Which conditions are driving Climate Change (Global Warming)?
A. desertification & overharvesting
B. deforestation & desertification
C. deforestation & invasive/non-native species
D. burning fossil fuels & greenhouse gas emissions
The correct answer is B. Deforestation and desertification are two key conditions driving climate change (global warming).
Deforestation refers to the large-scale removal or destruction of forests, primarily for agricultural expansion, logging, or urban development. Trees play a crucial role in mitigating climate change by absorbing carbon dioxide (a greenhouse gas) from the atmosphere and releasing oxygen. The loss of forests leads to increased levels of carbon dioxide in the atmosphere, contributing to global warming.
Desertification, on the other hand, refers to the process by which fertile land gradually transforms into desert-like conditions. It is primarily caused by factors such as overgrazing, inappropriate agricultural practices, and climate change. Desertification can contribute to global warming as arid and degraded land retains less moisture, leading to reduced vegetation and carbon sequestration.
While both A. desertification and overharvesting and C. deforestation and invasive/non-native species are environmental issues, they are not directly associated with driving climate change.
