2. Plastic is any of a wide range of synthetic or semi-synthetic
organic solids of high molecular mass that are moldable.
most commonly derived from petrochemicals.
It is now difficult to conceive a world without plastics. It is
hard to trace out any area where plastics is not used

3. Types of Plastics
THERMOPLASTICS

hygiene
Reduces land fertility
Adversely affects plant growth by
inhibiting nutrient absorption.

Bioaccumulation of microplastics
Contaminated drinking water sources
cause diseases
Degradation of ecosystem

8. Incineration of plastic waste in an open field release
toxic gases like dioxins, furans & PCBs.
Even during production, PVC plants can
release dioxins
Some gases emitted contribute to global warming.
Polluted air causes respiratory diseases in living
organisms
Plastics contain additives that can offgas and
contaminate the air in our homes

food.
Small plastic fragments called microbeads,
which resemble fish eggs, are routinely
found in the stomachs of numerous sea
creatures

Marine animals get entangled in plastic
waste and die
