Yes, global climate change is definitely man-made. The most prominent reason is that most of the energy we depend on is coming from the fossil fuels and its burning produced carbon dioxide, the main cause for global climate change. Another reason is that forests are disappearing because of many purposes for human life. Without strong change in our energy source and use, global climate change will get worse.
Pollution Caused By Building a Hybrid Car
PREV NEXT
Building a hybrid car is almost exactly the same as building a conventional car, requiring high-tech and highly automated assembly lines. This type of manufacturing process requires tremendous inputs of energy, particularly the forging of materials like steel, aluminum, glass and plastic. Interestingly, lightweight vehicles can sometimes be more energy-intensive to build than heavier cars because lighter metals like aluminum are harder to forge than stainless steel [source: Moon]. Experts estimate that 10 to 20 percent of a vehicle's total lifetime greenhouse gas emissions are released during the manufacturing stage alone [source: California Energy Commission].
Toyota admits that the production of its lightweight Prius requires more energy and emits more carbon dioxide than the production of its gas-only models [source: Williams]. The major reason is because hybrids like the Prius include more advanced components than a conventional car, including a second electric motor and heavy battery packs.
