Globally, June 5 is observed as World Environment Day, to raise awareness and address the challenge of preserving the environment. 

This year, the United Nations has chosen to focus on solutions to beat plastic pollution that harms ecosystems, well-being and climate. The harm caused by plastic pollution has infiltrated every corner of Earth, from the top of Mount Everest to the depths of the ocean; from human brains; to human breastmilk, mentioned the UN Secretary-General’s message.

According to a report in The Sentinel, microscopic plastic particles found in food and beverages can cause harm to organs such as the liver. Another study by the University of New Mexico has found the presence and accumulation of microscopic plastic particles in human brains. 

Various studies and research have emphasised the need for governments and organisations to take swift action to reduce plastic pollution.

Effect of microplastics on human health:

According to the National Institute of Health,  microplastics can affect various systems in the human body, including the digestive, respiratory, endocrine, reproductive, and immune systems.

When microplastics are ingested, it causes physical irritation to the gastrointestinal tract which may eventually cause inflammation, resulting in various gastrointestinal symptoms. They can also act as carriers of other environmental toxins. 

According to the UN Environment Programme, only 21 per cent of plastic today is economically recyclable, which means that the value of the recycled material is high enough to cover the cost of collecting, sorting, and processing it. 

It is estimated that in 2025, the world is expected to consume 516 million tonnes of plastics and by 20260, the annual global plastic consumption is forecast to reach over 1.2 billion tonnes.
