Humans Cause Global Warming
Storyboard Text
- Various activities such as the burning of natural gases for energy, agricultural practices and the clearing of land for urban development has helped increase Earth's global average temperature to dangerous levels
- In order to develop homes, humans rapidly clear forests which results in more carbon dioxide into the atmosphere sink there are no longer trees to function as sinks for carbon
- Scintists argue that in the last millennia humans have altered three quarter's of earth's land surface for development.
- Over the past century, the burning of coal, oil and other natural gases in factories has increased the amount of CO2 flowing into the atmosphere
- the clearing of land for crop production and the current food system results in increased C02 into the atmosphere
- Practices of agriculture result in the release of anthropogenic emissions like methane and nitrous oxide into the atmosphere
- The increase in average temperatures has already created various environmental hazards such as forrest fires, with increased intensity.
- This melting is harmful to various ecosystems that depend on glaciers for their habitat. Many species may go extinct as a result of this
- Global Warming driven by humans has also lead to the melting of glaciers at a rapid rate.
