What would it be like if there was only one animal left on Earth?

Then the earth died. The earth is dead, how can humanity survive. Animals not only eat plants, but more importantly, they will help plants reproduce, without bees, many plants will not be able to sow seeds, without animals loosening the soil and decomposing plants in dead areas, the earth will soon freeze, and plants will not be able to survive.

Moreover, plants will produce a large amount of oxygen, increasing the oxygen content of the atmosphere, and a single lightning bolt can easily set a forest on fire. In short, animals and plants complement each other, and without one, the other will quickly perish.

Because the structure of the human digestive tract and digestive system is actually biased towards the carnivorous omnivorous intestine, and there is a lack of effective digestion of cellulose and fructose metabolism, our energy utilization rate of plant foods is actually very low. In the absence of animal food supplements, the current production of plant foods will not be able to meet the ...... of all living human beings on the planet

I remember the opposite: don't let humans be the last animals on earth. If such a situation really occurs, it can only mean that the environment on the earth has deteriorated to the greatest extent, the earth can no longer survive, and human beings must interstellar migration ......I'm going to think about it, and I'm terrified.

Every living thing on the earth has its meaning of existence, they are all creatures on this earth like human beings, if only human beings exist alone on this earth, then human beings will also become extinct.

A: If there were only humans in the world, there would be no other animals and there would be loneliness. If you don't succeed in the duel, you may also have to eat people. Because a world is made up, there should be everything. The earth can survive only by filling plants with various ecological animals and filling plants.

If there are no plants on the earth, no photosynthesis, no oxygen, human beings will be extinct immediately, but we should also think about it, if there is a day, the earth is not suitable for human habitation, it is estimated that human beings will find a suitable place to live, do not need to think about it.

There is mainly no meat to eat, and 70% of the world's population has little contact with animals, especially in cities. As long as there are men and women, if the plant can still grow normally, it will not, provided that there are both men and women.

It's impossible, but it's respectful of the questioner. As long as there are plants, food, water, and sunshine women, I believe I will not be alone. In fact, each of us is enjoying solitude, so why care if there are animals or not? First of all, I don't value meat and it's dispensable.

This is impossible, because the rich and colorful biological chain of the earth finally created human beings, human beings are the top of the biological pyramid, if the foundation collapses, the spire cannot survive at all, let alone loneliness?!

Humans and animals live in each other, and when animals die, humans perish.

I think it's going to be very lonely, the biological chain is completely messed up, and I don't think humans will survive for long.

I can only be the first: human beings are still one of the animal species according to the classification, but compared with other animals, human beings are constantly undergoing great changes, which should be because the earth has chosen human beings and given us human beings continuous opportunities to make us humans from the original apes.

Humans who continue to evolve to the present with high intelligence and high thinking, after all, there is a law on the earth, and a new overlord will appear every once in a while, and the current overlord is our human beings, although the gap between humans and animals is very large, but it can also be seen that we are far superior to other animals in many aspects, and the ability of many kinds of animals has been concentrated at many points.

Only the brain has a high IQ, and the animal brain purification is limited from but but each animal has its own ecological niche.
