Model Answer
Cyclones, despite their destructive power, have several beneficial environmental effects that contribute to ecosystem balance and the well-being of geographical regions.
1. Rainfall in Drought-Prone Areas
Tropical cyclones are efficient at generating rainfall, which can relieve drought conditions. For example, Tropical Storm Debby helped eliminate a drought in the southern United States, bringing much-needed water to parched areas.
2. Red Tide and Bacterial Disruption
Cyclones break up harmful bacteria and red tide through strong winds and waves that mix ocean waters. This oxygenates the surface waters, enabling marine life to return. A notable example is the disruption of red tide along the Gulf Coast of the USA.
3. Global Heat Balance
Cyclones help regulate the Earth’s climate by moving warm tropical air to mid-latitudes and polar regions, contributing to the global heat balance. After Hurricane Blas, cooler waters were left behind in the Eastern Pacific, stabilizing the region’s temperature.
4. Climate Change Mitigation and Mangrove Growth
Cyclones also enhance the growth of mangroves by providing more nutrients and freshwater, aiding carbon sequestration. In India, tropical storms have positively impacted mangrove ecosystems by boosting their ability to fix carbon dioxide.
5. Replenishment of Inland Plant Life
Cyclonic winds and rainfall disperse seeds and nutrients inland, facilitating plant regeneration. This supports biodiversity and aids in restoring ecosystems disturbed by urbanization. For instance, hurricanes have contributed to the growth of tropical hardwood hammocks in South Florida.
6. Recharge of Groundwater Aquifers
The intense rainfall from cyclones can recharge groundwater aquifers in arid regions. Cyclones have helped replenish aquifers in areas like Chamarajanagar district of Karnataka, India.
7. Ecological Succession
Cyclones reset ecosystems by defoliating mature trees, allowing sunlight to reach the understory. This fosters the growth of shade-intolerant species, contributing to ecological succession and biodiversity.
In conclusion, while cyclones can cause widespread damage, their ecological benefits are significant, fostering biodiversity, climate regulation, and resource replenishment across ecosystems.

There are various speculations regarding the next World War, i.e., World War 3. Many world leaders, often mention that we are in a grave situation already, and a few mistakes away from triggering a world war. It is usually debated that the next world war will be fought using deadly forces like atomic weapons, chemical weapons, and biological weapons.
There are more than twelve thousand nuclear weapons across the world now. Just two atomic bombs in Hiroshima and Nagasaki in Japan during the Second World War brought a nuclear winter after destroying millions of lives. Even if just 100 current-day atomic weapons were used in the Third World War, it would be a catastrophe for the environment, causing irreversible changes to our climate. An increase in temperature, atomic dust and subsequent high radiation clouds spreading miles and miles will make our atmosphere impenetrable to sunlight. This might usher in another ice age, causing an extinction-level climate change.
Similarly, using deadly chemicals may pollute our rivers, destroying aquatic flora and fauna. Such acts will bring ecological imbalance and eventually will cause major climate change.
Biological weapons, similarly can be harmful not only to humans but also other species. Such warfare will also destroy ecosystem homeostasis. The next world war will be bad for the climate.
