World Environment Day and the Role of Vertical Farming and Hydroponics
World Environment Day is the biggest event for taking care of the Earth. Every year on June 5, people in over 150 countries join together to protect the planet.
This Global Environment Day, we’re finding smart ways to solve big problems. Vertical farming and hydroponics are two great examples. They grow food using less land and water, which helps the Earth and supports a cleaner, greener future.
What is World Environment Day?
World Environment Day is celebrated every June 5. It brings people together worldwide to take action for a cleaner, greener planet. The next sections will explore how this global event started and why it matters.
Why do we celebrate June 5 as World Environment Day?
This date has special meaning in the history of global environmental action. June 5th marks the start of the first major world meeting focused on the environment, the 1972 Stockholm Conference. This date was chosen to remind us that protecting nature requires global teamwork and action.
A Global Movement for the Planet
World Environment Day started at the Stockholm Conference in 1972, where world leaders talked about how to protect nature. The United Nations made it official in 1973.
Now, this Global Environment Day is celebrated in more than 150 countries. It helps people learn about the planet’s problems and encourages action to fix them.
What is the difference between Earth Day and Environment Day?
Both focus on the environment, but each has its own date, history, and goals.
Earth Day, held on April 22, began in the United States in 1970. It’s a grassroots movement encouraging people to get involved in local cleanup projects, plant trees, and push for stronger environmental laws.
World Environment Day is led by the United Nations and celebrated on June 5. It focuses on significant global issues like climate change, land restoration, and pollution. Each year has a theme, and countries worldwide participate through events, campaigns, and policy changes.
This Year’s Theme: Uniting to End Plastic Pollution
In 2025, World Environment Day will address one of the planet’s most pressing, and solvable, environmental issues: plastic pollution. The global event will be hosted by the Republic of Korea and serve as a rallying point for collective action and innovation.
Plastic waste has infiltrated every part of our lives — from the water we drink and the food we eat to the air we breathe and even our bodies. But while the scale of the problem is vast, the path forward is clear. We already have many of the tools and knowledge needed to fix it.
This year, World Environment Day joins forces with the United Nations Environment Programme’s #BeatPlasticPollution campaign. The goal? To inspire governments, businesses, and individuals worldwide to push for change. From reducing single-use plastics to rethinking our entire approach to consumption, the campaign urges us to refuse, reduce, reuse, recycle — and most importantly, to rethink.
The day will spotlight the latest science on the devastating effects of plastic pollution while reinforcing the momentum behind the global treaty agreed upon in 2022 to eliminate plastic waste. It’s not just a day of awareness — it’s an international call to action.
Why Agriculture is Central to Environmental Action
Agriculture is closely tied to our environment. It uses over 70% of the world’s freshwater and takes up large land areas. When farms use too much water, cut down forests, or rely on chemicals, it can damage the soil, pollute water, and harm nearby ecosystems.
But farming doesn’t have to hurt the planet. In fact, it can help heal it. Sustainable practices like hydroponics and vertical farming use fewer resources and avoid many of the problems caused by traditional methods. Emphasizing technology and thoughtful planning can position agriculture as a powerful way to fight climate change, protect land, and feed growing communities.
Understanding Vertical Farming and Hydroponics
Vertical farming and hydroponics are two methods that help grow food more sustainably.
Vertical farming means growing crops in layers, one on top of another. These farms can be indoors or outdoors, often in cities with limited space. They use technology to control factors like light, water, and temperature to grow food more efficiently.
Hydroponics grows plants without soil. Instead, the roots sit in water that’s mixed with nutrients. This system uses much less water than traditional farming, allowing plants to grow faster and healthier.
Both methods reduce the need for large plots of land and help protect natural resources like soil and water.
Environmental Benefits That Align with World Environment Day
Vertical farming and hydroponics offer measurable, practical benefits for the planet. These systems use fewer natural resources and create less waste, making them a strong match for the goals of World Environment Day.
In the next sections, we’ll look at how they save water, protect land, reduce pollution, and lower emissions.
Conserving Water in a Changing Climate
Water is one of our most important resources, and it's becoming harder to manage as the climate changes. Traditional farms use large amounts of water, much of which is lost through runoff or evaporation.
Hydroponic systems use 70–95% less water than soil-based farming. That’s because the water is recycled and reused with little loss. Aeroponics, a system where roots are misted with water, saves even more. For example, growing tomatoes traditionally might use 214 liters of water per kilogram, while hydroponics uses 70 liters, and aeroponics just 20.
These water-saving methods are especially important in areas facing drought and water shortages. They help ensure we can keep growing food without draining the planet’s water supply.
Restoring Land Through Efficient Land Use
Vertical farming allows growers to stack crops in layers so they can grow much more food in a smaller space. This high-yield approach is especially helpful in areas with limited or unusable farmland.
Because these systems don’t need healthy soil, they can grow food in places like deserts, rooftops, or urban buildings. This reduces the pressure to clear forests or damage natural ecosystems to create new farmland.
By making better use of space, vertical farms support World Environment Day’s focus on land restoration and fighting desertification. You can see how this works in practice in our high-yield greenhouses.

Reducing Chemical Pollution with Soilless Systems
One major benefit of hydroponic and vertical farming is that they don’t use soil. That means no soil-borne pests, so there’s little or no need for pesticides. These systems also use controlled environments, which help prevent plant diseases. As a result, farmers don’t need herbicides either.
Another big plus is how nutrients are delivered. In hydroponics, plants get exactly what they need, when they need it. This precision reduces fertilizer use and keeps extra nutrients from running off into nearby water.
Lowering the use of chemicals protects clean water and reduces pollution, making food production safer for people and the planet.
Lowering Emissions and Improving Local Food Security
Vertical farms and hydroponic systems are often located close to the people they serve. This local growing model means food doesn’t have to travel far, which helps cut down on fuel use and greenhouse gas emissions.
Because these systems don’t need tractors, plows, or deforestation, they also avoid the carbon footprint that comes with traditional farming. Even better, they can grow fresh produce all year long, no matter the weather.
That consistency makes food systems more stable, especially in areas hit hard by climate change. Growing food where it’s needed most improves access and reduces the risk of shortages.
Challenges and Opportunities for Impact
Vertical farming and hydroponics help solve many environmental problems, but they also face a few challenges. These include the cost of setup and the amount of energy needed. New tools and better technology turn these challenges into chances to do even more good.
Addressing Energy Use in Vertical Systems
Running a vertical farm requires a lot of energy. Lights, heating, and cooling systems help plants grow in the best conditions. If the power comes from non-renewable sources, this can mean increased energy bills and a larger carbon footprint.
To solve this, many farms are switching to energy-efficient LED lights. These lights use less power and still give plants what they need. Some farms also use solar panels and other clean energy to run their systems.
Even though energy use is a concern, vertical farming has strong benefits. These farms save water, protect land, and grow food close to where people live. With better energy solutions, the environmental impact can be even lower.
Overcoming Implementation Barriers with Innovation
Starting a vertical or hydroponic farm can be expensive. The equipment, lighting, and climate systems cost a lot up front. There’s also a learning curve, as many people need training to use the technology properly.
That’s where innovation plays a key role. Eden Green’s modular greenhouse systems help lower these barriers. Their plug-and-play design means less setup time and fewer technical frustrations. These systems are also built to fit different spaces and needs, making it easier for more communities to get started.
As technology improves, costs continue decreasing, and access keeps growing. What once seemed out of reach is becoming more practical and more common, even in schools, small towns, and local businesses.
The Future of Farming is Sustainable and Scalable
Modern farming methods like vertical farming and hydroponics don’t treat the problem with a temporary band-aid. They’re long-term solutions. These systems are built to grow with our planet's needs, making them key to a more sustainable future.
The next sections show how these practices support global goals and give communities new ways to lead the change.
Aligning with World Environment Day’s Long-Term Goals
Vertical farming and hydroponics help solve big problems that World Environment Day focuses on. They use less land and water, lower pollution, and avoid cutting down forests. These systems also help protect plants and animals by reducing the need for chemicals.
Since they don’t rely on weather or seasons, they can grow food in places where farming is hard. That makes food supplies stronger and more reliable, especially in areas hit by climate change.
These changes support the United Nations’ goals for a better world. At Eden Green, we focus on these values in everything we do. Eden Green’s mission is to build smart farms that benefit people and the planet.
How Retailers and Communities Can Lead the Change
Retailers are essential in shaping the future of food. With private-label hydroponic produce, they can reduce their environmental footprint while giving customers fresher, more sustainable options. This is a powerful way to support cleaner farming and show leadership in the market.
Communities can also get involved. Schools, nonprofits, and local groups can back controlled environment agriculture (CEA) projects to grow food closer to home. These efforts teach valuable skills, build stronger food systems, and reduce the need for long-distance shipping.
Everyone has a part to play, whether it’s choosing local greens at the store, starting a garden, or supporting policies that back sustainable farming. When people and businesses work together, real change becomes possible.
Keep the Momentum Going
World Environment Day reminds us that sustainable change is possible—and necessary. Vertical farming and hydroponics are clear examples of how smart solutions can support both people and the planet.
World Environment Day brings global attention to the need for environmental action. Vertical farming and hydroponics support that mission by using fewer resources, producing less waste, and growing food closer to where it’s needed.
