**Implications of Genetically Modified Organisms (GMOs) on Food Security and Biodiversity:**
1. **Increased Crop Yields**:
– GMOs can enhance agricultural productivity by creating crops that resist pests, diseases, and challenging environmental conditions. This results in higher yields and more reliable food supplies, thus improving food security.
2. **Reduced Use of Agricultural Chemicals**:
– GMOs often require fewer pesticides and herbicides, leading to lower production costs and reduced environmental pollution. This benefits both the environment and food security by minimizing chemical usage.
3. **Biodiversity Issues**:
– The extensive use of GMOs can lead to the dominance of specific crop varieties, which might reduce genetic diversity in agricultural systems. This reduction in diversity could make crops more vulnerable to new pests or diseases and negatively affect overall biodiversity.
4. **Gene Flow and Resistance**:
– GMOs may interbreed with wild or non-GMO crops, potentially creating “superweeds” or causing unintended ecological effects. Furthermore, pests and weeds may develop resistance to GMO traits, necessitating new control measures.
5. **Economic and Social Effects**:
– The introduction of GMOs can alter market dynamics, including the consolidation of seed companies and impacts on smallholder farmers. Intellectual property rights related to GMOs may affect farmers’ access to seeds and their autonomy.
In summary, while GMOs provide notable advantages for food security through increased productivity and reduced chemical use, they also present significant concerns regarding biodiversity and long-term ecological effects.

Human activities such as unregulated construction and tourism have heightened the risk of natural calamities in ecologically fragile regions like Kedarnath. Rampant construction without proper appraisal of environmental impact has resulted in deforestation and soil erosion, and has also interfered with natural water drainage systems, increasing the susceptibility of the area to landslides, floods and other natural disasters. The devastating Kedarnath flood disaster in 2013 brought this into focus when haphazard buildings and roads compounded the loss of lives and property.
Tourism though economically beneficial, has caused too much environmental degradation in the region. The inflow of visitors makes it necessary to put up a lot of infrastructure which in turn consumes large tracts of natural habitats and also generates more waste, thus polluting the environment further.
To achieve sustainable development in such regions, it is of primary importance to enforce environmental laws. Construction in general, must be limited and if at all undertaken then only using eco-friendly practices. Similarly, promotion of eco-tourism involves locals and reduces environment impacts. Reforestation should be promoted at construction sites, waste should be properly disposed off and sustainable construction materials should be used.
