Throughout the weeks, we have explored the impact of human activities on all four spheres of the Earth as apart of our Science course.
The experience was both demanding and stimulating, and it certainly piqued my interest.I learned the way human-induced activities affect one sphere which then leads to defects to the other three.
Deforestation negatively impacts the environment by increasing carbon emissions and disrupting natural ecosystems. It plays a significant role in global warming and climate change, as trees release stored carbon into the atmosphere as carbon dioxide when they are cut down. As vast areas of forest are removed, the exposed land suffers degradation, and countless species lose their habitats. Additionally, Indigenous communities that rely on these forests for their livelihoods face significant threats to their way of life. The dangers to nature differ across various regions. For instance, in tropical areas, agribusiness often clears forests to create space for activities like cattle ranching, palm oil production, and soy farming for animal feed. The global demand for wood products, whether for disposable paper items or hardwood flooring, also poses a threat to forests everywhere.
While trees and wildlife may eventually return, the effects of deforestation extend beyond what is immediately visible.
Forestry activities and subsequent cultivation methods lead to decreased water infiltration and heightened runoff. The absence of trees means there is no mechanism to retain water, which exacerbates soil erosion and raises the likelihood of flooding, thereby increasing the risk of pollutants contaminating adjacent water bodies. These practices pose significant threats to Tangaroa.
Currently, approximately fifty percent of New Zealand’s land has been transformed into agricultural areas; for instance, much of the river flats along the west coast have been converted into pastures. The clearing of forests has played a significant role in the extinction of native species. Indigenous communities and rural inhabitants frequently rely on forests for their sustenance, which encompasses food, housing, and traditional medicinal practices. The process of deforestation disrupts these vital ecosystems, stripping communities of crucial resources and threatening their cultural identity. Maori, in particular, have a deep dependence on their whenua for their well-being.
When forests are cleared or disturbed, they emit carbon dioxide and other detrimental gases. The loss and degradation of forests contribute to 10% of global warming. Combating climate change is impossible without halting deforestation. It is imperative that we prioritize the protection of forests, especially the forest of Tane-Mahuta, now more than ever.
Deforestation has quickly become a topic that I am passionate about due to the number of effects it has on the world that we live in. It may pay well but soon we will have to pay it back to Papatuanuku.
