Allow me to correct your first sentence. Animals are not subject to sabbaths. Their essentials must be cared for, like water and food. People who are responsible for pets, cattle, flocks don't sin by providing required care on a Sabbath, but must be responsible not to abuse. If a cow sliped into a mud hole it was entirely OK to rescue it any day of the week.
I think issue of animal care, being seen to quite well, pales compared to the current world issue of climate change and global warming. Mankind will not be able to do enough to change that. Since it's been cyclical over tne millennia, by the time CO2 is reduced we might resume volcanic eruptions that tend to cool earth, needing the CO2 back to level it out. The USGS has been predicting some major events, like Yellowstone Park exploding to put the eastern US in great jeopardy.
God laid claim to planetary control, and is the only power to change anything significantly. Here's some interesting claims by the Lord:
Jeremiah 4:23-26 I looked on the earth, and lo, it was waste and void; and to the heavens, and they had no light. I looked on the mountains, and lo, they were quaking, and all the hills moved to and fro. I looked, and lo, there was no one at all, and all the birds of the air had fled. I looked, and lo, the fruitful land was a desert, and all its cities were laid in ruins before the LORD, before his fierce anger.
Hosea 4:3 Therefore the land mourns, and all who live in it languish; together with the wild animals and the birds of the air, even the fish of the sea are perishing.
Those seeming environmental disasters concern rebellion of Israel and their punishment by God. Man didn't cause that. God brought it on them, suddenly dismantling their land of plenty.
Because of world rebellion against God, we shall not have a comfortable world. No matter what we try, we won't change what builds up into the multiple disasters of the tribulation Be sure everyone you know is ready. Next, a powerful unfulfilled prophecy of that coming seven year long catastrophe.
Isaiah 24:1-6 (KJV)
1 Behold, the LORD maketh the earth empty, and maketh it waste, and turneth it upside down, and scattereth abroad the inhabitants thereof.
2 And it shall be, as with the people, so with the priest; as with the servant, so with his master; as with the maid, so with her mistress; as with the buyer, so with the seller; as with the lender, so with the borrower; as with the taker of usury, so with the giver of usury to him.
3 The land shall be utterly emptied, and utterly spoiled: for the LORD hath spoken this word.
4 The earth mourneth and fadeth away, the world languisheth and fadeth away, the haughty people of the earth do languish.
5 The earth also is defiled under the inhabitants thereof; because they have transgressed the laws, changed the ordinance, broken the everlasting covenant.
6 Therefore hath the curse devoured the earth, and they that dwell therein are desolate: therefore the inhabitants of the earth are burned, and few men left.
