Keywords
💡Deforestation
Deforestation refers to the large-scale removal of trees and forests, often for the purpose of converting the land for human use, such as agriculture or urban development. In the video's context, deforestation is a critical issue because it leads to the loss of biodiversity, contributes to climate change by releasing carbon dioxide, and disrupts the water cycle. The script mentions that humans have cut down nearly half of the world's estimated 5.8 trillion trees since the advent of agriculture, with a current rate of 15 billion trees being cut down each year.
💡Biodiversity
Biodiversity is the variety of life in all its forms, including the variety within species, between species, and of ecosystems. The video script highlights the impact of deforestation on biodiversity, stating that if all trees were cut down, almost all animal species that live in the forest would start to go extinct, as they would lose their habitat and food sources.
💡Carbon Dioxide (CO2)
Carbon dioxide is a greenhouse gas that is released into the atmosphere through various natural and human activities, including the burning of fossil fuels and deforestation. The script points out that the rotting of nearly 99% of the trees on the forest floor would release 35 billion tons of CO2, contributing to air pollution and making it unsuitable for human respiration.
