Adopting plastic tax the way to go
However, one should hasten to emphasize that the South African economy is the largest in the SADC region has export markets in all the countries in the region. This means that it was able to combine a host of measures in this regard, such a charging tax on locally-consumed plastic bags as well as creating recycling companies which have thus far largely benefited from collection of plastic refuse even from neighbouring countries such as Lesotho.
It is without a doubt that any policy has externalities; that is negative or positive effects/impacts.
Therefore this means that while it may have a desired effect and bring about a solution to the problem at hand, it can affect both the retailers and consumers in a certain way. For instance, in the above mentioned cases, the negative externality was that lower income consumers were found to be hit hard by the introduction of taxes which is also a likely scenario
in Lesotho as the structure of the economies of the three countries, that is Botswana, Lesotho and South Africa are arguably the same given the same economic history they have. However, the imperative to protect the environment and to bolster tax revenue puts a country at the crossroads; therefore it will be highly beneficial to adopt a tax on plastic bag.
