Every ten seconds the equivalent of a lorry full of plastic waste makes its way into the oceans, President Janos Ader said in an interview on Wednesday in connection with the upcoming sustainability expo dubbed Planet Budapest 2021. United Nations forecasts show that, combined with the effects of overfishing, this could result in plastic outweighing fish by 2050, he said. Ader told public radio that a third of the Earth's population receives their protein supplies from the oceans, and the volume of fish is therefore vitally important for feeding a growing population.
