Ch 2: Artificial Intelligence and Its Applications Class 8 Notes
Introduction
Artificial Intelligence is making our lives better, faster, and more efficient. AI helps us to make better decisions. Have you ever thought about how your phone knows what you say, how online games change their difficulty based on your skill level? It is AI that actually works behind the scenes.
Key Area of AI where it is making a significant impact:
- Environment
- Automation
- Healthcare
- Education
AI for Environmental Problem Solving
Common environmental issues are
- Plastic Pollution
- Air Quality Problems
- Waste Management Challenges
- Wildlife loss
- Soil Degradation
Let us discuss these in detail
1. Plastic Pollution
Plastic pollution is among the direct environmental threats facing the world. India generates nearly 3.5million tonnes of plastic waste every year, half of which enters rivers and oceans. Plastics basically do not biodegrade but break down into the micro plastics, which enter the food chain and are found in foods that we eat.
How AI Helps to reduce Plastic Pollution?
AI can play a significant role in reducing the plastic pollution. AI systems can analyse satellite images to detect the areas where plastic waste is dumped. In 2023, 70 plastic dumps were identified in Himachal Pradesh by the Department of Environment Science and Technology (DEST). This helps authorities to take faster action to remove the waste.
2. Air Quality Problem
In many cities, the air contains harmful pollutants from vehicles, factories, and the burning of crop stubble in nearby agricultural areas. Poor air quality affects everyone, but children and the elderly are particularly at risk. It can cause breathing difficulties, trigger asthma attacks, neurological and immune system disorders
How AI Helps to improve Air Quality?
AI systems can analyse data from air quality monitoring stations and combining this with weather data, AI can predict when and where air pollution will increase. This allows authorities to take preventive measures, such as:
- Advising schools to cancel outdoor activities
- Alerting hospitals to prepare for more patients with breathing problems
- Temporarily restricting vehicles in highly polluted areas
The first air quality monitoring and early warning system was launched in Ahmedabad, Gujarat, in May 2017 by the Ministry of Earth Science. This system was not based on AI. It relied on traditional methods of collecting and analysing environmental data, such as pollutant levels and weather conditions.
3. Waste Management Challenges
In many Indian cities, House hold waste ends up in landfills, massive dumping grounds where trash accumulates for years. These landfills release harmful gases, produce unpleasant odours, and sometimes catch fire. They also contaminate groundwater.
How AI Helps to manage waste?
AI can improve waste management in several ways:
1. The Pune Municipal Corporation have developed an AI-powered mobile application. Citizens can take photos of garbage piles and upload them through the app. The AI system identifies the location and type of waste, then automatically generates a work order for the nearest cleaning squad.
2. In Indore, waste processing plants are using AI-based automated sorting machines which help to segregate the plastic, metal, and organic waste efficiently.
NOTE: Nowadays, mobile applications are available where users can scan the object and check whether an item is recyclable or not.
4. Wildlife Loss
Loss of wildlife is a growing problem, with many animal and plant species declining due to habitat loss, poaching, and human-wildlife conflict. Some previous studies show that an increasing number of cell phone towers in cities is reducing bird populations.
How AI Helps to conserve wildlife?
AI is becoming an invaluable tool for wildlife conservation:
Trail Guard AI cameras have been deployed in many tiger reserves in India. This system detects animals like tigers and other species, identifies them, and shares the information with officials in real time.
In India, the Forest Survey of India (FSI) collects the Indian forest satellite images annually and automatically detects deforestation, degradation and forest cover changes based on image processing with AI.
5. Soil Degradation:
Nowadays, soil degradation is a major environmental issue worldwide. The factors affecting soil degradation are mainly unsustainable farming practices, excessive use of chemical fertilizers, deforestation, and industrial pollution.
How AI Helps to reduce soil degradation?
AI can assist farmers in understanding and improving soil health:
1. In the 2026 Union Budget, the Indian government announced an AI-powered platform called Bharat Vistaar to help farmers with localized information including soil conditions, weather, pest detection, and expert advice in their own languages.
2. The Indian Ministry of Agriculture and Farmers launched the CROPIC, which stands for ‘Collection of Real Time Observations and Photo of Crops. It is a mobile app that farmers can use to share shots of their crops. This system checks the health of crops and allows real-time tracking.
How is Artificial Intelligence Used in Healthcare?
India’s healthcare system serves over 1.3 billion people. AI is helping in healthcare sector by assisting with early disease identification, medical image analysis and decision support. Some of the important applications in healthcare where AI is now used in real life are:
- Medical Image Analysis
- Predictive Healthcare
- Remote Patient Monitoring
Medical Image Analysis
Medical imaging technique like X-rays, CT scans MRIs and ultrasound are used to diagnosed various health issues. In India, there is a shortage of radiologists, especially in rural areas. Limited access to medical imaging facilities affects the detection of serious conditions such as tuberculosis (TB), cancers and heart diseases at early stage.
How AI Helps
AI can analyse medical images with remarkable accuracy, often spotting details that human eyes might miss. For example:
1. AI can detect early signs of tuberculosis in chest X-rays. India has adopted AI-driven tools to automatically analyse chest X-rays for TB screening. This tool is validated by the Indian Council of Medical Research (ICMR).
2. AI can also help identify tumours or cancers with the scan images. The Telangana government has initiated a pilot programme to integrate AI into public healthcare facilities for the early detection of cancers using high-resolution imaging and reliable diagnostic analysis
Predictive healthcare
Predictive Healthcare helps to identify the health problems before they actually occur. It uses data from our medical records, lab reports, lifestyle patterns and even family history. By analysing trends and patterns, healthcare providers can identify patients who are at higher risk, enabling timely interventions and preventive care.
How AI Helps
AI analyses the patient data such as medical history, lifestyle habits and family history to identify individuals at higher risk of diseases such as diabetes, heart disease or certain cancers. In India, under the Ayushman Bharat Digital Mission (ABDM), health records of millions of citizens are being digitized, allowing AI-driven predictive tools to analyse patient data and flag high-risk individuals for timely interventions and preventive care.
Virtual Health Assistants
In India, mainly in rural areas, not everyone has easy access to a doctor. People may travel for hours to reach the nearest clinic. Even in cities, getting a doctor’s appointment can take days. Virtual health assistants help to bridge this gap.
How AI Helps
Virtual Health Assistants use AI to provide personalized and timely health support, helping patients access care without visiting a clinic or hospital. For example:
1. AI can remind patients to take medicines on time and schedule follow-up visits.
2. The government of Madhya Pradesh launched an AI-powered SUMAN SAKHI chatbot to provide 24X7 health information for women, especially on maternal care, high-risk pregnancy conditions.
AI and Intelligent Automation
Everyday routine tasks around us are accomplished fast and effectively with little human effort. This is only achievable with the inclusion of AI in automation.
Nowadays, AI-powered washing machines can automatically determine the load, fabric type and dirt level. They adjust the quantity of water used, the amount of detergent used, and the time it takes to wash. This improves washing efficiency, saves water and energy.
In India, AI-driven automation is used across a variety of sectors, including transportation, agriculture, banking, healthcare, and home appliances. Some of the important applications of AI in automation are:
1. Smart Transportation

Smart transportation uses advanced technologies to improve traffic flow, reduce congestion, and enhance road safety. By analysing real-time data from sensors, cameras, and GPS systems, transportation systems can make better decisions and respond quickly to changing conditions.
How AI Helps in making transportation smart?
AI can analyse traffic patterns using data from cameras, sensors, and GPS devices. This information helps in several ways:
1. In cities like Delhi and Bengaluru, AI has already been introduced in traffic signal systems, where signal timing adjusts based on real-time traffic conditions.
2. AI-powered cameras are already installed in many cities that automatically detect traffic violations such as speeding and not wearing a helmet and issue fines accordingly
2. How AI is used in Agriculture:
AI in agriculture is enabling automation of many farming activities, reducing manual work and improving productivity. Tasks such as irrigation, sowing, spraying fertilizers, and harvesting can now be automated using
smart machines and data-driven systems.
How AI Helps to empowers farmers?
AI empowers farmers with information and insights:
In India, the India Meteorological Department (IMD) provides weather forecasts to farmers. Using these predictions, farmers can decide the best time for sowing, irrigation, and harvesting.
In India, under the Soil Health Card Scheme, the government tests soil samples and provides detailed reports on soil nutrients to farmers.
In India, platforms like National Agriculture Market (e-NAM) and apps such as Kisan Suvidha help farmers identify pest and disease issues by analysing crop images.
3. How is AI Used in Smart Homes?
AI is making homes smarter and more convenient to live in by automating everyday tasks and improving comfort, security. Devices such as smart lights, security cameras and voice assistants can learn user preferences and adjust settings automatically.
How AI Helps in making home smarter?
AI plays a significant role in making home smarter. For example:
AI can automatically control the electrical appliances such as fan, light, washing machine and air conditioning (AC) based on your voice.
AI-powered cameras and sensors can detect the unusual activities at your home and share real-time alerts to the owner or nearest police station.
AI in the Modern Education System
AI in modern education is transforming the way students learn and teachers teach. Tools such as automated assessment systems and virtual classrooms are making education more flexible and effective.
