How does food waste affect the environment and human health?

But wasted food isn’t just a social or humanitarian concern—it’s an environmental one. When we waste food, we also waste all the energy and water it takes to grow, harvest, transport, and package it. And if food goes to the landfill and rots, it produces methane—a greenhouse gas even more potent than carbon dioxide.

How does waste affect humans and the environment?

Poor waste management contributes to climate change and air pollution, and directly affects many ecosystems and species. Landfills, considered the last resort in the waste hierarchy, release methane, a very powerful greenhouse gas linked to climate change.

How does plastic waste affect humans?

Plastic products contain chemical additives. A number of these chemicals have been associated with serious health problems such as hormone-related cancers, infertility and neurodevelopment disorders like ADHD and autism.

How is waste harmful to the environment?

Some waste will eventually rot, but not all, and in the process it may smell, or generate methane gas, which is explosive and contributes to the greenhouse effect. Leachate produced as waste decomposes may cause pollution. Badly-managed landfill sites may attract vermin or cause litter.

How does waste affect people’s health?

The more emissions that we produce due to how much trash we generate, affects us long term. One can develop diseases such as asthma, birth defects, cancer, cardiovascular disease, childhood cancer, COPD, infectious diseases, low birth weight, and preterm delivery.

What happens to waste from food in the body?

Your large intestine is the final part of your digestive tract. Undigested food enters your large intestine from your small intestine.

What happens if waste is not removed from the body?

Your body also needs to remove the wastes that build up from cell activity and from digestion. If these wastes are not removed, your cells can stop working, and you can get very sick. The organs of your excretory system help to release wastes from the body.

Why is wasting food a problem?

Food waste is a problem because it costs Americans billions of dollars in lost revenue, puts a tax on natural and human resources, and harms the environment by contributing to global warming and climate change when food waste is added to landfills and produces the greenhouse gas methane.

What is the social impact of food waste?

Food waste is not only a social cost, but it contributes to growing environmental problems like climate change, experts say, with the production of food consuming vast quantities of water, fertilizer and land. The fuel that is burned to process, refrigerate and transport it also adds to the environmental cost.
