In recent years, there has been a vast increase in discussions between people about animal rights.

 has had a harmful effect on them.

. 
     In conclusion, I believe that humans will realise that the mockery of Use synonyms

 is unethical, and aggressive and reveals improper behaviour. We should encourage them to preserve Use synonyms
animals
, particularly those that are endangered.Use synonyms
