Why Plastic pollution is a problem?

Why is it important ? Plastic pollution is the most widespread problem affecting the marine environment. It also threatens ocean health, food safety and quality, human health, coastal tourism, and contributes to climate change.

How plastic is affecting the environment?

How does plastic harm the environment? Plastic sticks around in the environment for ages, threatening wildlife and spreading toxins. Plastic also contributes to global warming. Almost all plastics are made from chemicals that come from the production of planet-warming fuels (gas, oil and even coal).

Why do we need plastic?

Plastic packaging serves several important functions in our modern lives, which are the primary reasons we rely on it: Protection: protects vulnerable products from damage whilst in transit and from contamination or damage by moisture, humidity, gases, microorganisms, insects and light.

Why is plastic important?

Plastics clearly constitute an important component of the range of materials used in modern society. Almost all aspects of daily life involve plastics or rubber in some form or the other. Owing to their light weight, plastics reduce transportation costs and, therefore, atmospheric carbon dioxide emissions.

What are the five uses of plastic?

Plastic is used across almost every sector, including to produce packaging, in building and construction, in textiles, consumer products, transportation, electrical and electronics and industrial machinery.

What are the properties of plastic?

Plastics are generally low cost, easy to manufacture, durable, strong for their weight, electrically and thermally insulative, and resistant to shock, corrosion, chemicals, and water.

What are the 3 properties of plastic?

Why are there many types of plastic?

Although plastics can be broken down into broad types or categories, there actually are thousands of different plastics, each with its own composition and characteristics. One plastic may block oxygen from reaching food. Plastics are a result of a mix of chemistry and engineering.

What happen to plastic waste?

There are three main ways the plastic we use every day ends up in the oceans. Plastic you put in the bin ends up in landfill. When rubbish is being transported to landfill, plastic is often blown away because it’s so lightweight. From there, it can eventually clutter around drains and enter rivers and the sea this way.

What happens to plastic in water?

Unlike some other kinds of waste, plastic doesn’t decompose. That means plastic can stick around indefinitely, wreaking havoc on marine ecosystems. Some plastics float once they enter the ocean, though not all do. As the plastic is tossed around, much of it breaks into tiny pieces, called microplastics
