Global warming is a boiling issue to the world. There are many causes that leads to global warming. The massive use of fossil fuels is obviously the first source of global warming, as burning coal, oil and gas produces carbon dioxide - the most important greenhouse gas in the atmosphere - as well as nitrous oxide. Another cause of global warming is intensive farming, not only with the ever-increasing livestock, but also with plant protection products and fertilizers. In fact, cattle and sheep produce large amounts of methane when digesting their food, while fertilizers produce nitrous oxide emissions. Possible solutions for those causes include finding green alternative sources of energy and eco-farming.

Global warming is due to the release of excessively high amounts of methane from the Arctic and wet regions. Methane is the greenhouse gas that holds the heat. So, we need measures like:

1. Minimize waste and recycle them
The burning of many types of waste increases the level of carbon dioxide in the atmosphere and carbon dioxide is a major contributor to the greenhouse effect and global warming. So we should choose products that can be reused rather than thrown away.
2. Less driving reduces global warming
Less driving means less emissions. Besides saving on gas, walking and cycling are great forms of exercise.
3. Growing plants to reduce global warming
During photosynthesis, plants and other plants absorb carbon dioxide and release oxygen. A single tree will absorb about a ton of carbon during its life cycle. Plants are an integral part of the natural atmosphere exchange cycle here on Earth
