Deforestation effects on the Amazon Rainforest and The Indigenous Indians
The Amazon Rainforest is the world’s largest tropical rainforest, most of it located in Brazil. About 10% of the world’s species are found in the Amazon. The Amazon is home to 40,000 species of plants and some of these plants are used for making new medication and vaccines, such as for cancer. Not only can we use the resources found in the Amazon for medical purposes, but it also produces about 20% of the oxygen we need. Despite the fact that the Amazon is a big part of our planet’s ecological system and is used in research, it is still being destroyed by deforestation. Deforestation is mainly caused by both agriculture and logging. Deforestation affects the environment

The Amazon contains over 300 different species of trees and “each tree hosts a unique variety of animals and insects, with some trees hosting up to 1,500 species of insects” (Boekhout van Solinge, 266). Trees are valuable to the ecosystem because it is used in several ways by the planet, such as being the host to plants, animals and insects. A few species of trees are profitable and so people practice selective logging, which is the practice of cutting a few selected trees while leaving the rest alone. All thought this may seem to be a preferred alternative to cutting down large areas it still has its consequences. In certain places trees are killed or severely damaged when one tree is harvested. This causes gaps in the canopy to increase and when there are “gaps in [the] canopy [it] allow[s] sun and wind to reach the forest floor, resulting in drier microclimates” (Fearnside, 682). Selective logging causes various changes in the forest’s composition and structure. When the interior of the forest changes this causes an impact on the plants and animals considering that certain species survive best in the shade and humidity of the inner …show more content…
Selective logging may not seem like the biggest cause of forest fragmentation, but “the detrimental impacts of selective logging may extend many years, especially when considering that many forest structural properties, such as deep canopies, associated with wildlife habitat in intact forests, are not likely to be regained for 30-50 years or more following logging” (Broadbent, 1752). Canopy openings caused by agriculture is much more vast and it can have bigger consequences because adjacent forests are damaged when the land is cleared. Forest fragmentation also causes changes in the water and aquatic systems in the forest, which can lead to changes in plant, animal and forest composition. It affects the surrounding area up to 6 miles into the interior forest. Forest fragmentation can lead to easier access for humans and a decrease in forest

    Deforestation is one of the major global issues of the contemporary world. Humans and animals depend on trees for the production of oxygen so that they can breathe, yet universally, world annual deforestation is estimated at 13.7 million hectares a year. The annihilation of such immense quantities of forestland will have devastating consequences in the future, especially considering that fewer trees will result in a smaller intake of carbon dioxide, adding more emissions to the greenhouse effect. Forests cover 31% of our planet’s land, they fulfill many roles such as providing renewable raw materials and energy, maintaining biodiversity, and protecting land and water resources; forests are heavily exploited, but important efforts are being…

    The efforts by the conservation organisations have improved the prospects of forests and have significantly reduced deforestation. But more need to be done, and we all play a part in it. It can be something as little as saving or recycling paper. If not, it is us who will bear the consequences. Many species of plants and animals will continue to go extinct, temperatures will continue to rise, ecological disasters will keep on happening.…

    However the destruction of the rainforest is by far our greatest loss. Many of the tropical rainforest are located on or around the equator and cover about seven percent of the earth’s surface. The rainforest contain more than half of the world’s population of plants and animals. The rainforest contains many different types of plants where medicine is derived from. According to an article posted on the Rainforest Adventures website “A typical four square mile patch of rainforest contains as many as 1500 species of flowering plants” (About the Rainforest).…

    People get their everyday items from trees. According to the article, Deforestation by World Wildlife Fund, “Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter.” This explains that deforestation is unnecessary since it’s more a lot more people can benefit from the forest than deforestation. It’s where some of the things we need are there. Also, later in the article it states “Deforestation comes in many forms, including fires, clear-cutting for agriculture, ranching and development, unsustainable logging for timber, and degradation due to climate change. This impacts people’s livelihoods and threatens a wide range of plant and animal species.…

    Therefore, the plants and soil are both lost. On the other hand, the trees that were originally in the rainforest are strong enough and can hold the soil. The soil then provides nutrient dirt for other plants and organisms. The eroded soil can also change the landscape of the area around it. Also soil saturates waterways and disrupting the food chain.…

    For some organisms that fail to reproduce faster in order to compensate the loss, will end up in extinction. • Apart from large scale deforestation, localized deforestation can lead to extinction too. • This is because of some unique and exotic species that only exist in minute, isolated areas at certain locations in the world. • In other words, these unique species cannot be found elsewhere in the world. Disruption of water cycles • Trees play a major role in regulating the water cycle locally by aiding in maintaining equilibrium between the water on land and water that is in the atmosphere (water…

    “Forests cover 31% of the land area on our planet.”(Deforestation | Threats | WWF). With the the prevalence of deforestation, it messes up animal living because the trees are the animals homes and without the trees the animals do not have homes. The WFF (World Wildlife Fund) has been working for over fifty years to help stop or slow down deforestation. The earth is under a threat for losing much of our forest. Humans are also affected by the loss of trees as trees are used to purify the air.…

    In watershed where forest are degraded or destroyed, minimum flows decrease during the dry season, leading to drought, while peak floods and soil erosion increases during the wet season. Thirdly logging those trees can affect the biodiversity of the animals living in that area. Some animals are very sensitive they often migrate once their environment is changed. This proves that logging is not just affecting the lives of human but also the…
