Conclusion

Global warming is now affecting weather, plants, animals and people. Humans are warming the earth's atmosphere by burning fuels and cutting down forest. If we stop producing CO2 by switching oil, coal, gas to renewable energy, the global warming could stop. Another solution is to plant more trees. Also electricity is one of the main sources of carbon dioxide so using less electricity will produce less CO2. Trees absorb carbon dioxide and produce oxygen which is not a greenhouse gas. If we make the small changes in the way we live, we can avoid global warming problems in the future.
