Chile has about 4.5 million hectares of wetlands. (I don’t know if you’re thinking the same thing as me: that’s a lot!)

To better understand this topic, these is the definition that I’ve found for wetland:

“Any normal flat area where the surface of the soil is covered with water permanently or seasonally, is a wetland”. These are natural refuges for wildlife and wild flora, sources of fresh water, recharge for aquifers and true filters for sediments and pollutants.”
