Scientists indicate the dangers of microplastics for crops

• Microplastics reduce photosynthesis by up to 12%, threatening yields.
• Countries did not manage to agree on limiting plastic production at the recent UN negotiations.
• The reduction of plastic production is critically important for ecology.

Microplastics, which penetrate into crops, can significantly disrupt the process of photosynthesis, which is critically important for life on Earth. These particles, which come from the breakdown of larger plastic items, are found even in remote corners of the planet, including human organs.

Research indicates that microplastics can reduce photosynthesis by 12%, which may lead to reduced yields of agricultural crops and marine phytoplankton. Scientists warn that this could leave millions of people without reliable access to food.

Microplastics enter crops through groundwater, when they mix with water and living organisms. They can disrupt the flow of water and the distribution of living organisms, which affects plant growth. Studies have shown that microplastics can also reduce the ability of plants to absorb carbon dioxide, which impacts climate change.

Against the backdrop of increasing problems with plastic pollution, countries did not manage to reach an agreement at the latest UN negotiations regarding limiting plastic production. Most countries have made significant reductions in production, while others, including the USA and a number of oil-producing states, oppose such restrictions.

Scientists emphasize the importance of reducing plastic production, as 99% of plastic products are made from virgin fossil fuels. Currently, nearly 400 million tons of plastic are produced annually, and without changes in policy, this figure could increase by 70% by 2040.
