Voice of climate-by Naseem Sheikh

In easy words, “the total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2).” This accounting approach compares how much people demand compared to what the planet can renew. The main influences on carbon footprints include population, economic output, and energy and carbon intensity of the economy. In most cases, the total carbon footprint cannot be exactly calculated because of inadequate knowledge of and data about the complex interactions between contributing processes, including the influence of natural processes that store or release carbon dioxide. For this reason, Wright, Kemp, and Williams, have suggested to define the carbon footprint as: “A measure of the total amount of carbon dioxide (CO2) and methane (CH4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the populatio...

Air pollution is a mixture of solid particles and gases in the air released both by natural and anthropogenic sources. Natural sources includes volcano eruption, soil erosion, wildfire, pollen and mold spores and volatile organic particles evaporation of mountain and sea salts due to high temperature. Anthropogenic sources includes traffic vehicle emissions, chemicals from factories, fumes of volatile organic compounds from hair spray, varnish, air freshener, body spray and other solvents, chemicals from fertilizers,controlled burn particles from agriculture and forests, hazardous waste gases from incineration and military weapon utilization. It may cause diseases, allergies and even death to humans; it may also cause harm to other wildlife and food crops, and may damage the natural or built environment.Some air pollutants are poisonous. Inhaling them can increase the chance of ill health problems. People with heart or lung disease, aged adults and children are at higher risk from a...
