Yes, but the endangered species we are commissioned to save are HUMANS who are spiritually endangered.
Matthew 28:19-20
(New International Version)
19 - Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 - and teaching them to obey everything I have command you. And surely I am with you always, to the very end of the age.
I love animals. They are intriguing, instinctively intelligent and fun to watch. God and Jesus loves them too. Proverbs 12:10 says "The righteous one takes care of his domestic animals, But even the mercy of the wicked is cruel." (New World Translation)
I love people more. Jesus loved people also. Preaching and teaching the truth about God and his purposes is what he did and commanded us to do, which animals cannot appreciate.
The Roman government was oppressive toward Jews and when Jesus was on earth he did not get involved. Why? He knew his heavenly Father set a date that is known only to Himself, to end all governments. (Daniel 2:44; Mark 13:32) Jesus' main goal was to preach about this kingdom and what it would do for mankind and subsequently all living creatures.
Getting overly involved in matters outside this can distract us from what Jesus said is most important.
Reaching the hearts of people with the Bible, its laws and principles, will help to change how they treat animals. Otherwise it is like striving after unattainable the wind. Hebrews 4:12; Ecclesiastes 4:4
There are so many groups for so many causes, many good, some against Bible principles and laws. They cannot bring any lasting hope for mankind, only God can and he will use his son Jesus Christ to accomplish it.
Daniel 2:44
(King James 21st Century)
And in the days of these kings shall the God of heaven set up a Kingdom which shall never be destroyed; and the Kingdom shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever.
Mark 13:32
(Contemporary English Version)
No one knows the day of the time. The angels in heaven don't know, and the Son himself doesn't know. Only the Father knows.
Hebrews 4:12
(English Standard Version)
For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.
Ecclesiastes 2:17
(English Standard Version Anglicised)
So I hated life, because what is done under the sun was grievous to me, for all is vanity and a striving after wind.
