Role of plants in combating climate change

Role of plants in combating climate change:

Climate change is one of the major problem across the globe now a days to cope with climate change nature itself is providing a way.Plants, often overlooked in climate conversations, play a crucial role in mitigating environmental impacts.Plants help us to reduce the the amount of carbon in the environment which is one of the major cause of climate change besides this these plants also protect soil and support biodiversity.This blog explores the remarkable ways specific plants contribute to climate change mitigation. From towering redwoods that sequester carbon to versatile seaweeds that absorb oceanic CO2, we'll delve into how these green warriors support a healthier planet.

Trees

Redwood tree:

Coast redwood trees can clean more carbon from the air and store it longer than any other tree.

Coast redwood trees also play an important role in the water cycle helping to capture water from rain, and even fog, and trickle it down to streams where their roots help to trap sediment and improve water quality.

Through the process of photosynthesis, redwood trees transform carbon dioxide-the leading cause of accelerating climate change-into the oxygen we breathe.

Redwood forests are crucial in providing a healthy, stable climate. Studies show that coast redwoods capture more carbon dioxide (CO2) from our cars, trucks, and power plants than any other tree on Earth. Through the process of photosynthesis, redwood trees transform carbon dioxide-the leading cause of accelerating climate change-into the oxygen we breathe.

When redwoods are cut down, burned, or degraded by human actions, they release their stored carbon back into the atmosphere much faster. And, they can no longer transform CO2 into the oxygen we breathe. This has twice the impact for the growing imbalance in the world's carbon cycle and the climate's stability. Deforestation and other destructive land use account for nearly 25% of carbon dioxide emissions around the world.

And, as the climate changes, the redwood forests in the Santa Cruz mountains are one of very few areas in the region that can provide a refuge for plants and animals to adapt, because the area has many microclimates, is cooled by coastal summertime fog, and is still largely unpaved.

But this region-once a safe haven-is increasingly at risk.

Maple tree:

Maple forests not only support rich biodiversity but also play a crucial role in fighting climate change by serving as carbon sinks.

As the trees grow, they capture carbon dioxide from the atmosphere and store it in their trunks and roots as well as the surrounding soil.

Maples absorb carbon dioxide (CO₂) from the atmosphere during photosynthesis and store it in their biomass (leaves, wood, and roots). This helps reduce the amount of CO₂, a major greenhouse gas, in the atmosphere.

 Maple trees provide shade and release moisture into the air through transpiration, which helps cool the surrounding environment. This cooling effect can mitigate the urban heat island effect and reduce the need for air conditioning, further lowering energy consumption and emissions.

 The leaves and organic matter from maple trees improve soil structure and fertility. Healthy soils can store more carbon and support diverse plant life, which contributes to overall ecosystem resilience against climate change.

 Maples provide habitat and food for various wildlife species, including pollinators and birds. By supporting biodiversity, maples help maintain ecological balance, which is crucial for adapting to changing climate conditions.

The root systems of maples help prevent soil erosion and manage water runoff, which can mitigate the impacts of flooding and water quality issues exacerbated by climate change.

Incorporating more maple trees into urban and rural landscapes can enhance these benefits and contribute to broader climate change mitigation efforts.

Role of legumes:

Moreover, legumes play a role in conserving/fixing the nitrogen in the soil. Grain legumes serve the ecosystem by fixing nitrogen, and they also have deep root systems that help to reduce soil erosion.

 Legumes have the unique ability to fix atmospheric nitrogen into the soil, which reduces the need for synthetic fertilizers. This process lowers greenhouse gas emissions associated with fertilizer production and application.

By enhancing soil fertility and structure, legumes improve soil carbon storage. Healthier soils can sequester more carbon, mitigating atmospheric CO2 levels.

Including legumes in crop rotation systems can improve overall farm productivity and reduce reliance on chemical inputs, which further lowers greenhouse gas emissions.

 Legumes often require less water and energy compared to other crops, reducing the overall carbon footprint of agricultural practice. 

Legumes contribute to sustainable farming practices by promoting biodiversity and reducing soil erosion, both of which are beneficial for climate resilience.

By integrating legumes into agricultural systems, we can enhance soil health, reduce emissions, and support more sustainable food production practices.

Switch grasses role :

Also, perennial grasses such as switchgrass can deposit organic matter deep within the soil profile as roots expand into the subsoil for nutrients and water. Sequestration of carbon in soils removes CO2 from the atmosphere, which is considered a greenhouse gas contributing to global climate change.

Planting Switch Grass isn't just a garden choice; it's a climate statement. As a robust perennial, it stands as a low-tech, yet effective, tool in the battle against climate change. Its growth displaces carbon-heavy alternatives like traditional lawns, and when used in biofuel production, it offers a renewable energy source that further slashes carbon emissions. This grass isn't just green in color-it's green for the planet.

Switch Grass is a carbon sink superhero. Its deep roots and dense foliage work tirelessly, pulling carbon dioxide from the air and locking it away in the soil. This process, known as carbon sequestration, is a natural way of reducing greenhouse gases, the culprits behind global warming.

Switch Grass is a wildlife magnet. Its towering presence offers shelter and nesting opportunities for birds and small mammals. Pollinators, including bees and butterflies, are drawn to its blooms, creating a hub of activity in your garden.

Sea weed role:

Seaweed, which requires almost no land, water, or greenhouse gases to grow, can also pull carbon out of the atmosphere and act as a sustainable substitute for carbon- intensive products like plastic.

Seaweed can also help mitigate climate change by replacing carbon-intensive products. A report recently published by TNC and Bain & Company identified bioplastics and biostimulants as two of the most promising markets to drive demand while simultaneously reducing greenhouse gas emissions. Traditional plastics are derived from petroleum and never decompose, instead breaking down into smaller and smaller pieces that pollute our air and waterways, harm wildlife, and infiltrate our food supply. In contrast, bioplastics typically require fewer emissions to produce and are biodegradable. While some bioplastic materials require inputs like land, freshwater, and fertilizer to grow, seaweed doesn't, making it among the most sustainable bioplastic options.

Similarly, biostimulants (materials that improve terrestrial crop yields and health, nutrient uptake, stress tolerance, and soil quality) derived from seaweed can act as a substitute for less sustainable inputs. In rice field trials, seaweed biostimulants provided the same benefits as chemical fertilizers while generating only about half the carbon emissions per application. There is significant room for growth in this market; by some estimates, only about .5% of global farmland is treated with seaweed biostimulants. Increasing that to 3% of global farmland would boost demand for farmed seaweed to 3 million tons annually and potentially avoid up to 0.75 megatons of carbon emissions per year.

However, there currently isn't enough demand for seaweed products to support target growth. While both bioplastics and biostimulants could deliver climate and ecosystem benefits, seaweed is often more expensive than traditional products and competing green alternatives. Currently, there is a need to either justify a higher price by differentiating seaweed as a premium product or to lower the price through greater efficiencies, improved processing technology, or subsidies.

Impact of climate change on environment:

Climate change is effecting the environment in various ways as follows:

Weather change

As global temperatures climb, widespread shifts in weather systems occur, making events like droughts, hurricanes, and floods more intense and unpredictable. Extreme weather events that may have hit just once in our grandparents' lifetimes are becoming more common in ours. However, not every place will experience the same effects: Climate change may cause severe drought in one region while making floods more likely in another.

Already, the planet has warmed 1.1 degrees Celsius (1.9 degrees Fahrenheit) since the preindustrial era began 250 years ago, according to the Intergovernmental Panel on Climate Change (IPCC). And scientists warn it could reach a worst-case scenario of 4 degrees Celsius (7.2 degrees Fahrenheit) by 2100 if we fail to tackle the causes of climate change-namely, the burning of fossil fuels (coal, oil, and gas).

Higher average temperatures

This change in global average temperature-seemingly small but consequential and climbing-means that, each summer, we are likely to experience increasingly sweltering heat waves. Even local news meteorologists are starting to connect strings of record-breaking days to new long-term trends, which are especially problematic in regions where infrastructure and housing have not been built with intensifying heat in mind. And heat waves aren't just uncomfortable-they're the leading cause of weather change. 

Longer-lasting droughts

Hotter temperatures increase the rate at which water evaporates from the air, leading to more severe and pervasive droughts. Already, climate change has pushed the American West into a severe "megadrought"-the driest 22- year stretch recorded in at least 1,200 years-shrinking drinking water supplies, withering crops, and making forests more susceptible to insect infestations. Drought can also create a positive feedback loop in which drier soil and less plant cover cause even faster evaporation.

More intense wildfires

This drier, hotter climate also creates conditions that fuel more vicious wildfire seasons-with fires that spread faster and burn longer-putting millions of additional lives and homes at risk. The number of large wildfires doubled between 1984 and 2015 in the western United States. And in California alone, the annual area burned by wildfires increased 500 percent between 1972 and 2018.

Stronger storms

Warmer air also holds more moisture, making tropical cyclones wetter, stronger, and more capable of rapidly intensifying. In the latest report from the IPCC, scientists found that daily rainfall during extreme precipitation events would increase by about 7 percent for each degree Celsius of global warming, increasing the dangers of flooding. The frequency of severe Category 4 and 5 hurricanes is also expected to increase. In 2017, Hurricane Harvey, a devastating Category 4 storm, dumped a record 275 trillion pounds of rain and resulted in dozens of deaths in the Houston area.

Flooding

In addition to coastal flooding caused by sea level rise, climate change influences the factors that result in inland and urban flooding: snowmelt and heavy rain. As global warming continues to both exacerbate sea level rise and extreme weather, our nation's floodplains are expected to grow by approximately 45 percent by 2100. In 2022, deadly flooding in Pakistan- which inundated as much as a third of the country-resulted from torrential rains mixed with melting glaciers and snow.

These are major disaster cause by climate change to our environment besides these the climate change is disturbing the food chain across the globe, effecting soil health lead to melting of glacier all across the globe. To cope with these changes we have to do as much as we can to protect our environment for next generation. 

Plants can help us in combating climate change as their role in mitigating climate change is discussed above so by planting these trees or growing these crops or weed we can reduce the amount of carbon emissions in the environment and prevent more climate change. Which is going to take place in coming years if carbon emissions rate is not decreased. 

Besides growing these plants we should help these plants in their sustainability by providing them appropriate conditions for their growth and development. So they can provide numerous benefits to our environment.And help us in creating a healthy environment for next generations.
