The combustion of fossil fuels from a range of sources, such as electricity, cars, airlines, space heating, manufacturing, or the ocean, is responsible for many of the human behaviours that lead to a hotter atmosphere. Overconsumption occurs when resource consumption exceeds the ecosystem’s sustainable capacity. The ecological and footprint, the resource is accounting approach that […]

This invisible ailment manifests itself when the concentration of pollutants on the surface reaches such a high level that it harms land biodiversity and endangers human health, particularly through food. Stock breeding and intensive farming use chemicals, pesticides, and fertilisers, which pollute the land, just as heavy metals and other natural and man-made chemical substances

Introduction Are you aware that haloalkanes and haloarenes can be found in the environment? During the Vietnam War, haloarenes were employed as herbicides to defoliate the jungles and make it simpler to battle. Microorganisms such as bacteria are unable to break down these haloarenes. As a result, it has remained unaltered in the rainforest soils

Haloarene is a halogenated aromatic hydrocarbon formed when a halogen atom replaces an aromatic hydrocarbon’s hydrogen atom. Haloarenes were employed as herbicides during the Vietnam War to defoliate jungles and simplify soldiers’ battles. Bacteria cannot eat and degrade these haloarenes. Consequently, it has continued to exist in its native state in rainforest soils until today.

These compounds have the chemical formula CxHy, which stands for CxHy.  Hydrocarbons can be found in both plants and trees, indicating their presence.  Carotenes, for example, are an organic pigment that can be found in green leafy vegetables and carrots. In natural crude rubber, these hydrocarbons account for up to 98 percent of the total. 

Almost all living things present on our earth contain carbon. As we read earlier even most parts of our body are made up of carbon, lots of it. For example, if we weigh 100 pounds, approximately 18 pounds of our body is made up of carbon. And we can declare plants as almost half carbon

Pollutants are the elements, molecules, and particles that contribute to pollution; when exposed to these materials, life can be harmed, and the effects on humans and plants are well known. Pollutants can enter the environment in a variety of ways, both naturally and by humans. What pollutants do once they are released into the atmosphere,

Dr. Henry Antoine Des Voeux first used the term smog in a paper in 1905 to describe the combination of smoke and fog that had been plaguing London at the time. Since then, London has enacted strict air pollution regulations, which have drastically reduced smog incidents in the region; however, London-type smog remains a major

It could be hazardous waste, including poisonous and non-hazardous trash. Industrial waste can contaminate groundwater, lakes, streams, rivers, and coastal waterways, as well as harm the soil and neighbouring water bodies.. Industrial pollution is contamination that can be traced back to a specific industry. One of the most widespread sources of pollution on the globe

With the advent of the Industrial Revolution, humans were able to make significant strides forward into the twenty-first century. Technology advanced at a rapid pace, science advanced to a high level, and the manufacturing age came into view. Aside from all of this, there was another consequence: Industrial pollution–Previously, industries were small factories that were
