As the global population increases rapidly, societies around the world need to come up with more efficient solutions to controlling waste. Excess litter and refuse pose a serious threat to the environment. Illegal dumping and littering are two of the major contributors to pollution in our rivers, oceans, public spaces and countryside. Keeping our environment clean is a collective responsibility that we all share.
Every citizen has a role to play in protecting the environment from pollution. We need to eradicate litter and avoid irresponsible waste disposal practices immediately. There is no excuse for plastic waste in the environment – it should always be recycled and thrown away in a responsible manner. Make a point of finding out more about what can and can’t be recycled, and start separating at home. Plastic is a valuable resource that is too important to simply dump and never use again.
We need to reduce, reuse and recycle our waste wherever possible. This will keep litter out of the environment.

Every South African needs to take responsibility for their waste and disposal habits.
