Surely manufactures and food production benefited from animals can enrich human’s lives and promote the growth of social economies. To take an example, animal furs can be made into clothes and their meat into food cans. However, once such slaughter of animals causes serious problems to mankind, like ecological deterioration, this kind of economical prosperity would be completely pointless for human generation. After all, monetary methods cannot create those species of creatures to revive if they are extinct.

Unfortunately, that paragraph is not coherent. By the time you get to the end the subject has changed from what it is at the beginning. You need to have more focus.
