Unfortunately, the people that live the regions where the tropical forests are, are not well educated as to how to manage the land, and a big problem is that the soil of the rainforests is only good for 2-3 seasons, because it spends and erodes very quickly.

Blubber is a fat-storage organ in mainly water-living mammals. It stores a large amount of brown fat tissue (brown adipose tissue) in young animals as compare to the adults that provides extra thickness to it. The extra amount of brown adipose tissue provides heat that acts as an effecient thermal insulator and helps on thermal regulation.
Thus, the blubber in baby dolphin shows a different composition of fat storage tissues that helps to survive them in cold temperature of ocean in their early stages of development.
