If you don't know what Marmoset monkeys are here is a little more about them.
They are Native only to east-central Brazil. Most marmosets are very small monkeys with relatively long tails. They stand only 14 cm tall and the key to their survival is that they work together in a pack to collect food and stay safe.
In my opinion I think that they should leave the monkeys in their natural habitats because other wise they will be at more risk of becoming endangered and what will happen to them at the end of the year of the monkey. They might be killed if people don't want them any more.
Thats My opinion what's your tell me in the comments below
