Scientists are warning that reflecting the sun's rays, a concept being explored as a potential solution to global warming, could have unintended consequences, including crop failure. However, the specifics and feasibility of such a plan, often referred to as solar geoengineering, are still being debated among experts, with some raising practical and ethical concerns. The effectiveness and safety of this approach to mitigating climate change remain uncertain, with differing opinions on whether it should be pursued or banned.
