Question

write a short note on plastic and health care industries

Answer 1

Beat Plastic Pollution”, the theme for World Environment Day 2018, is a call to action for all of us to come together to combat one of the great environmental challenges of our time. Chosen by this year’s host, India, the theme of World Environment Day 2018 invites us all to consider how we can make changes in our everyday lives to reduce the heavy burden of plastic pollution on our natural places, our wildlife – and our own health.

While plastic has many valuable uses, we have become over reliant on single-use or disposable plastic – with severe environmental consequences. Around the world, 1 million plastic drinking bottles are purchased every minute. Every year we use up to 5 trillion disposable plastic bags. In total, 50 per cent of the plastic we use is single use.

Nearly one third of the plastic packaging we use escapes collection systems, which means that it ends up clogging our city streets and polluting our natural environment. Every year, up to 13 million tons of plastic leak into our oceans, where it smothers coral reefs and threatens vulnerable marine wildlife. The plastic that ends up in the oceans can circle the Earth four times in a single year, and it can persist for up to 1,000 years before it fully disintegrates.

Plastic also makes its way into our water supply – and thus into our bodies. What harm does that cause? Scientists still aren’t sure, but plastics contain a number of chemicals, many of which are toxic or disrupt hormones. Plastics can also serve as a magnet for other pollutants, including dioxins, metals and pesticides.

The plastics industry manufactures polymermaterials — commonly called plastics — and offers services in plastics important to a range of industries, including packaging, building and construction, electronics, aerospace, and transportation.

It is part of the chemical industry. In addition, as mineral oil is the major constituent of plastics, it is regarded a part of thepetrochemical industry.

Besides plastics production, plastics engineering is an important part of the industrial sector. The latter field is dominated by engineering plastic as raw materialbecause of its better mechanical and thermal properties than the more widely used commodity plastics.
