The carbon footprint is a measure of the total carbon dioxide (CO₂) emissions caused directly or indirectly by an activity. Key features of Carbon Footprint 👉 In simple terms, it answers one question:“How much CO₂ am I responsible for emitting?” India’s Commitment on Carbon Footprint India has pledged to reduce the emissions intensity of its…
Introduction Certain gases present in the atmosphere have a special physical property—they can absorb and re-emit outgoing infrared radiation from the Earth’s surface. These gases include: Because they trap heat and prevent it from escaping back into space, they are called greenhouse gases (GHGs), and the warming they cause is known as the greenhouse effect….
When we talk about Climate Change (CC), we are referring to long-term shifts in Earth’s climate system—not just temperature, but also rainfall patterns, snowfall, wind systems, and ocean circulation. These changes occur over hundreds of years and can arise due to natural factors as well as human activities. Role of Human Activity (Anthropogenic Causes) While…
Introduction We have already studied about land degradation and conservation in Biogeography. Here we will mostly focus on land degradation and conservation from environment point of view. However, before starting let’s revise a bit what we had studied: Soil Degradation Causes of Soil Degradation Soil Erosion Soil Conservation Increasing Degraded Land in India Land is…
When we study environmental regulation in India, a major focus is on industries that have a disproportionately large impact on air and water quality. The government identifies these industries, categorises them, and then monitors them through specialised systems. Let’s understand this: Highly Polluting Industries (HPIs) The Ministry of Environment, Forest and Climate Change (MoEFCC) has…
Electronic waste (e-waste) is one of the fastest-growing waste streams in the world, and also one of the most dangerous, because it mixes:→ hazardous substances→ heavy metals→ toxic chemicals→ plastics & flame retardants……with valuable metals such as gold, silver, copper, platinum. What is E-Waste? E-waste includes discarded or end-of-life:→ electronics→ electrical equipment (EEE)→ appliances (TVs,…
Introduction Heavy metals are among the most dangerous environmental pollutants because they:➡️Persist in the environment➡️Do not biologically degrade➡️Accumulate in living organisms➡️Move up the food chain (biomagnification) Even at very low concentrations, they can cause severe and irreversible health effects. What Are Heavy Metals? Heavy metals are metallic elements with densities higher than water and with…
To understand hazardous waste, remember one principle: Not all waste is equally harmful, but hazardous waste is dangerous because of its chemical nature. What Is Hazardous Waste? A hazardous substance is any material present or released into the environment that can:→ Harm public health→ Damage ecosystems A substance becomes hazardous if it exhibits any ONE…
To understand solid waste, imagine everything we throw away—from kitchen leftovers to demolished concrete. If it is solid and discarded, it becomes solid waste. What Are Solid Wastes? Solid waste includes:→ Garbage→ Construction debris→ Sludge from treatment plants→ Other discarded materials They originate from:→ Industries→ Commercial establishments→ Mining activities→ Agriculture→ Households A major category is…
Let us begin with a very simple idea: Plastic itself is not the villain.The mismanagement of plastic is the real problem. And when this mismanaged plastic accumulates in the environment, we call it plastic pollution. What Is Plastic Pollution? Plastic pollution means the accumulation of plastic objects and particles—like bottles, bags, or microplastic fragments—in the…
