At its core, environmental sustainability is about maintaining the natural systems that support life — both now and for future generations. It means using resources in a way that doesn’t deplete them, managing waste responsibly and balancing economic and social progress with care for the environment. So, how can individuals and industries work toward a more balanced future? We spoke with a Grand Canyon University natural sciences professor to explore these questions and share practical advice for students ready to make a difference.

In an age where climate headlines are the norm and terms like "carbon footprint" and "zero waste" are part of daily conversation, it’s clear that environmental sustainability isn’t just a buzzword — it’s a global priority. But what exactly is environmental sustainability and why is it something college students should pay attention to? Why is environmental sustainability important? Discover the answer to what is environmental sustainability and how GCU’s MS in Sustainability degree can prepare you to lead positive change.

Examples of Environmental Sustainability

Sustainability is everywhere these days — in the news, in classrooms and even in the way our favorite brands market their products.

As Nathan Glover, a natural science faculty member at Grand Canyon University, puts it: "Sustainability means using Earth’s natural resources to meet current needs without compromising future generations. It requires thoughtful decisions that reduce waste, pollution and harm to ecosystems — and it’s about living within the planet’s ecological limits."

According to Glover, the three pillars of sustainability — environmental, social and economic — work together to support ecosystems, equity and economic health. He adds, “True sustainability balances all three without sacrificing one for another.”

From major corporations to small towns, sustainability is gaining traction. Explore practical examples of environmental sustainability and see how leading companies are putting these principles into action.

Patagonia: The outdoor clothing company reinvests in environmental activism and uses recycled materials. They donate 1% of sales to environmental causes, giving over $140 million to grassroots groups worldwide since 1985.¹
Boulder, Colorado: Through bold climate policies, grassroots campaigns and cross-sector programs — from the nation’s first carbon tax to regenerative agriculture and zero-waste initiatives, Colorado leads in sustainability.²
Unilever: This global brand set aggressive waste and emissions targets, proving that sustainability and profitability can go hand in hand. Their 2030 goals include a 30.3% reduction in forest, land and agriculture emissions.³

“The success of these corporations shows how values-driven leadership can drive sustainable change,” says Glover. “Businesses can begin small with energy-efficient lighting, waste reduction and local sourcing, which are often backed by grants, tax incentives and partnerships. Even small changes can reduce costs and build brand loyalty.”

Why Is Environmental Sustainability Important?

“Environmental sustainability is important because both individuals and businesses rely on natural resources to function and survive,” explains Glover. “When we act irresponsibly, we degrade the systems that support our health, economies and future. Sustainable practices create long-term resilience and cost savings.”

"Climate change, biodiversity loss, water scarcity and plastic pollution are among the most pressing sustainability issues. These challenges threaten global stability, food systems and public health. Each of them is interconnected and demands urgent and coordinated action."

— Nathan Glover, Faculty

Without sustainable action, problems can spread through many parts of society. The economy may become less stable and unfair conditions can grow worse — especially for communities that are already struggling. Combating sustainability issues can offer a path toward greater equity, innovation and long-term stability — benefiting both current and future generations. “Our science programs and our sustainability master’s degree aim to overcome these struggles by preparing students to solve real environmental challenges through science, policy and hands-on experience,” says Glover.

The Role of Innovation in Promoting Sustainable Development

New technology is playing a huge role in building a more sustainable future. Innovations like:

Solar panels and wind turbines
Vertical farming
Biodegradable packaging
Electric public transport

These tools help reduce dependence on limited resources and minimize harmful impacts. But innovation isn’t just about tech — it’s also about new ways of thinking, like designing circular economies or redefining what growth means.

How Can Students Get Involved?

"What gives me hope is the creativity and drive of my students — they’re ready to make a real difference."

— Nathan Glover, Faculty

The best part about sustainability is that you don’t need to major in environmental science to contribute. Glover shares some simple ways you can get started:

Be mindful of waste: Reduce, reuse and recycle.
Cut back on single-use plastics: Carry a reusable bottle and say no to straws.
Support sustainable brands: Look for ethical sourcing and low-impact packaging.
Get informed and speak up: Join clubs, vote in local elections and advocate for campus sustainability efforts.

“As a GCU student, you can get involved through hands-on projects like a student-led community garden, where you study sustainable agriculture, composting and local food systems while promoting environmental stewardship on campus,” says Glover. With new degree programs in sustainability, there are growing opportunities to turn your passion into action.

Environmental Science Education: Preparing Future Sustainability Leaders

Sustainability isn't just a trend — it’s a mindset. One that asks: How can we live well today without compromising tomorrow? Whether you're studying business, art, biology or anything in between, thinking sustainably can add value to your education and your future.

At GCU, we teach these concepts through case studies, simulations and interdisciplinary coursework that shows students how practical systems function. Our courses focus on both the science and the ethics of sustainable development.

— Nathan Glover, Faculty

Pursuing an education in environmental science can be a powerful step toward creating a more sustainable world. A BS in Environmental Science or an MS in Sustainability prepares future eco-conscious leaders with the knowledge and skills to address environmental challenges through impactful careers, such as:

Sustainability specialist
Sustainability consultant or coordinator
Sustainability design coordinator
Compliance officer
Environmental science and protection tech
Environmental scientist and specialist
Forest and conservation technician

Glover adds, “Advancements like battery storage, carbon capture and AI-driven resource management are shaping the future — but education is still the most important thing we can do.”

Empower Change: Earn a Degree and Lead the Way to Sustainability

A common phrase in the sustainability field was coined by Anne Marie Bonneau, the Zero-Waste Chef. She said, “Sustainability isn’t one person doing everything perfectly — it’s millions of people making better choices every day.”⁴This idea reflects a growing belief that widespread, imperfect action is more powerful than isolated perfection. When many people take small, consistent steps, the collective impact can lead to real, lasting environmental change.

One way to join this impactful movement is to earn a bachelor's degree in environmental science. With a solid foundation in environmental principles, you can be equipped to make informed decisions, drive meaningful change and contribute to the global effort of sustainability in ways that align with your values. Consider joining this movement by earning a sustainability or environmental degree from GCU.
