2. Introduction We all live in a beautiful place called planet earth. In the beginning there was a balance between the humans and nature. But as time went by, the human race developed so much that it started to upset the balance, causing serious problems such as global warming, deforestation, pollution and many others.
3. Global Warming Global warming is being caused essentially by the emissions of gases such as CO2 and CFC’s. CO2 is one of the most important greenhouse gasses. This type of gasses can absorb solar radiations. Currently the emission of gasses to the atmosphere is rising what causes a stronger greenhouse effect, that causes this issue.
7. The list of problems goes on and on and on… So, what can we do?
8. What can we do to save our planet? Start using renewable energy Renewable energy is the energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat. They are naturally replenished.
9. What can we do to save our planet? Recycle Used materials that are transformed, giving rise to new materials

11. What can we do to save our planet? Change your lightbulbs Replace incandescent bulbs with fluorescent bulbs
12. What can we do to save our planet? Pay the carbon tax Limit the level of carbon that can be emitted by an industry
13. What can we do to save our planet? Let employees work close to home AvoidsWaste of time and the planet's fuel
