In “More-than-Human Politics: The Case of Plastic Bags” Gay Hawkins argues that culture is anthropocentric in the way that humans interact with objects and matter. Hawkins argues that people should become more aware of the subject-object relationship. Hawkins is attempting to equalize the relationship between object and human‚ and escape from the cultural view always focused on humans. As Hawkins says‚ “My broad aim is to show why socio-ecological humanities research needs to pay more attention to

They drift in the wind over America’s great prairies and are caught on rocks at the highest peaks. Animals are seen wrapped in plastic struggling to move and breathe while others lie motionless on the ground having given up the struggle to free themselves. Society’s descendents can no longer lie on the beach and enjoy the sun due to the thick layer of plastic covering

Many solutions exist to reduce the negative externalities of plastic bags. The three main solutions available are taxations on plastic bags‚ bans on plastic bags and subsidies to improve methane capture technologies. The following provides a discussion on each of the solutions‚ including the advantages and disadvantages of each solution: Solution 1: Taxation on plastic bags Imposition of a tax equal to the cost of the negative externality can internalise the externality amongst consumers and

BIODEGRADABLE SM PLASTIC BAG IN DIFFERENT SUBSTRATE ABSTRACT The purpose of this Investigatory project is to determine the effect of different substrates on the biodegradability of SM plastic bags. The materials needed are: 6‚ 1-litre glass jars; 6‚ 7”x9” aluminums trays; 12 pcs. 3”x4” SM plastic bags; 500g loam soil; 500g compost soil; 500mL seawater; 500mL tap water; Analytical balance; Graduated cylinder; and Weighing scale. The procedure involved cutting the SM plastics bags into 3”x4” sizes

Many technologies exist today that allow for such treatment. Currently there are some synthetic polymers that can be broken down by microorganisms

IMPORTANCE OF PLASTIC:- Plastics are a subset of materials known as Polymers. These are composed of large molecules formed by joining many smaller molecules together (monomers). Other kinds of polymers are fibres‚ elastomers‚ surface coating and biopolymers‚ such as cellulose‚ proteins and nucleic acids. Plastics owe their name to their ability to be shaped to form articles of practical value by various conversion and forming processes. These are some peculiar properties of plastics materials‚ which

OCEAN PLASTICS POLLUTION: A GLOBAL TRAGEDY FOR OUR OCEANS AND SEA LIFE Plastic never goes away. And it’s increasingly finding its way into our oceans and onto our beaches. In the Los Angeles area alone‚ 10 metric tons of plastic fragments — like grocery bags‚ straws and soda bottles — are carried into the Pacific Ocean every day. Today billions of pounds of plastic can be found in swirling convergences making up about 40 percent of the world’s ocean surfaces. Plastics pollution has a direct and
