nearly impossible to replace for instance, the pollination performed daily by bees and insects would be impractical for humans to attempt.
In tropical forests all organisms are dependent to some extent on bacteria and fungi some animals such as wood and leaf-eating insects depend on symbiotic gut microbes to digest cellulose in their food supply, while other insects utilize fungi directly as a food source. The economic contributions of forests beyond what is available in official reports country‐ and region‐specific efforts indicate that where such data are reliably available, 41 role of. Importance of forests forests and biodiversity are key to all life forms the richer the diversity of life, the greater the opportunity for medical discoveries, economic development and adaptive responses to such new challenges as climate change.
Rain forests play an invaluable role in sustaining life, but every year, large portions of them are cut down for logging, mining, and cattle ranches. Human-induced deforestation plays a significant role in causing rainforests to release carbon dioxide, as do other factors, whether human-induced or natural, which result in tree death, such as burning and drought. Forests play an important role in the purification of the atmospheric air during the day, trees and plants absorb carbon dioxide for photosynthesis and give out oxygen as such, they help in the purification of the air that we breathe. By most accounts, deforestation in tropical rainforests adds more carbon dioxide to the atmosphere than the sum total of cars and trucks on the world's roads.
By tierney smith forests cover 30% of the world's land surface, and are home to around 90% of the world's land-based animals, plants, insects and birds they are also one of the world's largest carbon sinks, absorbing 24 billion tonnes of carbon dioxide each year and storing billions more. Tropical rainforests are absorbers of carbon dioxide scientists now say that the rainforest ecosystem in the brazilian amazon is a net absorber of carbone dioxide, and therefore helps to protect the earth against the greenhouse effect. Rain forest destruction (in both tropical and temperate climates) is caused almost entirely by purposeful cutting of the forest commonly, this is for timber harvesting but in many tropical areas, rainforest is simply burned so that the people can have new farm lands. Forests play a critical role in sustainable development, from combating soil erosion in agricultural fields to mitigating the effects of climate change we all know that the lack of clean water and clean air can result in adverse social and economic impacts on communities and economies.
Edit item text: conservation international strives to protect tropical forests around the world, working directly with the communities who live in, and depend on, these forests through science, policy and partnerships, we work to show that forests are worth more standing than cut down. The importance of forests and trees in agricultural systems and the nutritional importance of forest and tree foods highlight their role in both the sustainability and nutrition-sensitivity of food systems. Biodiversity or biological diversity is a term that describes the variety of living beings on earth in short, it is described as degree of variation of life biological diversity encompasses microorganism, plants, animals and ecosystems such as coral reefs, forests, rainforests, deserts etc.
31 the tree's significance as a link to culture and belief 32 the forest as a location for social, cultural and religious activities 33 the symbolic and sacred significance of particular forest resources. Large forests also play a role in weather and rainfall patterns and micro-climates for example, the amazon rainforest creates conditions that result in regular precipitation for lands to the south that are productive agricultural areas and are thought to even enhance rainfall in the great plains of the united states. For regulating climate, rainforest play an important role, the destruction of tropical rainforest which is the most serious eco development problems encountered in recent decades these tropical rainforest is not only for a variety of animals, plants, and insects, an important for living perches off environment and tropical rainforests are also.
