Does human activity harm our planet?

With the use of fossil fuels in everyday machinery being used constantly, we produce carbon dioxide that pollutes the air. Humans are a direct cause of global warming. We've caused climate change that has increased Earth's temperature by 1.5 degrees Fahrenheit and is expected to rise between 0.5 to 8.6 degrees in the next hundred years. Climate change doesn't just affect the Earth but everyone and everything on it. Animal migration, food supply, energy, and the environment can be affected by the climate. An example is from "The Day After Tomorrow": due to increased heat caused by greenhouse gas emissions, the natural weather patterns of the Earth shifted. This resulted in cooling by altering wind patterns. In the movie, this climatic shift caused massive bird migrations.

Fossil fuels are a constant resource that humans use for transportation, electricity, and factory production. Most people commute in cars, which use gasoline (a fossil fuel). carbon emissions from the cars pollute the air. `this polltion is Also known as greenhouse gases, which absorb radiation and heat up the Earth causing global warming.

As shown in the chart above, the temperature of the Earth has risen over the past 95 years when the Earth was balanced at around 0 increase. Humans are the cause of this increase in temperature and will continue in the coming years if greenhouse gases continue to be produced.

  1. I like the visuals, particularly the 2nd one. It provides some real data to back up your words. One thing to keep in mind: you should always cite the sources of your data, such as that plot. Who made it? Where could I find more about it?
