Why Environment changes?

The changes in environment occur due to the human actions.  Long-term changes in temperature and weather patterns are referred to as climate change. These changes may be organic, but since the 1800s, human activity has been the primary cause of climate change. This is mainly because burning fossil fuels, such as coal, oil, and gas, releases gases that trap heat.

Due to the human actions either heat increases in the atmosphere or different dangerous gases increase and pollute the air, which in turn causes temperatures to rise slowly.
