Viết đoạn văn về chủ đề: Should we keep animals in the zoo? Why / Why not

In my opinion,I think we should keep animals in the zoo. because:

• There are more chances of endangered species surviving due to no natural threat
• Scientists can study diseases that kill species and invent cures
• In a world, where nature and lands are being destroyed it gives the animals a safe haven
• People can see animals that they will probably never see again in their life time
• It is a great way to educate children that we are not the only inhabitants of the planet
