Not failure, but low aim, is crime.

Particulate matter? Here's what it is and how to avoid it
Fine particulate matter (PM2.5) also harms agriculture. Lower pollutant concentrations in the air do not automatically translate to a reduced mortality risk.
This is the conclusion of an international study led by the Helmholtz Center Munich. Data from 380 cities worldwide was analyzed, revealing that air pollution endangers not only millions of people but also agriculture.
The World Meteorological Organization (WMO) emphasizes this in a recent report.
For the city study, published in The Lancet Planetary Health, levels of fine particulate matter and nitrogen dioxide were examined.
Both the microscopic particles and the gas—emitted by vehicles and industrial facilities—increase the risk of disease. Although the concentration of these pollutants in the studied cities decreased between 1995 and 2016, the associated risk of deadly cardiovascular and respiratory diseases did not significantly drop. This discrepancy could have multiple causes.
First, populations in many regions are aging, and older individuals are more vulnerable to health issues.
Second, changes in the origin and composition of pollutants might play a role. According to the WMO, air pollution causes over 4.5 million premature deaths annually and incurs enormous economic and ecological costs.
It comprises various components: "The chemicals that degrade air quality are often emitted alongside greenhouse gases," the WMO states.
Pollutants like nitrogen compounds, sulfur compounds, and ozone can settle on the Earth's surface, harming ecosystems. Reports from China and India suggest fine particulate matter could reduce crop yields in heavily polluted areas by as much as 15%. Deposits on plants block sunlight, impairing photosynthesis.
Ironically, agriculture itself contributes to air pollution. Burning fields, using fertilizers, and storing manure produce fine particulate matter. Yet massive clean-up efforts to address these issues are conspicuously absent. Politicians and industries are delaying action, ignoring the urgency of the crisis.
How do we move forward? Action must be uncompromising and immediate. March. Boycott. Strike. Use your voice, your wallet, or both.
Elect leaders who refuse to push empty promises like "net-zero by 2050." Write to your legislators and demand the adoption of cleaner technologies now.
Visit platforms like ClimateTrace.org to identify polluters in your area. Move away from airports, industrial zones, and highways if possible.
Stay grounded—fly less, use public transportation, consume less, and waste less.
Make no mistake: at this rate, we will soon need to grow our food under climate-controlled domes with filtered water. Where are the so-called “good billionaires” when humanity needs them most?
The time for half-measures and platitudes has passed. Without radical, immediate action, humanity's future will be suffocated—both literally and metaphorically—by its own apathy.
