Climate change may refer to a change in average weather conditions, or in the time variation of weather around longer-term average condition. Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruption. Certain human activities have also been identified as significant causes of recent  climate change, such as

  • Over population
  • Huge uses of pesticides in agricultural field
  • Deforestation
  • uses of more petroleum product in daily life

“We are facing rapid changes in the global climate, and these changes are attributable to human behaviour. Humans produce this global impact through our use of natural resources, multiplied by the vast increase in population seen in the past 50 to 100 years.”(Janet K. Swim, Susan Clayton,George S. Howard)over population in china Human overpopulation,Jody McCutcheon

“Most human infrastructure elements are insensitive to climate change, except some such as agriculture, hydro-power production, and transportation in marginally navigable rivers. Demand for air conditioning will increase, but demand for space heating will diminish.”(Eugene S. Takle,1997)


Many people are uneducated about climate change, don’t believe their actions can make a difference. Furthermore, those who do try to act to protect the environment don’t always do so effectively.If humans don’t change their behaviour from today than we should have to be ready to face heavy climate change and global warming.
