Many countries in the world are already experiencing the impact of global warming through drastic changes in climate, temperature, and physical geography of the planet. According to experts, climate change will result to increased tropical cyclone activity, increased incidence of extreme high sea level, and increased in areas affected by drought. These changes will have negative impact in the social and economic conditions of many nations in the world. Temperature and geographical changes in the world will not only affect humans but also animals and plants too. Many humans will migrate to find more conducive place to live and many animals and plants will face extinction if they will not adapt to the sudden changes in their physical habitat.

Global warming is largely attributed to human activities in the past and at the present. We have been dumping large amount of carbon dioxides in the atmosphere for many years. These carbon dioxides and other greenhouse gases are considered to be the causes of global warming. If you think that only large factories emitting gases to the atmosphere are causing global warming, you are wrong. Everyone of us is involved in global warming. As long as we use electricity and petroleum products, we are contributing to global warming.
