Answer from Samwella[guru]
because plants produce oxygen, animals feed on them and give fruit to people.

Answer from Milena Marlowe.[guru]
Oxygen and photosynthesis are needed, plants produce oxygen.

Answer from Anastasia Serebryakova[newbie]
Plants are the first step in the food chain

Answer from Siatkoq Karomel[newbie]
The 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 medium-sized tree releases as much oxygen per day as three people need to breathe. And how much is allocated by one hectare of forest, a whole forest, all the forests of the world!
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, consequently, preventing its accumulation in the air envelope of our planet. An increase in the content of carbon dioxide in the Earth's atmosphere would have the most disastrous consequences.
Many examples can be cited to show how important the role of vegetation in the life of nature is. Without the participation of vegetation, the process of soil formation is impossible - one of the most important processes taking place on Earth. Without plants, the life of wild animals is impossible - not only herbivorous, but also predatory. Vegetation cover prevents the erosion of river banks and mountain slopes, sand flapping, etc. Vegetation affects the atmosphere and soil, groundwater and wildlife, streams and rivers, lakes and swamps. In other words, it is a powerful natural factor, the importance of which can hardly be overestimated.

The value of plants in nature and human life. As we know, all humans and animals breathe oxygen and emit carbon dioxide. The amount of carbon dioxide in the air also increases from fuel combustion. Plants, in turn, absorb carbon dioxide from the air in the light and release oxygen.

In addition, plants enrich the air with oxygen, reducing the amount of carbon dioxide. Due to the fact that oxygen is a necessary component for the life of people and animals, life on Earth without green plants would be impossible.

To enrich cities and villages with oxygen - avenues, boulevards, streets, etc. greening. People plant trees, shrubs, equip parks, boulevards, flower beds, lawns. In general, in any city on the planet, they try to plant as many plants as possible, which are so necessary to preserve the health of the population. Given that plants absorb carbon dioxide, they also release oxygen and some gaseous substances into the air, which trap dust and destroy harmful microbes.

Therefore, we must take care of the protection of our plants, each leaf and multiply green spaces, or rather, do not forget to plant new plants, take care of them, and protect them from damage.

The importance of plants in the formation of organic substances in them also plays an important role. Green plants create organic matter, and people and animals get them ready for their nutrition from green plants. People grow cultivated plants in order to further harvest fruits, vegetables, grains, etc. and eat them, prepare them for the winter. And for farm animals, grain and silage are collected, which are also necessary for the life of animals, because they contain nutrient organic substances. Animals could not exist without green plants, since they feed on ready-made organic substances that are formed in them.

Large meadows also contain many beneficial organic substances that are used as livestock feed. To do this, cattle are driven to pastures or they are mowing grasses and collecting hay. But mowing must be done at the very beginning of the flowering of grasses, because at this time the plants contain the most juicy nutrients. If mowing is done during flowering or fruiting, the grasses become coarser, and their nutritional quality is significantly reduced.

As a result, we can say that the importance of plants in nature and human life plays a very important role. Because green plants provide people with food, raw materials for industry, as well as feed for farm animals.

Hey! Here is a selection of topics with answers to your question: Why is life on Earth impossible without plants?

The plant world, or the flora of the Earth - a collection of all types of nuclear, multicellular, photosynthetic plants found in. Most of the organisms are those that synthesize their food with the help of solar energy, but there are also heterotrophic plants and very few species that are both autotrophs and heterotrophs. The history of life on Earth and the existence of many organisms literally depend on plant life. Since animals cannot receive energy directly from the sun, they must eat plants (or other animals that have a herbivorous diet) in order to survive. Plants also provide oxygen to humans and animals because they absorb carbon dioxide in and release oxygen into the atmosphere.

Diversity of the flora

Plants are common on land, oceans and fresh water. They have existed on our planet for millions of years. The number of species of currently existing green plants is presented in the following table:

The table shows the total number of different types of green plants ( Viridiplantae). It is estimated that there are about 300,000 living species Viridiplantae, of which 85-90% are flowering plants. (Note from the author: since the data are taken from different sources and have different dates, in some cases the calculations are subject to some uncertainty)

Differences between plants and animals

Australia

Eucalyptus regal

The flora of Australia is characterized by the presence of a large number of endemic species - plants that are not found anywhere else. Nevertheless, with the advent of settlers, many other "non-native" species have taken root on the mainland. Australian vegetation is characterized by a predominance of two types of plants - eucalyptus and acacias.

Asia

Asia has the greatest diversity of flora of all parts of the world, since it occupies the largest area, is located in various climatic zones and natural zones. Here you can find more than 100 thousand species of plants, from tropical to arctic, which is about 40% of the flora of the Earth. The mainland also has a large number of endemic plants.

Antarctica

Colobantus quito

Antarctica is the most inhospitable place on Earth, both for and for plants. There are no trees, only two types of flowering plants and a lot of mosses, lichens, algae, etc. the mainland is very fragile and suffers from climate change and human activities.

Africa

Spurge thorn

Africa is the second largest continent in the world and is home to many unique plants. The flora of the continent is divided into three main ones -, and. At the same time, they do not have a wide species diversity, because this biome is characterized by difficult climatic conditions, including high temperatures and droughts. The Sahara Desert, located in northern Africa, is one of the driest places on Earth. However, African humid evergreens contain a wide variety of plants.

Europe

Despite the fact that Europe is on the same continent with Asia, called Eurasia, there is no such rich species diversity of the flora as that of its eastern neighbor. The flora of Europe was largely influenced by the Alps mountain range, which stretches from west to east.

North America

North America is home to the planet's major biomes, from deserts to arctic tundras. Each biome is characterized by a collection of certain plant species that have adapted to growth in certain environmental conditions.

South America

South America, like Asia, has become home to a huge variety of plant species. Here is a huge ecosystem that supports the life of many and plants.

The value of the plant kingdom

The importance of plants in human life

Plants serve as the foundation of all life on earth and are essential for the well-being of humans. Think about how your daily life depends on plants.

• Air: Oxygen comes to us from plants as a by-product of photosynthesis.
• Food: Everything we eat comes directly or indirectly from plants. Throughout human history, approximately 7,000 different plant species have been used as food by humans.
• Water: plants regulate - they help distribute and cleanse. They also participate in the movement of water in a process called transpiration.
• Medicines: one quarter of all prescription drugs come directly from plants or are derived from them. In addition, four out of five people worldwide today rely on primary health care facilities.
• Vitamins: Plants are the largest source of vitamins necessary for the human body.
• Clothing: Plants are a major source of raw materials for textile materials.
• Culture: images of some plants are used in national emblems, including trees and flowers.
• Furniture and housing: the wood of plants is used in the construction of houses, as well as for the manufacture of furniture.
• Aesthetic pleasure: the presence of plants in people's lives allows them to enjoy their appearance and relieves stress. Therefore, many people grow ornamental plants in their homes and backyards.

The value of plants in nature

Amazon rainforest

The environment and climate are closely related to flora. The presence of precipitation, humidity and temperature depends on the presence and nature of the vegetation. The reduction of plants also upsets the balance in and indirectly affects human life.

• Food chains: In every food chain, plants are at their base and lead the chain as a food source. For example: Grass → Cow → Lion; Grass → Insect → Frog → Snake → Eagle. Here the plant starts the chain and other animals depend on it directly or indirectly. There can be no life on Earth without plants.
• Habitat: Of course, besides the huge number of people, plants form the basis of all habitats.
• Climate: Plants store carbon, which is released into the atmosphere when burned.
• Soil erosion: Plants growing in the soil, in sufficient quantities, prevent wind erosion (when in times of wind, the fertile topsoil is carried away by the air).
• Ecological balance: plants help reduce heat and prevent moisture from evaporating. Thus, they are environmentally beneficial.
• Precipitation support: plants and trees have a cooling effect on the atmosphere, leading to precipitation. Therefore, rains in deserts are extremely rare.
• Soil fertility: plants maintain soil fertility. Fallen leaves, fruits, etc., rot in the soil and humus is formed, which in turn increases soil fertility, as it is favorable for microorganisms.
• Habitat: Plants are the best habitats for birds and animals, including monkeys, squirrels, etc. Birds build their nests in trees for egg laying, sleeping, hunting and safety. In forests, animals can take shelter under trees in extreme heat and rain. They also provide food for many (earthworms), insects, rodents, etc.

Threats of the plant world

Deforestation

There are a huge number of flora species on our planet, both registered and not studied or even named. However, while the threat to the existence of many wildlife is now widely recognized, few people know that plants are also at great risk. In February 2015, the Center for Biological Diversity stated: “Of the more than 300,000 known plant species, IUCN has assessed only 12,914 species, finding that about 68% of the assessed plant species are endangered.”

The vast areas of deserts around the world testify to the destruction of vegetation by humans. Much of the Middle East is now desert or renewable for a lot of money. Once in the Mediterranean there were many forests, now these lands are bare and eroded. In many parts of Africa and India, cattle and goats roam the rocky plains, eating any patch of green that appears in the badlands that were once good pastures. Overgrazing by domestic and wild animals is, in fact, the greatest threat to plants, although botanists and other enthusiasts 'raids' on some beautiful plants sometimes entail serious losses for rare species.

Perhaps people forget that all of our cultivated plants and garden flowers come from wild flora. Equally important is the fact that plants provide a high proportion of medicines in the modern world. Who knows what secret treasures for humanity are still locked among the vegetation awaiting discovery. Tropical rainforests are among the most vulnerable habitats on the planet, containing 63% of endangered plant species.

One of the greatest threats to flora is the transformation of natural habitats into areas for agricultural and livestock use, for example, when rainforests are destroyed for grazing or growing soybeans, animal feed, or oil palms. Ancient woodlands are special because they have been around for at least 400 years and are the backbone of biodiversity and also support abundant wildlife.

Plant protection

Plant protection - a set of measures aimed at protecting existing plants and especially endangered species. The main document listing the plants to be protected is the IUCN Red List (International Union for Conservation of Nature).

The IUCN Red List is set against clear criteria for assessing the extinction risks of thousands of species and subspecies. These criteria are relevant for all species and regions of the world. The aim is to communicate the relevance of conservation issues to the public and governments of countries, as well as to help the international community try to reduce the extinction of species. According to the IUCN, the officially articulated goals of the Red List are to:

• provide scientifically sound information on the status of species and subspecies at the global level;
• pay attention to the scale and importance of the endangered flora;
• to influence national and international politics and decision-making;
• provide information for possible actions for plant conservation.

One of the most important protective actions is the creation of national parks, wildlife sanctuaries, nature reserves, botanical gardens, etc. These conservation sites help preserve the natural habitat of plants and protect them from over-exploitation by humans.
