Soil Erosion: This is the wearing away of topsoil due to factors like water, wind or tillage. It's similar to how constant use can wear down the keys on your computer keyboard.
Deforestation: This refers to the removal or clearing of forests for non-forest uses such as farming or urban development. Imagine it like removing all the books from a library to make space for a gym - you're changing the entire purpose and function of that space.
Drought: A prolonged period with less-than-average amounts of rain, leading to water shortage. It's like when you forget to refill your water bottle before a long hike - there just isn't enough hydration available.
