Human-Environment Interaction: Definition & Examples

Human-environment interaction refers to how humans impact Earth's ecosystems. Here's a full human-environment interaction definition and useful examples.

The term human-environment interaction describes the ways in which humans and their surrounding ecosystems influence each other. This relationship is bidirectional, for example: Humans modify their surroundings for their benefit, such as through deforestation to create farmland. Conversely, the environment shapes human behavior and innovations, like the necessity of warm clothing in colder climates.

Why Is It Important to Define Human-Environment Interactions?

Understanding the dynamics within human-environment interactions is integral to developing sustainable solutions to environmental issues. Human behavior has changed local ecosystems and had a tremendous effect. For example, human fire usage caused a major wave of extinction and ecological change during the Pleistocene Era. Identifying how our current actions could have similar impacts can help us change for the better.

On the flip side, creating a full human-environment interaction definition and understanding the effects of climate change can inform how we adapt to our new world. According to the World Meteorological Organization, there are five times as many extreme weather, climate, and water events as there were 50 years ago.

Nonetheless, deaths have decreased thanks to improvements in early alert programs, which were developed in response to human needs. As you can see, understanding how our changing planet affects us can help us plan for the future.

3 Types of Human-Environment Interaction

Let’s define the three major types of human-environment interaction. They are:

1. Dependence on the Environment: Humans depend on the world around us for basic needs like food, water, and shelter. In modern society, we also depend on other resources. Many of us rely on money or fossil fuels that often supply energy to our homes. For better or for worse, these dependencies shape how humans behave. They have a significant impact on the resources we seek and maintain.
2. Modification of the Environment: We modify the world around us to suit our needs, like building shelters to shield ourselves from the weather or clearing land for farming. These modifications can minimally impact nature and the surrounding environment, or they can be to being completely disruptive. For example, an innovative agricultural technique, vertical farming may offer a more ecologically friendly alternative to large-scale industrial farming. According to the UN, these conventional techniques are bad for the environment and promote animal and human diseases. Learning which modifications are environmentally harmful will help us create more sustainable alternatives.
3. Adaptation to the Environment: Humans have adapted to live in various environments, from the freezing arctic circle to blazing regions along the equator. Adaptation to nature can be both genetic and learned. Having darker skin is a genetic adaptation that might help an individual living in sunny environments, for example. In contrast, a learned adaptation that could have the same effect is creating garments that shield your skin from the sun. Developing new ways to adapt is vital for a sustainable future.

Of course, there is significant overlap between all three kinds of human-environment interaction. Our dependence on the environment impacts how we choose to modify it, and how we change the environment can be one of the ways we adapt to it.

While these categories are not set in stone, thinking of these different kinds of human-environment interactions is a helpful way of analyzing our relationship with nature. In the section below, you can read some practical human-environment interaction examples that have led to solutions for environmental issues.

Human-Environment Interaction: Examples

Climate change is a complex issue with no one-size-fits-all solution. But understanding the effects of human-environment interactions can often be the first step to developing more sustainable living methods. Analyses at a personal level can help us identifyhttps://www.pnas.org/doi/10.1073/pnas.1618138113behaviors that we need to change.

We can find an example of this in a PNAS study:

• Once scientists had observed the catastrophic effects of overfishing, different organizations began to take action to minimize or prevent future damage. Scientists found a solution by analyzing a particular instance of human-environment interaction: humans are dependent on marine resources, so by overfishing, they negatively impacted their environment.
• Once scientists analyzed this issue and identified the interactive relationships between humans and the marine environment, the problem became clear. Researchers could then focus on how to incentivize fisheries to stop overexploiting resources.

Crucially, analyses of human-environment interactions consider the various factors that the people involved depend on. Rather than directly focusing on how behavior affects the environment, the analysis considers the dependencies driving this behavior.

• For example, in the case of overfishing, the analysis considered not only a direct reliance on seafood within some communities but also commercialized fishing as a livelihood for countless individuals across the globe.
• Acknowledging these complex needs allowed scientists to identify the importance of economic and social incentives to reduce the amount of fishing. This allowed them to propose solutions that are not only environmentally responsible but could also protect the livelihoods of those currently employed in fishing industries.

Below, we’ll take a look at seven other examples of human-environment interactions that have benefitted or could benefit from a similar analysis.

7 More Examples of Human-Environment Interaction and Areas for Future Development

We’ve seen why a definition of human-environment interaction is important. Now, let’s take a closer look at some practical examples. 

1. Tourism on the Galapagos Islands: Many environmentalists have raised concerns over how increasing tourism has damaged the unique ecosystem in the Galapagos. But many local residents have been hesitant to support restrictions because they rely economically on the industry. Finding an environmental solution that allows residents to continue earning a living will be essential for solving this ecological issue.
2. Whaling in Japan: Japan’s whaling industry only employs a few hundred individuals today and barely contributes to the nation’s economy. But still, deep cultural ties have caused inertia against an anti-whaling stance, according to research from California State University. Acknowledging these cultural roots can allow researchers to develop better arguments for passing legislation for marine life conservation.
3. Oil, Gas, and Mining Industries: Extensive planning and risk assessment can prevent some of the most environmentally damaging industries from causing serious harm to surrounding ecosystems, including human communities. For example, scientists suggest that planning oil pipeline routes to avoid settlements and preserve nearby wildlife can minimize this industry’s harmful effects.
4. Balancing Land for Agricultural Use and Preservation: Governments often pass legislation to protect natural landscapes when they reach a critical point. But these protections are often removed once an ecosystem has sufficiently recovered. This leads communities to overexploit resources to a breaking point, then briefly protect them before overexploiting once more. Some scientists have proposed human-environment interaction definitions and models as a solution to discover and implement an equilibrium between human agricultural needs and protecting natural ecosystems.
5. Animal Consumption and Disease Regulation: The inhumane conditions in which livestock are kept and slaughtered are a concern of their own. But another issue with animal agriculture is its potential to create new disease outbreaks. Research analyzing human-animal interactions is, therefore, crucial to public health.
6. Greenhouse Gas Emissions: The increase in humanity’s contribution to greenhouse gas in the atmosphere has been linked to sudden climate change over the past 50 years. Recognizing these impacts of human behavior has sparked discussions about the importance of creating alternatives for industries that produce large amounts of greenhouse gases.
7. Overhunting: People may hunt to obtain food or to cull populations of predators such as wolves, which they consider a danger or nuisance to human communities. If done in excess, hunting can overthrow the delicate balance of an ecosystem, causing some species to overpopulate while others dwindle. An analysis of human-environment interactions can help us understand this balance and identify how much hunting is permissible, where necessary, before we reach a point where humans cause major damage to local wildlife.

Building a comprehensive human-environment interaction definition and examples will allow scientists to generate feasible solutions to pressing environmental issues. Sustainability, after all, entails a lifestyle that is good for the environment and that we can realistically sustain over long periods. Therefore, understanding how we interact with and rely on the environment will be very important for a brighter future.
