During natural events, some parts of the forest ecosystem continue to function, which leads to slow recovery of lost habitats.

Why are so many animals in the Amazon rainforest endangered?

Main Reasons Species Are Endangered 1 Destruction of the ecosystem 2 Low level of genetic variability 3 Poor dispersal ability 4 Pollution 5 Large area requirements 6 Hunting and fishing 7 Concentrated population 8 Introduction of exotic species 9 Concentrated population 10 Long distance migration

How are cattle ranches harmful to the Amazon rainforest?

In particular, cattle ranches and the beef industry are by far the most destructive to the Amazon, and the environment at large. Forest clearing, burning, and cutting, destroys natural habitats of wild animals – including a number of endangered species – to make pastures and fields for grazing cows.
