Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and oceans. A changed that is believed to be permanently changing the Earth’s climate that cause and effect for global warming. Almost 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of greenhouse gas concentrations like water vapor, carbon dioxide (CO2), methane and ozone. Greenhouse gases are those gases that contribute to the greenhouse effect. The largest contributing source of greenhouse gas is the burning of fossil fuels leading to the emission of carbon dioxide. Global warming will cause numerous problems to the environment, which in return will hurt the human population. All of these things will make survival harder for the human race in the very near future. Global warming will have many effects on plant life. The warming of our planet will make landscape harsher, which will make it harder for plants to grow and survive. If there aren’t any plants or animals then we will have a shortage of food and many people will die from starvation. Finally, I think we should have save the world to the save life.
