Key Highlights from the News
The article strongly criticizes the plan to use cloud seeding to reduce the severe air pollution in Delhi.
The author argues that it is merely a "science misapplied," "ethical failure," and "gimmick," and an attempt to distract from the real issues.
Cloud seeding requires natural clouds; it cannot create them. However, Delhi's winter air is too dry and stable for rain clouds to form.
Even if rain reduces pollution, it will only be a temporary respite. Pollution will return to previous levels within one or two days.
The long-term effects of this process, which uses chemicals like silver iodide, are unclear.
The article also raises a serious question about accountability if this project causes floods or crop damage.
The article calls for structural solutions that control the sources of pollution, such as vehicles, industries, and stubble burning.
