Thecauses of deforestation which is development of agriculture and economicpressure has lead to several effects which is not only affects the people, butplants, animals and environment. These effects has negative impacts especiallyon land and biodiversity. Deforestationhas many effects toward every species on the earth and environment, and one ofthe impact is on land. The biggest problem will be faced by earth afterdeforestation is soil erosion (Lindsey, 2007). The soil was attached by thetree roots, so without it the soil was easily eroded as the nutrients content islost. The erosion are getting higher and the lost of nutrient provided byliving plants will happened after the slash and burn method. Soil erosion wascaused by planting commercial crops like palm oil because the soil cannot holdonto the roots.
Besides soil erosion, landslides and flooding occurred withsame reasons. The soil become compacted when the area has turned into cattlegrazing, and it will be hard to recover the forests. For example, soil erosionhas reduced the crop harvests during the Maya civilization because the soil hadbeen washed away from the hills. The wars for food between the Mayas beganbecause of the loss of food production, and death rates were very high(Pakenham, 2005). Infertile soil will cause eco-system become worst that can affectsanimals and plants who live in the forests and their habitats. Anothereffect of deforestation is it harms the biodiversity (Lindsey, 2007).
Tropicalrainforests are home to much of the world’s biodiversity. Based on NationalGeographic (2009), around seventy and eighty percent of world’s plants andanimals live in the forests. Deforestation which is massive destruction offorests has caused the loss of their habitats, and it is hard for them tosurvive (Bradford, 2015). Because of their habitats have been destroyed, itwill lead to the extinction of the species (Pakenham, 2005). The extinctionrate were expected to rise between 7000 and 27000 species a year (WRI, 1993).To illustrate, tigers have lost 93% of their historical range because their habitathas been destroyed to clear the trees for agriculture (WWF, 2018). The negativeimpact of extinction is considerably loss of beneficial medical plants asdeforestation kill off plants that promise cures for countless disease (Goldenand Miller 1994). For example, a small plant native to Madagascar calledCatharanthus roseus has medical properties as it was very effective in thetreatment of cancer (Wilson, 1989).
One of the five other species ofCatharanthus was very close to extinction because its habitat was threatened bydeforestation. The last couple of decades, our world has lost so many speciesof plants and animals because of deforestation (Conserve Energy Future, 2013).Toconclude, deforestation is an important issue that need to be prevented. It wasa huge concern nowadays since the number of trees were cut down rises. Ithappened due to the growth in population, and the need of people to provideagricultural land and faces the economic pressure. Deforestation has causedfewer trees to grow, so it leads to soil erosion as there are no nutrientsprovided and the loss of habitats that caused species to become extinct.
PresidentRamiro de Leon Carpio of neighbouring Guatemala has said, “If we fail topreserve the rain forests, more people will die than have perished in worldwars..”. Deforestation is a part of people’s action, so people are responsibleto prevent what have they done, and find solutions to save the world.
