Plastic and humans are inseparable. More than 500 billion plastic bags are used by people all around the world every year. That translates to one million bags used every minute. The figure more than shows human’s dependence on the useful but dangerous materials.

According to statistics, Malaysians threw recyclable materials valued at RM476 million two years ago, and plastic was the second biggest item thrown, after paper.

Not many people realize that excessive use of plastic, especially plastic bags, with improper disposal management, can have destructive effects on many life forms including humans.

“One million seagulls and more than 100,000 sea mammals have died due to human-created plastic waste drifting in the oceans,” said Dr Yusof Shuaib Ibrahim, a researcher at Universiti Malaysia Terengganu (UMT) currently attached to the Facult of Science and Marine Environment.

Many turtles have died from eating plastic bags, which closely resemble jelly fish when seen in the oceans.  

Improper disposal of plastic bags also contributes towards the formation of green house effects, which in turn increases global warming.

Even more worrying is that careless plastic dumping creates another dangerous threat—microplastics. Microplastics are small plastic particles and synthetic fibre that exist after plastic has broken apart.

“Plastic humans dump will drift into the oceans and will not disintegrate or disappear just like that. In fact, eventually it will become microplastics that will be eaten by marine lives,” said Dr Yusof, a biologist who studies microplastic and is a member of UMT Microplastic Reasearch Interest Group.

“When marine organisms eat microplastics, the materials will be trapped inside their body especially in the stomach,” he said.

Making microplastics more dangerous is the fact that they are not very visible to the naked eyes.

According to Dr Yusof, humans swallow around 5 grams of microplastics in a week. “The 5 grams is almost equivalent to a credit card, so humans in essence eat a credit card a week.”

Microplastics not only endanger marine lives and human’s health, they also pose a threat to plants.

Plastic waste and microplastics will remain dangerous threats to every life forms on earth unless humans start to discard plastic properly.

When humans do that, plastic and humans can remain inseparable, without any destructive effects damaging the relationship.
