Plants play a huge role in the existence of our planet, as well as the direct existence of life on Earth. However, why is life on Earth impossible without plants? After all, it would seem that the absence of trees in dense urban areas and modern megacities only affects the fact that the areas become not entirely cozy, and also do not have places for recreation. We will look into this issue today.
Since school, most of us remember that plants serve people and everything to the globe by producing oxygen. However, most people are quite skeptical about this fact, without thinking that such “help” from plants can be significant. However, if you look at the actual data, you can find out that just one single tree is capable of releasing such an amount of oxygen during the day that will be enough for three people to live during the same day. Now imagine how much oxygen a whole forest or even a small forest belt produces in a day/month/year.
Another important function for which plants are responsible on our planet is the absorption of carbon dioxide. Of all the objects present on Earth, it is plants that are capable of performing such “work” and cleaning our atmosphere from unusable CO2 gases, because if its level in the atmosphere exceeded acceptable standards, this would all lead to an unfavorable outcome for all living things.
We should not forget that plants are directly involved in the process of soil formation. And this is one of the most important processes, occurring on our planet, because without it we would not have such fertile lands, and would not be able to grow all the products we need, vegetables and fruits, plants used in medicine and pharmacology.
Finally, we need to pay attention to the animal world, because it also could not exist without plants on Earth. The fact is that many animals, including wild ones, eat plants, being herbivores. That is, if there was no food for them on the planet, they would simply die out. However, plants also affect predatory animals, because they, in turn, feed on other representatives of the animal kingdom, which, as we have already said, would not exist without plants. Accordingly, extinction would also await predators.
This is why life on Earth is impossible without plants.

Plants are the first step in the food chain
Answer from Siatkoq Karomel[newbie]
Vegetation cover is also of great importance as a source of oxygen, without which life on Earth is impossible. Green plants release huge amounts of oxygen into the atmosphere.
One average-sized tree produces enough oxygen per day to breathe for three people. And how much does one hectare of forest produce, an entire forest area, all the forests of the globe!
Green plants play an extremely important role in one more respect: they, and only they, are capable of absorbing carbon dioxide from the atmosphere on a large scale and, therefore, preventing its accumulation in the atmosphere. air envelope of our planet. An increase in carbon dioxide in the Earth's atmosphere would have the most detrimental consequences.
Many examples can be given showing how great the role of vegetation is in the life of nature. Without the participation of vegetation, the process of soil formation is impossible - one of the most important processes occurring on Earth. Without plants, the life of wild animals is impossible - not only herbivores, but also predators. Vegetation cover prevents the erosion of river banks and mountain slopes, sand blowing, etc. Vegetation affects the atmosphere and soil, groundwater And animal world, streams and rivers, lakes and swamps. In other words, this is a powerful natural factor, the importance of which is difficult to overestimate.

Hello! Here is a selection of topics with answers to your question: Why is life on Earth impossible without plants?
Let's discuss it together
Question: “Without plants, life on Earth would be impossible. Man cannot live without plants." What evidence can be provided to confirm or refute these assumptions? Let's compare your answers with the text.
Answer: plants inhabited our planet long before people appeared on it. Since then, they have lived on a variety of land areas, sometimes poorly adapted for life. They grow in the tundra, forests, steppes, and deserts. They inhabit lakes, rivers, seas and oceans. Plants can be found even on bare rocks and shifting sands.
Plants are essential for human life, as they produce oxygen necessary for breathing; domestic and wild animals feed on plants.
Herbs, trees, and shrubs cover the ground with a dense living carpet, protecting it from drying out. In tree thickets a softer, humid microclimate is created, since the foliage does not allow hot sun rays dry up the earth. Their roots hold and hold the soil together.
Extremely important function green plants - the implementation of a biological process called photosynthesis. This process is extremely important for the existence of all life on this planet. Thanks to photosynthesis, plants have the ability to create organic substances from carbon dioxide and water that are necessary for plant products food - vegetables, fruits, grains, legumes, etc. Plants are also used as raw materials for industry, construction, and medicine.
The formation of the gas composition of the atmosphere is also directly dependent on plant life. Thanks to photosynthesis, plants release into the atmosphere a huge amount of oxygen necessary for all living things. They increase soil fertility thanks to humus. With their roots, they suck out some of the minerals from the soil, after which they pass them on to animals as food. Plants play a huge role in the life of nature, influencing climate formation, water sources, animal life, as well as other components of the biosphere.
Question: Explain why the forest is called “the lungs of the Earth.” Where is it easier to breathe: near a highway or in a meadow? Why?
Forests are called “the lungs of the Earth” because forests, being air purifiers from the main pollutant - carbon dioxide, absorb it from the atmosphere and produce oxygen necessary for the life of all life on Earth.
It’s easier to breathe in the meadow than near highways, because... cars passing over them emit a lot of harmful substances creating the so-called “air pollution”. Plants growing along highways absorb a small amount of harmful emissions, and accumulate them in their composition (leaves and fruits), so you cannot collect mushrooms and berries that can grow along the roads.
In meadows far from highways, there is no air pollution from automobile exhaust gases, plants produce oxygen, the air is clean and easy to breathe.
Question: Tell us which plants “feed” a person, which ones “treat”, which ones “dress”.
Answer: Plants that “feed” a person, those that can be eaten, there are a great many of them. To give an example, here are just a few: vegetable plants: tomatoes, cucumbers, cabbage, carrots, beets;
fruit trees: apple, pear, plum, orange and tangerine trees;
cereal plants from which we obtain cereals: semolina, buckwheat, rice, wheat flour;
There are also a lot of medicinal plants; dry tea mixtures, tinctures, ointments, and concentrates for making tablets are made from them. Let's give examples medicinal herbs and tree fruits: plantain, pink radiola, ginseng root, chamomile, sea buckthorn, calendula, raspberry, aloe;
Plants that “dress” a person include those from which fiber is made to make fabric. The main plants are flax and cotton. But fabrics can be obtained from bamboo, nettle (the fabric is called “ramie”), and jute.
Homework:
Question: Look at the pictures. On what basis can plants be divided into groups? Describe one of these groups.
Answer: *Plants will be correlated according to the following criteria: cultivated and wild
Cultivated plants: garlic, cauliflower, buckwheat, cotton, flax, sea buckthorn.
Wild plants: rose hips, chamomile, birch, oak, cedar pine.
