While central america encompasses a small area of land, describe the topography, environment, climate, and dominant features of this land mass, as well as any human impact?

Central America is very grassy and dense. the weather is usually damp, moist, and foggy. there are lots of rivers, marshes, waterfalls, swamps, lakes and bays. the largest human impact would be the panama canal which is used as a major trade rout through central America and it is also a big tourist attraction.
