Prevention of plastic pollution
Most of today’s plastics are made from Organic polymers produced from petroleum- based Chemicals.
With the production outspacing almost every other material production, plastic waste is now one of the biggest environmental scourges of the time.
According to the state of plastics report, only nine percent (9%) of the nine billion tonnes of plastic in the world ever produced has been recycled.
Most ends up in landfills, dumps or in the environment especially the oceans.
The estimate show that over 400,000 marine mammals perish every year due to plastic pollution in oceans.
The scale of the challenge is daunting. The exposure of humans to plastic pollution also has health challenges.
Plastics consist of major toxic pollutants having the potential to cause important harm to the environment in the form of water, land and air pollution
Groundwater Pollution
It Upsets the Food Chain
Killings of Animals
Land pollution
Poisonous Ability
Air Pollution
The plastic pollution is poisonous. Plastic pollution has the potential to poison animals, which can then adversely affect human food supplies.
It is the presence of chemicals in the atmosphere in concentrations high enough to harm organisms, ecosystem, or human made materials, or to alter climate
Plain old trash
Fishing nets
Disposing of plastic
Plastics are found everywhere along the streets and roads of every cities and towns making them to be untidy.
Trash dumps and landfills are major problems because the pollutants are allowed to get into the ground thereby affecting the wildlife and groundwater.
The plastic pollution on the land poses a threat to the plants and animals including humans occupying the land.
The amount of plastic poised on the land is greater and more concentrated than that in the water.
The cartons of some products such as can-milk, can- beverages, can-tomatoes are lined with plastics so as to allow proper packaging.
Plastic drinking bottles, water bottles, straws and stirrers used for soft drinks
The ocean has faced different problems of plastics pollution created by the fishing industry.
The nets used for large scale fishing activities are usually made of plastic
The largest ocean-based source of plastic pollution is discarded fishing gear which includes traps and nets, and it is estimated to be up to 90% of plastic debris in some areas.
The ropes and nets used for fishing activities are often made of synthetic materials such as nylon
These fishing nets become submerged in water, on spending much time it releases toxin at will. Later, they get broken up.
This kills and harms the local wildlife, but it ensures that pollutants enter the water and fish of the area
Plastics have complex chemical composition. This makes plastic to be durable and do not break down easily.
Plastics and resins have different properties related to contaminant absorption and adsorption depending on their chemical composition
Most of the wastes in the form of plastic in landfills, are single-use items such as packaging.
The recycling of plastics is not enough to reduce the large number of plastics that litters everywhere.
The polymer degradation takes a long period of time due to saline environments and cooling effect of the sea.
The process of recycling plastic could result to the release of plastic irritants and harmful chemicals into the environment.
This may change as scientists shift to developing plastics made from biologically based chemicals.
Reuse
Reduce
Recycle
Reusability refers to the use of materials more than once in their original form instead of throwing away after each use
In order to reduce plastic pollution, there is need to reduce our usage of plastic.
Recycling of plastic involves collection of plastic waste and reprocessing it into new products, in order to reduce the amount of plastic in the waste stream.
