Global warming is a very broad subject. The official definition of global warming is an increase in the Earth's average atmospheric temperature that causes corresponding climate changes and may result from the greenhouse effect. I translate this as the warming of the earth; it could be caused by people. Personally, I think that global warming is caused by humans. Some processes that contribute to global warming are factories, cars, and many other objects that produce carbon dioxide. Global warming affects each of us. The earth is warming up and melting all the ice and glaciers. This is very bad for animals and humans. The effect we are having on this Earth is becoming a bigger problem than we can handle. Greenhouse gases are one of the main causes of global warming. The population is increasing every day. This means that greenhouse gases are increasing. Indeed, the denser the population, the more devices producing greenhouse gases are used. The more our population evolves, the more advanced it becomes. Our cutting-edge technology produces vehicles. About 15% of human-produced carbon dioxide comes from vehicles. Vehicles produce chlorofluorocarbons and other gases that cause smog and air pollution. When this odorless, colorless, non-toxic gas enters the atmosphere, it can destroy the ozone layer. Many toiletries are also thrown into landfills and pollute the earth. Products that do not contain certain harmful gases can sit in landfills for years and pollute the earth and atmosphere. Greenhouse gases, created by overpopulation, vehicles and waste disposal, are one of the main causes of global warming. Global warming is caused by humans. Since our population is in the middle of paper, it is used daily, as well as recycled. Personally, recycling makes you feel important. Just putting a piece of paper in the recycling bin can make a difference for everyone. The economy would also be affected. This is because the more materials we reuse, the less we have to produce, which saves money. Recycling is a very simple way to influence our world. Man-made materials are causing global warming. With carbon dioxide increasing, there is only one explanation: our materials. The objects we use produce gases that are harmful to the environment. The great thing is that there are many possible solutions such as: car sharing, energy efficient homes and recycling. At the beginning of my research, I was rather hesitant about whether global warming was natural or man-made. By the end of my research, I completely decided that global warming was man-made..
