Solutions to Prevent their Extinction :)

this is the process how they do injection for vitamins to zebrafish

Some scientist around the world already start to make some action by creating chemicals that includes nutrition and vitamins and they would put those chemicals inside the animals food when they feed them so that when they eat it the chemicals would start to give them nutritions and vitamins to their body so that they can live a longer and healthier life. Scientist also recommend the zoo keepers to feed animals more with vegetables rather than meat because vegetables can clean their stomach. The chemicals are still in progress but some scientist already start to test it to the Zebrafish and the chemical is near to perfect so... maybe by next year the chemical would be used to the ones that are very critical in number.

Limitations of the solution: The solution still needs to be tested in some animals so when they test and it is a failure they have to keep on making and keeping on testing making the animals die faster which bad because the animals can die because of the testing. So the scientist should test the chemicals lesser so that less animals will die and that those animals won't get extinct.
Benefits of the solution: Chemicals are very useful because it is something like a drink but with more minerals and vitamins so when the chemical is already successful more animals will be more healthy and they will have a longer life.
