4. Causes of global warming!!!!

5. Effects of global warming ● As the temperature increases the water level also increase due to high temperature.

6. Effect of global warming ● An increase of tempeature also leads to change of climates.

7. How are humans contributing to global warming?? ● Humans contributing by littering and driving cars and filling the atomsphere with co2. ● Also by deforestation and that also leads to more co2 in the atomsphere. ● Building factories,homes,and,buildingthey all lead to the same thing an increase of co2 in the atomsphere.

8. How do humans cause global warming

9. ● Humans are one the major reason why global warming is ocuring right now. ● They cause most of the global warming by causing pollution and deforestation and building factories.

10. Solution for global warming... ● One solution can be the three R's which are recycle,reduce,and reuse these can be used to reduce global warming. ● Plant more trees so they can take in most of the co2 in the atomsphere too cool down the earth. ● Instead of using cars you can ride your bike or you can use public transportation vehicles.
