To adequately respond to your post would require very many pages.
Genesis 1:29 Then God said, “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food. 30 And to all the beasts of the earth and all the birds in the sky and all the creatures that move along the ground—everything that has the breath of life in it—I give every green plant for food.” And it was so.
As we have been informed by faith and the Church, scripture is literal. Its words are rich in meaning, generating great joy in their interpretation. The above quote from Genesis and especially yours from Isaiah, reveal how the world was initially created reflecting God’s gentleness.
The anger we face when we sin is the reality of sin itself, its destructiveness towards others and more so ourselves.
The words spoken in Genesis, it seems reasonable to believe, given their depth and the truth they reveal, were spoken by God to Adam and passed on by those who remained faithful as part of a growing dialogue between the Word of God and His people.
They do not contain every detail of creation. The fall of Lucifer is described later in scripture.
Rev 13:8 - All inhabitants of the earth will worship the beast - all whose names have not been written in the Lamb’s book of life, the Lamb who was slain from the creation of the world.
1 Peter 1:18 For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your ancestors, 19 but with the precious blood of Christ, a lamb without blemish or defect. 20 He was chosen before the creation of the world, but was revealed in these last times for your sake. 21 Through him you believe in God, who raised him from the dead and glorified him, and so your faith and hope are in God.
The veil of sin and the spiritual suffering that it brings is pushed aside, and we see at the very foundations of existence, here and now as well as in time, the gentleness of God and the extent of His love for us in Jesus Christ.
I can’t recall where I got the idea; I’m too busy and too lazy to look it up. Although it’s not stated outright in scripture, consider the possibility that before our fall and related to that of the angels, nature fell. Angels do God’s bidding from what I understand. Among those who followed Lucifer would be those who assisted in the formation of animals. And, that is how the serpent got into the Garden, which God permitted because it led to the greatest demonstration of God’s love for us.
As God gave us animal skins to protect us in this fallen world for which we were not made, nature’s balance was reestablished as life now gives itself to life.
Remember too that we eat the body and the blood of our Lord in the Eucharist.
There will be a greater peace and harmony at the end of creation’s journey through us in Jesus Christ, back to God.
That’s the short of it.
