habitat loss and climate change

overharvesting and exotic species introduction

Explanation:

The pet trade is one of the main threats to biodiversity on the planet and can cause the extinction of several species in the medium and long term. Trade in extinction animals often involves wild species being removed from their natural habitat to another habitat entirely different from yours.

This trade, in addition to causing the species to shrink in their natural habitat, can lead to the introduction of exotic species that can become a pest and end up with the extinction of another species.
