- Researchers analyze data on climate change and the shared impact of plastics
- He found that the two were interchangeable, leading to a larger common issue.
- This prompted the team to say that the policies should consider both problems simultaneously
Politicians focused on tackling climate change are being urged not to forget that the world is in the midst of a global marine plastic pollution crisis.
Researchers from the Zoological Society London (ZSL) and Bangor University analyzed data on global climate change and marine plastic pollution, finding that they act to accelerate each other, creating a major overall problem for the planet. it occurs.
The effects of climate change on ocean ecosystems are widely studied, as are the effects of plastic pollution, but it remains to be seen how they act together.
Plastic manufacturing adds to greenhouse gas emissions, he said, and in turn leads to extreme weather events due to climate change. Spreading plastic pollution.
They say that so much energy is being spent on policies to reach zero and reduce carbon dioxide emissions, thereby ignoring the plastic problem.
Instead, experts say governments should consider both issues at the same time.

The interaction between plastics and climate. Plastics will affect climate change through the contribution of greenhouse gases and interact with the effects of climate change in the natural environment. Colored shapes indicate how each component is linked to both plastic pollution and climate change
- Plastic pollution and the climate change crisis compete for public and policy attention
- These issues are linked, some are vulnerable to both marine species and ecosystems.
- The root cause of both the crises is the same, overuse of limited resources.
- Persistence in solving plastic pollution can increase action against climate change
- Integrated approaches include preserving blue carbon and a circular economy
As part of the study, the team identified three important ways in which the climate crisis and plastic pollution are linked.
The first is how plastics contribute to global greenhouse gases throughout their life cycle, from production to disposal.
The second shows how extreme weather, such as floods and typhoons associated with climate change, will spread and worsen plastic pollution.
Finally, the third examines marine species and ecosystems that are particularly vulnerable to both climate change and plastic pollution.
Researchers warn that while climate change is a major issue, plastic pollution is having devastating effects on marine biodiversity.
From individual animals accidentally swallowing plastic bags to microplastic-polluted entire habitats, this is a problem that is getting worse.
Primarily derived from fossil fuels, and with increasing global demand, plastic production was responsible for emitting 56 billion megatons of CO2 from 2015 to 2020.
Although the figure has not been finalized based on estimates, the ZSL team says it accounts for between 10 and 13 percent of the entire global carbon budget.

Climate change is already causing more extreme weather events, including hurricanes and floods, to increase the spread of waste between land and ocean, the team said.
In addition, sea ice is a major trap for microplastics that will be released into the ocean as warming causes ice to melt, potentially entering global food chains.
Awareness and coverage of both issues has grown rapidly over the years, but studies show that they are often viewed as separate, even competing issues.
Professor Heather Koldavi, ZSL’s senior technical expert, a director of #OneLess, and senior author on the paper, says integrated solutions to mitigate both crises are possible and should be considered.
“Climate change is undoubtedly one of the most important global threats of our time,” explained Professor Koldavi.
Differences and biodegradability of different types of plastics. The effects of climate change on ocean ecosystems are widely studied, as are the effects of plastic pollution, but this is the first to look at how they act together.
They say that so much energy is being spent on policies to reach zero, and reduce carbon dioxide emissions, thereby ignoring the problem of plastics, and instead, allowing governments to do both at the same time. Issues should be addressed.
Paris Agreement: Agreement to limit the rise in temperature
The Paris Agreement, first signed in 2015, is an international agreement to control and limit climate change.
It is expected to advance efforts to keep the increase in global mean temperature below 2 °C (3.6 °F) and limit the increase to 1.5 °C (2.7 °F).
It seems that the more ambitious goal of limiting global warming to 1.5 °C (2.7 °F) may be more important than ever, and increasingly difficult.
According to previous research, if the temperature increased by 1.5C (2.7F), 25 percent of the world’s people could see a significant increase in drier conditions.
The Paris Agreement on Climate Change has four main goals with respect to reducing emissions:
Long-term goal of keeping the increase in global mean temperature below 2 °C above pre-industrial levels
The goal is to limit the increase to 1.5 °C, as this will significantly reduce the risk and…
