Plants are living multicellular organisms that grow from the soil with roots, stems and some kind of leaf structure. Plants create their own food (sugars) by converting sunlight into energy using chlorophyll, a green pigment. Through this process, they transform sugar from water and carbon dioxide. At the same time, they use sunlight and energy to release oxygen through photosynthesis.
With this process, plants are the foundation for many food chains and are vital for our survival and the health of the ecosystem. Apart from being an essential food provider, plants also shape and maintain the atmosphere, regulate water flow (through precipitation and transpiration) and regulate regional climates by absorbing carbon dioxide.
To sustain life, grow and reproduce, plants get nutrients from the air (carbon, oxygen, and hydrogen) and the soil (various minerals). Plants also need other important nutrients like phosphorus and sulfur. These are weathered from rocks where they are absorbed by plant roots or delivered to the plant by fungi and bacteria.
The underground connections with roots, fungi and microorganisms are fascinating and essential to all life. These connections are called mycorrhizae and function like a symbiotic arrangement and are an important set of survival mechanisms. Plant roots are hospitable sites for the fungi to anchor and produce their threads (hyphae). This connection through hyphae threads helps the plant absorb water and nutrients while the plant provides the fungi with sugars from photosynthesis as nutrients for growth. The functions of the roots help stabilize soil, preventing erosion and maintaining soil fertility.
Plants rely on pollinators, such as insects and birds, for reproduction, and in turn, they support these pollinators and other organisms in the ecosystem with food and also protection.
So, why are plants so important, and why do we have to make such huge efforts to protect plants and their diversity, particularly considering population growth and the need for more food and clothing?
From the air we breathe and the food we eat, we can hardly overstate the importance of plants.
Why are Plants so Important?
Habitat for all kind of wildlife.
Almost all animal life depends on plants in some way for its habitat. From rainforests to hedgerows and mangrove swamps to scrubland, plants and trees create an immense variety of habitats for all wildlife. Native trees like oak and birch play a particularly vital role in preserving biodiversity, ensuring that our ecosystems remain vibrant and resilient.
Regulate Climate
Plants are the best allies in the ongoing struggle against a warmer climate. Through the amazing process of photosynthesis, trees and plants absorb carbon dioxide and release life-giving oxygen, helping to regulate our planet’s climate and temperature.
Green Spaces and well being for humans
Nature (we are all a part of nature) can make you feel restored and in balance. Take a stroll, bike or jog through any park or woodland, and you’ll soon discover the calming power that feeds your soul and body.
Air Purifiers and oxygen production
In buzzing urban places, plants serve as nature’s air purifiers, filtering out environmental pollutants and toxins. Trees, in particular, act as guardians of our air quality, absorbing carbon dioxide, nitrogen dioxide and sulphur dioxide while releasing fresh oxygen.
Plants, pollinators, our food supply and medisin
Where would we be without pollinators like bees, butterflies and birds? Without them, we would not last very long! Just as plants need pollinators to reproduce, pollinators also need plants for their food and shelter. By planting native wildflowers, we create a pollinator-friendly habitat, and we support these tireless workers and safeguard the food supply.
Prevent flooding and erosion
Underground, the roots of trees and plants keep the soil together, protecting it from erosion caused by wind and rain. In regions prone to erosion, plant life plays an essential role in preserving fertile land and preventing landslides. Keeping the trees and plants healthy strengthens our soil, helps prevent flooding, and protects livelihoods.
Plants for textiles, timber and paper
Plants can be very versatile. Bamboo is one, and we use it in textiles, timber, paper and food. In textile production, we utilise various plants, their different parts, and plant waste. We also use mushrooms, lichens and algae for textiles and dyeing. Recently, natural alternatives to synthetic materials have gained more attention, including the use of various plants, fruits, and plant parts to create new fibres. Some examples include banana leaves, cacti, orange peels, pineapple, and mushrooms. Traditional textile-making techniques from the past are also rediscovered and utilised.
More plants, richer ecosystem
In a nutshell, the greater the diversity of plant and animal life in an ecosystem, the healthier and more resilient the ecosystem is. A vast diversity of plant life sustains a rich tapestry of ecosystems, including unique flora and fauna. In the UK, ancient woodlands support more species than any other land-based habitat, so protecting the woods we already have is as critical as planting more trees.
Protecting plants, especially trees and woodland species, is crucial for our future.
How can you get engaged?
- Get involved in planting more trees.
- Start a school program or volunteer with an existing organisation.
- Inspire others and talk about the importance of native plants and wildflowers.
