It is caused by the mismanagement of solid waste from human & their activities, waste collectors and waste disposal contractors. The effects of this type of pollution is the spread of harmful bacteria in the surroundings, as well as obnoxious odors which will also end up as air pollution. The water will also get contaminated, which will transmit parasites and bacteria to humans.
In most of the world, including North America, we do one of two things with our ordinary garbage: burn it or bury it. Neither one is good for us or for the environment. Burning garbage in incinerators releases dangerous gases and dust (particulate matter) which contribute to global warming and pollute lakes, forests, oceans and cities half a world away from where they originated. Most incinerators in industrialized countries now remove large quantities of particles and pollutants, thus ensuring cleaner air. But the bulk of what they remove ends up in a landfill.
Mismanaged waste causes hundreds of thousands of people to die each year in the developing world from easily preventable causes, and plastic waste is adding a new and dangerous dimension to the problem, a report has found.
Municipal waste frequently goes uncollected in poorer countries and its buildup fuels the spread of disease. Between 400,000 and 1 million people are dying as a result of such mismanaged waste, according to the charity Tearfund.
While mismanaged waste has been a problem for decades, the growth of plastic pollution, , which does not break down in the environment, is adding a fresh set of problems to an already dire situation. When some plastics deteriorate, they can leach harmful chemicals into the environment and break down into microplastics. While most attention has focused on the effects of marine plastic pollution in the natural world, its effects on people are equally problematic. About 8m tonnes of plastic waste are dumped into the seas each year, according to the UN, and there are few ways of retrieving it. Among the other harmful impacts of plastic pollution are the loss of fishing, damage to agriculture, up to a third of cattle and half of goats in developing countries have consumed significant amounts of plastic.
Nearly 30 per cent of the food produced worldwide is lost or wasted every year. This waste contributes to biodiversity loss through habitat change, over exploitation, pollution and climate change. Food is the primary source of landfill gas and the largest component of materials sent to landfills, which leads to methane emissions that cause climate change.
The world produces as much as 50 million tonnes of electronic and electrical waste (e-waste) a year, weighing more than all of the commercial airliners ever made. Only 20% of this is formally recycled. The e-waste produced annually is worth over $62.5 billion, more than the GDP of most countries.
Waste pollution is one of the broadest social and environmental issues. There’s many different types of waste, different ways that waste can pollute the environment, and a range of effects that waste pollution can have across society.
We are producing gigantic amounts of waste. Total waste in the world is enormous. Some of it is recycled but a lot is simply dumped, causing problems for people and the environment. Every year we dump a massive 2.12 billion tons of waste. If all this waste was put on trucks, they would go around the world 24 times. This stunning amount of waste is partly because 99 percent of the stuff we buy is trashed within 6 months. Zero waste is a philosophy that encourages redesign so that all products are reused.
