The problems facing our planet these days can seem overwhelming. The systems our modern society depends on—agriculture, industry, transportation—are polluting our air, water, and soil. Global warming is causing devastating heat waves, wildfires, droughts, and storms. Forests are disappearing, coral reefs are dying, and species all over the world are threatened. All this makes it harder than ever to provide water, energy, and food for our growing population.
But humanity also has a powerful new tool for dealing with these challenges: artificial intelligence, or AI. It can collect and analyze environmental data much faster than human scientists using older tools. And it can use this information to predict problems and find the best solutions.
The term “artificial intelligence” is a bit misleading. The most sophisticated machines we have today can’t really think or make decisions on their own (...yet). However, they can perform a variety of functions that would once have required a human brain. They can collect and analyze data, make predictions, and use language. They can also learn to do all these tasks better the more they practice.
Modern AI isn’t a replacement for human intelligence but a supplement to it. It can make humans much better at:
Artificial intelligence helps scientists gather and analyze all kinds of information about the environment. AI tools can help them monitor:
One reason climate change is such a difficult problem to deal with is that it’s hard to predict. However, artificial intelligence can make it easier. AI tools analyze historical climate and pollution data and also monitor current greenhouse gas levels, glacier mass, and sea level. For instance, Carbon Tracker combines AI with satellite imagery to track greenhouse gas emissions from fossil fuel power plants. AI can then process the vast amounts of data involved to model how all these factors are connected. This helps scientists determine how climate change affects ecosystems and human populations.
One of the most ambitious AI-based climate models is the European Commission’s Destination Earth (DestinE) project. This digital “twin” of the earth will model the changing climate as accurately as possible over time. In addition to mapping the planet’s past, DestinE will run simulations showing how it could change in the future. Governments will be able to use this information to develop better policies for both mitigating and adapting to climate change.
Artificial intelligence can also be useful in managing natural resources, such as forests, fisheries, and bodies of water. AI can analyze features of a landscape, such as plant cover and water flows, and detect problems like soil erosion. This helps people in the area address the problem and prevent further loss of natural resources. AI can also help us restore damaged landscapes, such as forests or coral reefs. It can identify the ideal variety of new species to add and the best places to put them.
One area in which AI is particularly helpful is forest management. For instance, a company called NCX has used AI to map out every acre of forest in the continental U.S. Having an accurate inventory helps landowners and foresters know which trees to cut and which to leave behind. AI tools also help forest managers perform “controlled burns” to remove excess brush that can fuel wildfires. Using AI, they can determine when weather conditions are ideal to set a fire without endangering nearby communities.
Another type of natural asset artificial intelligence can help manage is wildlife. Scientists can use AI programs to:
One example of an AI-driven platform used for conservation is Wildbook. It uses machine learning and computer vision to recognize and track the movements of individual animals based on photos and other data. This helps scientists keep track of population and migration patterns and develop strategies for conservation.
Another AI tool for protecting wildlife is Protection Assistant for Wildlife Security (PAWS). It employs machine learning to predict the behavior of poachers. Based on this information, it creates “risk maps” of an area and suggests patrol routes for rangers. In its first month of testing, PAWS enabled rangers to remove twice as many illegal snare traps as usual. The researchers behind PAWS are also working on an AI tool to map smuggling of animal parts. This will help authorities position checkpoints to catch illegal wildlife traders.
Two of the biggest environmental problems are plastic waste and emissions from burning fossil fuels. Artificial intelligence offers several ways to address these problems. It can assist with:
Artificial intelligence is a powerful tool for creating a cleaner environment. However, this revolutionary technology has great potential to be harmful as well as helpful. There are three major ethical concerns related to AI in environmental solutions: privacy, bias, and resource use.
One problem associated with AI is privacy. Training an AI requires huge amounts of data. If an AI learns from a data set that includes people’s personal information, what does it do with that information? Could anyone who uses the AI gain access to it? The answers aren’t always clear.
There’s even a risk that an AI could infer information it wasn’t actually given. It might be able to deduce an individual’s location or habits based on general data about that person.
One example of how this could play out in environmental applications relates to energy use. AI programs can help you save energy by keeping a record of your energy use at home or at work. But based on this data, the AI might be able to figure out details about your schedule and habits. It might even be able to identify you by name.
To deal with this problem, businesses and other organizations are working on ethical guidelines for training AI. Examples include the Partnership on AI, the United Nations' Multistakeholder Advisory Body on Artificial Intelligence, and tech companies like IBM.
You might think that bias is a human problem. Computers are machines that operate according to logical rules, so their judgments ought to be strictly impartial. But just like humans, AIs learn what they’re taught. If the data set used to train an AI is skewed in some way, the AI’s output will be similarly skewed or outright wrong.
Experts say countering bias in AI is a two-part process. The first step is to come up with ways of defining and measuring fairness. The second is to incorporate that definition into an AI’s decisions. This could be done either by making it part of the AI’s training or by using it to adjust the system’s output.
Ironically, the AI tools being used to help the environment also create environmental problems of their own. AIs that crunch huge amounts of data use vast amounts of computing power. The computers that run them consume lots of energy and require lots of water to keep them cool. Already, data centers use around 1% of all the world’s electricity and produce around 1% of total greenhouse gas emissions. By 2027, AI servers could consume as much energy as a small country.
Another problem is electronic waste, or e-waste, from the computers that run AI programs. This waste often contains toxic materials such as chromium and lead. Also, it requires rare materials, and generates e-waste. In 2021, the world’s e-waste totaled over 63 million tons—more than the mass of the Great Wall of China. This number will only grow as AI becomes more prevalent. And currently, only around 17% of e-waste is properly recycled.
The United Nations’ Coalition for Digital Environmental Sustainability (CODES) is working on ways to reduce AI’s environmental footprint. Changing the design of AI programs can reduce their energy use almost 90%. Solutions for reducing e-waste include making it easier to repair and recycle electronics.
Artificial intelligence is a fairly new technology, but it’s already transforming our approach to protecting our planet. AI helps us monitor the environment—air, water, wildlife—to detect and respond to problems. It can also create models to help us identify the best solutions.
In the future, AI could do even more. Artificial intelligence is growing more intelligent all the time, able to handle even bigger and more complicated sets of data. And the growing Internet of Things—physical devices linked to the Internet—will provide more data for it to use. This will make AI’s predictions more accurate and its solutions more useful.
The problems facing the planet are large and complex. But thanks to AI, we now have large and complex tools for tackling them.
