Technology's Pollution Problem: Cause Or Effect?

Technology has been a catalyst for positive global growth since the dawn of humanity. However, it has also had a negative impact on the environment, causing pollution and the depletion of natural resources. The production and use of technology can cause air, water, heat, and noise pollution, as well as the contamination of the food chain. The manufacturing of technology creates large amounts of waste, and the devices themselves often contain non-biodegradable materials and toxic chemicals that can leak into the ground and water supply if not disposed of properly. While technology has the potential to save the planet from these problems, it is important to consider the environmental cost of its production and use.

Technology and natural resource depletion

The production and use of technology contribute significantly to natural resource depletion. For instance, the manufacturing of electronic devices like computers requires a substantial amount of energy, fossil fuels, chemicals, and water. According to a United Nations University study, 81% of the energy a computer needs is consumed during its production, far exceeding the energy used during its operational lifetime. This high energy demand during production results in a significant initial energy output, even before the device is utilized by the end-user.

The depletion of natural resources has a direct impact on the environment and can lead to economic consequences. For example, freshwater resources are essential for life, and their depletion can cause a decline in agricultural productivity and fish populations. This, in turn, affects ecosystems and the economies that depend on them. Similarly, deforestation, driven in part by poverty and the need for charcoal as a cooking fuel, contributes to the depletion of forests, which provide ecosystem services valued at approximately $33 trillion annually and support the livelihoods of about a quarter of the world's population.

However, technology can also play a role in mitigating natural resource depletion. Precision agriculture, for instance, utilizes technology to optimize resource use, helping farmers reduce their consumption of fertilizer, pesticides, water, and other inputs. Additionally, advanced technologies like smart thermostats can help conserve energy by automatically turning appliances on and off as needed. Renewable energy technologies, such as those utilizing wind and sunlight, offer a sustainable alternative to finite fossil fuels and do not release greenhouse gases, addressing climate change concerns.

While technology has contributed to natural resource depletion, it also offers solutions. By promoting sustainable practices, utilizing renewable energy sources, and implementing innovative technologies, it is possible to reduce the depletion of natural resources and work towards preserving the environment and supporting economic growth.

Air pollution from technology

Technology and digitalisation are increasingly being used to combat air pollution. For example, smart technology is being used to monitor air quality and fight pollution in cities worldwide. The Clean Air Act in the US has helped to develop cleaner technologies such as smokestack scrubbers, catalytic converters, and low-VOC paints. Vehicle emissions standards are also being implemented to reduce tailpipe and evaporative emissions from passenger cars, light-duty trucks, medium-duty passenger vehicles, and some heavy-duty vehicles. These standards will reduce atmospheric levels of ozone, fine particles, nitrogen dioxide, and toxic pollution.

However, technology can also contribute to air pollution. The production and disposal of electronic devices can result in air pollution, as well as the release of carbon emissions from cars, airplanes, power plants, and factories. The energy needed to power data centres and devices also contributes to greenhouse gas emissions. The manufacturing processes for electronic components can expose workers to toxic substances and the extraction of raw materials for tech products can deplete natural resources and destroy habitats.

Electronic waste, or e-waste, is another source of air pollution. E-waste often contains toxic substances like lead, mercury, cadmium, and arsenic, which can leach into the soil and water if not properly disposed of. In 2019, the world generated an estimated 53.6 million tonnes of e-waste, but only a small fraction of it was properly recycled. The improper dismantling of electronic devices can release hazardous substances and pose health risks.

While technology has traditionally posed challenges to environmental sustainability, advancements are being made towards more eco-friendly technologies. Innovations such as renewable energy technologies, energy-efficient appliances, and biodegradable materials are helping to reduce the environmental impact. Additionally, technology plays a key role in waste management by enabling the implementation of automated sorting and waste separation systems, as well as stimulating research into new materials.

Water pollution from technology

Water pollution is the release of substances or energy into surface and subsurface waters, causing interference with the beneficial use of the water and the natural functioning of ecosystems. Technology has played a role in water pollution, both directly and indirectly.

One of the direct ways technology contributes to water pollution is through the improper disposal of electronic waste, or "technotrash." Electronic devices often contain non-biodegradable materials, heavy metals, and toxic substances that can leak into the ground and contaminate water sources. These toxins can have severe health impacts on humans, causing nausea, diarrhoea, vomiting, and even cancer.

Additionally, certain technologies and industrial processes can lead to the release of toxic chemicals and gases, which eventually find their way into water bodies. For example, nitrogen oxides and other gaseous emissions from industries and vehicles can contaminate water and boost the formation of algae. This excessive algae growth, known as algal blooms, blocks oxygen for aquatic life, creating "dead zones" where most aquatic species cannot survive.

The use of certain technologies can also indirectly contribute to water pollution. For instance, deforestation, driven by the expansion of cities and technological advancements, leads to soil erosion and the runoff of sediments into water bodies. Similarly, drilling activities, a technologically driven process, can result in waste that ends up polluting water sources.

Furthermore, technology has played a role in addressing water pollution through the development of innovative solutions. Artificial intelligence (AI), the Internet of Things (IoT), and big data are being leveraged to enhance water environment quality monitoring (WEQM) systems. These technologies improve digitalization, intelligence, and networking capabilities, aiding in the early detection and tracking of water pollution. Techniques like bioremediation use microorganisms to remove pollutants and decrease the toxicity of metals in water, mitigating the harmful effects of pollution.

While technology has contributed to water pollution, it also offers potential solutions. By utilizing innovative technologies and implementing better waste management practices, we can work towards reducing the impact of technology on water pollution and strive for a more sustainable future.
