1. Greenhouse Gas Emissions
   The primary driver of global warming is the accumulation of greenhouse gases (GHGs) such as carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O). These gases trap heat in the Earth's atmosphere, creating a “greenhouse effect.”

2. Deforestation
   Forests act as carbon sinks, absorbing CO₂ from the atmosphere. When trees are cut down for agriculture or urban development, stored carbon is released, and fewer trees remain to absorb future emissions.

3. Industrial Activities
   Factories, power plants, and vehicles emit large quantities of greenhouse gases. Industrialization has accelerated global warming since the 19th century, with emissions increasing dramatically.

4. Agriculture
   Livestock farming produces methane, while fertilizers release nitrous oxide—both potent greenhouse gases.

Effects of Global Warming

1. Rising Sea Levels
   Melting glaciers and ice caps, along with the thermal expansion of seawater, contribute to rising sea levels, threatening coastal cities and small island nations.

2. Extreme Weather
   Global warming intensifies hurricanes, droughts, heatwaves, and heavy rainfall. These events disrupt food supplies, destroy infrastructure, and displace populations.

3. Loss of Biodiversity
   Changing temperatures and habitats put stress on wildlife, leading to extinction or forced migration of many species.

4. Human Health Risks
   Heatwaves, water scarcity, and the spread of vector-borne diseases like malaria are becoming more common due to climate change.                                              So lets make a change and pollute less by not turning the lights ,AC's ,and other things which produce green house gases on unnecessarily.
