Deforestation can have a huge impact on ecosystems. This practice can alter all aspects of the biotic and abiotic parts of an environment, including the Amazon rainforest. The biotic parts of the Amazon that are altered by deforestation include: BiodiversityThe Amazon is known for its biodiversity. The forest is home to many species that have adapted to unique lifestyles.
Each species requires a certain habitat, and certain types of foods in order to survive. But when one of these essentials are taken away by deforestation it can have a dramatic effect. Like when the Amazon cleared to make space for crops such as corn or soy, both these plants will take resources that are meant for other plants, which can cause a decrease in other native species populations. However, if crops are introduced slower (less at a time) and do not take to much of other resources they can actually increase the rain forest’s diversity since they can act as a habitat for other species as well.
The same goes for animals, when new species are introduced they can disturb the ecosystem.DiseaseA possible, and indirect consequence of deforestation in the Amazon is the spread of diseases. More specifically, diseases that come from birds like the avian flu. Climate change has already affected the migration patterns of birds so they end up moving to areas that have been cleared because of the better habitat. The birds will eventually end up spreading their diseases to other populations of birds in the rainforest as well. This is a problem because diseases that are shared through insects, such as malaria and Lyme disease are more common in open spaces that are exposed to more light putting birds and other species at risk. These diseases can also infect humans that are near these areas. Abiotic affects that are altered by deforestation include: Water ChemistryDeforestation in the Amazon can also have an affect on nearby streams, rivers and other water sources.
This occurs when nutrients in the soil are removed by runoff or to much water. This happens when any water, for example rain water, takes away the nutrients in the soil and carries them to a different place. When the water carries the nutrients to deforested areas they are proven to have lower dissolved nitrogen levels, higher nitrate levels and an above average temperature of 20 – 23 degrees Celsius) compared to regular forested areas.
Temperatures increase in the soil because there are no longer any trees t block the harsh rays of the sun from the soil. These factor can disturb species that live in bodies of water because they are not use to the new levels of nutrients in the soil which can negatively impact the ecosystem.The AtmosphereDeforestation may be an issue that directly affects the forest and other surroundings of the rain forest, but the atmosphere is affected by it too. 17% of all greenhouse emissions are a result of deforestation. The emissions are from both burning and cutting the trees down but it is also from the loss of trees, which means there aren’t as may trees that are preforming photosynthesis, which removes carbon dioxide from the atmosphere (a greenhouse gas).
The carbon dioxide inside the trees is also released when they are chopped down as well. As a result, there is more arbon Dioide in the air which will contribute to global warming.Soil ImpactThe Amazon Rain forest’s soil is also affected by deforestation. The soil provides nutrients for all of the plant life in the forest, which can either be a negative or positive thung dependingon the situation.
Soil in deforested areas have a higher temperature, which causes the carbon in the soil to form carbon dioxide because of being exposed in the Sun. The carbon dioxide in the soil are primarily from decomposed vegetation, soil erosion (when an area of land loses its top soil from rainfall) and surface runoff (water causing things to move) that are most common after rain. Soil erosion is more common in drier areas where little to no vegetation is present to prevent the movement of soil and to absorb nutrients.
