Definition of Pollution: Pollution refers to the introduction of contaminants or harmful substances into the environment, which alters its natural state and poses risks to human health, wildlife, and ecosystems. Impact on Mediums: Pollution can affect different mediums, namely air, water, and soil. When pollutants are released into these mediums, they undergo changes that can make them hazardous or unsuitable for their intended purposes. Types of Pollutants: 1. Chemical Pollutants: These are substances released into the environment as a result of industrial processes, agricultural activities, or human-made products. Examples include industrial chemicals, pesticides, fertilizers, and household cleaners. 2. Dust: Dust pollution occurs when fine particles are suspended in the air, often originating from sources such as construction sites, unpaved roads, agricultural activities, and industrial processes. 3. Noise: Noise pollution refers to excessive or disruptive sounds that can have adverse effects on human health and wildlife. Common sources of noise pollution include transportation (e.g., vehicles, aircraft), industrial activities, construction sites, and loud machinery. 4. Radiation: Radiation pollution involves the release of ionizing or non-ionizing radiation into the environment, which can have harmful effects on living organisms. Sources of radiation pollution include nuclear power plants, medical facilities, and certain industrial processes. Harmful Effects: Pollution can have detrimental effects on human health, including respiratory problems, cardiovascular diseases, neurological disorders, and cancer. It can also harm wildlife and ecosystems, leading to habitat destruction, biodiversity loss, and ecological imbalances. In summary, pollution alters the natural composition of air, water, or soil through the introduction of various pollutants, including chemicals, dust, noise, and radiation. Understanding the sources and impacts of pollution is crucial for implementing effective mitigation strategies to safeguard human health and the environment. #pollution #airpollution #noisepollution #chemicalpollution

Here is an important explanation about the many types of pollution that can affect people and nature.

DYK that the ocean absorbs over 1/4 of CO₂ emissions from human activities? This leads to a process called #OceanAcidification, making it harder for marine organisms to build their shells and skeletons. Let's take action to protect our ocean! #ClimateChange.

New study on Tropical Peat Fires & Carbon Emissions。🌴 Human activity degrades peatlands, releasing significant aerosols & climate-affecting gases. This finding provide crucial data for enhancing GHG estimates. 🌎 https://lnkd.in/dSrQMDts #PeatFires #ClimateScience

An Arctic-wide survey has found that the permafrost region is emitting more carbon into the atmosphere than it absorbs, causing the planet to heat even further… Areas of permanently frozen ground in northern regions are now emitting more carbon into the atmosphere than they absorb, causing the planet to heat even further, according to the first Arctic-wide estimate of all three major greenhouse gases.

Have you registered for our latest online course on Introduction to Air Pollution Modelling, to be presented by Dr Paolo Zannetti from The EnviroComp Institute, USA, from 12-14 November 2024? All aspects of air pollution will be discussed: emissions, atmospheric processes, chemical concentration and deposition impacts, and adverse effects on humans and the environment. The available software tools for simulating air quality matters will be presented, including the simulation of meteorological parameters needed for air quality analyses.

Really clever attention grabbing video & interactive important message. As a #marinescience major (that switched to #sportsmarketing) always interested in the heath of our #oceans and their #biodiversity. If you think it’s fun seeing the orca jump across the page - even more incredible to see in person. Sadly, their environment is being negatively impacted by humans as well. All the global ecosystems are connected more than you realize - taking care of your backyard helps everyone’s. See you protecting the marine environment!!! #marineenvironment #sustainability IPBES #saveouroceans #marinelife #marineecosystems #orcas

Human activities affect marine ecosystems in multiple ways. And it’s not always just because we fish! Does your business have a good understanding of its impacts and dependencies on the marine life? IPBES provide more insight in the scale of impacts You can also check out our blog to help you take the first steps towards connecting the dots. Link in the comments

Oceans governance and protection has direct impact on all of us! Reducing human pressure is of utmost importance to protect habitat and species,and the ecosystem as a whole.

#TheRippleEffect Human Impact on Our Oceans 🌊 Human activities have significantly impacted our oceans through: ⚠️ Direct Exploitation: Overfishing and resource extraction ⚠️ Pollution: Contaminants from both land and sea-based sources ⚠️ Land/Sea-Use Change: Coastal development and habitat destruction Our oceans are vital to our planet's health and must be protected. #OceanConservation #Sustainability #ClimateAction #ProtectOurPlanet
