The past century has seen a 0.8 °C increase in average global temperature, and according to the IPCC, the overwhelming
source of this increase has been emissions of greenhouse gases and other
pollutants from human activities.
Recalling the concern reflected in the outcome document of the United Nations Conference on Sustainable Development, entitled «The future we want», 1 that the health of oceans and marine biodiversity are negatively affected by marine pollution, including marine debris, especially plastic, persistent organic
pollutants, heavy metals and nitrogen - based compounds,
from numerous marine and land - based
sources, and the commitment to take action to significantly reduce the incidence and impacts of such pollution on marine ecosystems, Noting the international action being taken to promote the sound management of chemicals throughout their life cycle and waste in ways that lead to the prevention and minimization of significant adverse effects on
human health and the environment, Recalling the Manila Declaration on Furthering the Implementation of the Global Programme of Action for the Protection of the Marine Environment
from Land - based Activities adopted by the Third Intergovernmental Review Meeting on the Implementation of the Global Programme of Action for the Protection of the Marine Environment
from Land - based Activities, which highlighted the relevance of the Honolulu Strategy and the Honolulu Commitment and recommended the establishment of a global partnership on marine litter, Taking note of the decisions adopted by the eleventh Conference of the Parties to the Convention on Biological Diversity on addressing the impacts of marine debris on marine and coastal biodiversity, Recalling that the General Assembly declared 2014 the International Year of Small Island Developing States and that such States have identified waste management among their priorities for action, Noting with concern the serious impact which marine litter, including plastics stemming
from land and sea - based
sources, can have on the marine environment, marine ecosystem services, marine natural resources, fisheries, tourism and the economy, as well as the potential risks to
human health; 1.
