GM Crops and Sustainable Farming
The world’s population is increasing, requiring more food, but expanding agricultural land and harmful practices like deforestation and pesticide use are not sustainable.
Genetically modified (GM) crops, like Bt cotton and Bt brinjal, help increase yields and resist pests, reducing the need for harmful pesticides and herbicides.
Herbicide-tolerant (HT) crops allow farmers to control weeds without harming crops, reducing labor and soil erosion.
These crops help achieve higher food production without expanding agricultural land or damaging ecosystems.
Health and Environmental Impact
Studies show negligible health risks from consuming GM crops; the main concern is the farming methods and associated management practices.
Insect-resistant GM crops have reduced pesticide use, benefiting both farmers’ health and the environment.
However, pests can develop resistance to GM traits, leading to increased pesticide use, which can be mitigated by diversifying crop types.
Herbicide Use and Resistance
Over-reliance on herbicides like glyphosate has led to weed resistance, causing farmers to use more chemicals, which can harm human health and the environment.
Some GM crops are modified to resist multiple herbicides (e.g., dicamba), but these can have toxic effects on both humans and non-GM crops nearby.
Resistance issues mirror antibiotic resistance in medicine, where constant use of the same herbicides leads to bigger problems over time.
CRISPR, a gene-editing tool, offers an efficient way to make precise changes to crop genomes, potentially avoiding the need for foreign genes and reducing the environmental impact associated with herbicide use.
Regulation and Broader Issues
GM crops are mainly developed by large companies, raising concerns about monopolies and environmental control.
High costs of regulating GM crops limit alternative, non-profit-driven agricultural solutions and the development of more sustainable practices.
Limited research on GM crops’ long-term biodiversity effects makes it difficult to assess their full environmental impact, as agriculture itself has inherent risks.
