If insects do disappear, what will be the impact on plants, animals, and humans?

If insects do disappear, it will have a wide range of effects on plants, animals and humans.

1.Effects on flora and fauna:

Insects are the most fundamental link in the biological chain and are food for many plants and animals, such as birds and small mammals. At the same time, they are also predators of other insects and invertebrates. If insect populations decline or disappear significantly, it will lead to a chain reaction throughout the ecosystem, causing large fluctuations in populations and even extinction.

2.Effects on humans:

The effects of insects on humans are also very important. First, they play a key role in agricultural production, such as pollen dispersal, pollination, hybridization, etc. Without enough insects to act as pollinators, yields of these crops will drop dramatically, affecting agricultural production and global food**.

Secondly, many insects are disease vectors for humans, such as mosquitoes can transmit diseases such as malaria. If all the mosquitoes were gone, people would no longer need to take measures to prevent the spread of these diseases.

3.Impact on the environment:

The impact of insects on the environment is also very important. They play a key role in soil biocycling and nutrient transport, helping to keep the soil healthy. In addition, many insects are indicator species of ecosystems, and their disappearance may indicate broader ecological problems.

As a result, the disappearance of insects will have a profound impact on plants, animals and humans. However, it is important to note that the number and variety of insects are very large, and the impact of different species of insects on the ecosystem is also different, so analysis needs to be done on a case-by-case basis.

Without insects to feed on nectar, the plants will become extinct, and then the entire earth will enter the era of mass extinction, and of course people will not survive much (only the rich and powerful remain).

If the bees disappear, the flowers will not be able to scatter pollen.

Humans built civilizations, but insects are the masters of this world, after all, more than half of the known species of eukaryotes are insects. So if all the insects suddenly disappear, you will notice that in the summer there will be no more cicadas chirping and fireflies flickering, and there will be no bees pollinating apples, cherries, peaches ......

This will lead to an imbalance in the ecosystem, and the survival of human beings will also be threatened, because many insects can be used as food for humans, which contains high nutritional value and can also eliminate some harmful substances.

Then many species in nature will become extinct, because insects are a very important link in the biological chain.

Extinction of living things. Because insects in nature play an important role in the biological chain, if there are no insects, then the biological chain will be broken, and eventually lead to the extinction of the organism.

Summary. The diversity of insects plays an important role in plant pollination, decomposition of animal carcasses, and soil treatment, and they are an essential link in the ecological food chain, which can be herbivores, carnivores, and parasites. In particular, the decline in numbers and extinction of essential insect species, which are closely related to the survival of many animals, will directly affect natural ecosystems and human life.

The extinction of insects will have a direct reaction on human society.

Similarly, insect species, as a major component of the earth's ecological environment, are closely related to human survival, and their extinction will directly react to human beings. A 1997 assessment reported that one-third of the world's crops are pollinated by wild insects, and that without these wild insects in the ecosystem, global agriculture would lose $117 billion!

What would happen to the world if animals and insects disappeared.

Hope mine is helpful to you.

You mean the disappearance of the number of species on Earth?

Many species disappear every day, but at the same time, many new species are born.

The earth is a closed loop with strong environmental self-healing ability, and everything inside it is cyclically adapted, and when the environment changes, the environmental variables are changed.

The matching flora and fauna will also change. When a species disappears, it will affect the species it matches, and the related species will either disappear together in chains, or find a surrogate to evolve and fill, and when the evolutionary filling, a new species will be generated.

For example, when chickens disappear, humans replace them with other trembling heads, or breed new ones.
