Nature

Organic wastes, improperly disposed, cause problems of oxygen depletion, pollution and foul smells.

Background

The breakdown and decay of living material requires oxygen. The amount of oxygen consumed by a given amount and type of organic material when broken down in nature is know as its biological oxygen demand (BOD). Chemical oxygen demand (COD) is the even greater amount of oxygen that would be needed to completely oxidize the material in a laboratory. Both indices are used as measures of the organic content of waters.

Incidence

Organic wastes constitute a significant global challenge, with billions of tonnes generated annually from households, agriculture, food processing, and municipal sources. Inadequate management leads to environmental pollution, greenhouse gas emissions, and public health risks, particularly in rapidly urbanizing regions and developing countries lacking effective waste infrastructure. The scale of the problem is exacerbated by increasing population density and changing consumption patterns, making organic waste a persistent and escalating issue worldwide.
In 2022, the city of Bengaluru, India, faced a severe crisis when over 3,000 tonnes of uncollected organic waste accumulated daily, overwhelming local landfills and causing widespread air and water contamination.

Claim

Organic wastes are being widely used as a fuel in many parts of the world instead of being returned to the soil.

Counter-claim

Frankly, the concern over organic wastes is vastly overblown. These materials are natural, biodegradable, and return nutrients to the earth. Unlike plastics or toxic chemicals, organic waste poses minimal long-term harm. Nature has managed organic matter for millennia without human intervention. Focusing on organic waste distracts from truly pressing environmental issues. It’s simply not an important problem and does not deserve the attention or resources currently being devoted to it.
