This makes science not really credible. I see nevertheless that approaches such as the ones of Zhu et al are important - as micro- and nanoplastics are likely a global threat. But we - the scientists- need to put our results into a realistic context - this is our core responsibility.

This paper is a perfect example how trying to get newspapers-citable into the focus of a paper invalidates the really important findings (microplastics can reduce photosynthesis but we do not know how this might scale to our ecosystems - just because we have no data at all.

Just imagine you go with machine learning from scarce lab data with almost no information on plastic pollution under real world conditions to crop and fishery yield losses as a result of that given pollution. I acknowledge that this is a first step - but you need to name the shortcomings.

They (1) extrapolate plastic impact measurements on photosynthesis under controlled and highly artificial conditions to the real world (2) without valid data on global plastic pollution and (3) without any baseline for their model.

We still feel that this later statement in their response letter is not congruent with the alarming statements in the original text: „These findings underscore the urgency of integrating plastic mitigation into global hunger and sustainability initiatives“ which seem to be targeted to press coverage

In their response (www.pnas.org/doi/10.1073/...) some authors of the original paper state that „[they] believe it is scientifically sound and responsible to use currently available—albeit limited evidence—for preliminary assessments and to stimulate broader scientific and policy dialog“

This is our critical assessment of www.pnas.org/doi/10.1073/... These authors claimed that they can calculate quite exact MP-induced real world global photosynthesis losses translating in a reduction of 22.15 to 115.73 MT·y−1 in main crop production and 0.32 to 7.39 MT·y−1 in seafood production.

Integrating forest inventories with remote sensing and modelling is needed to better understand tree mortality. A global effort should promote equitable collaborations, empowering scientists from less wealthy regions. @treemortality.bsky.social nph.onlinelibrary.wiley.com/doi/10.1111/...

Summary of the spatial and temporal coverage of forest plots according to our survey of global mortality monitoring plots: (a) percent of the total forest area surveyed per country, (b) plot area surveyed over time for different continents and globally (black line), and (c) the distribution of size and number of plots. For countries coloured dark grey in (a), we did not receive any responses in our survey. Countries coloured light grey are countries with < 10% of their terrestrial land area covered by forests.
