Global Warming: an International Problem

Global warming is the increase of temperature in the planet. It is majorly caused by human interference in the natural environment, such as the degradation of the ozone layer, resulting in more absorption of the solar rays. This rise in temperature affects the entire Earth’s surface, but the focuses of the phenomenon are the population centers, like the megalopolis. It began in late 19^th century and is projected to continue, if not prevented. The importance of this topic is unarguable, as it will influence people from the entire world.  It is a subject that everyone should be aware of and because of that possible solution may be reached.

The main cause of global warming is the high concentration of greenhouse gases produced by humans on the atmosphere. These gases absorb and emit thermal radiation to the surface, which in excess, contribute to the temperature rise. Another important cause for the warming is the burning of fossil fuels that generate a vicious pollution for the atmosphere, creating holes in the ozone layer, destroying an important Earth’s natural defense.

Consequences of such event are the melting of the ice caps in the poles, occasioning disturbs in the ecosystems of these areas, such as higher sea level and the destruction of the natural habitat for some of the pole species, like the polar bear and the penguins. The rise of temperature may also result in problems on the agriculture sector, the solar rays may increase the exfoliation, a phenomenon that leaves the soil on an inappropriate state for planting.

To find a solution for global warming is a hard task, as it is a worldwide problem, in which almost all nations are involved. The easiest way to decrease the effects on the environment would be to reduce the pollution released in the cities. This would be done by creating a way to filter industry’s chimneys and reducing the amount of carbon dioxide sent to the atmosphere. Another possible solution would be the popularization of sustainable cars, this would also reduce significantly the emission of pollutants.

To sum up, it is already proved that the global warming is something serious, it is already possible to feel some of its effects. With that in mind, the population from all around the world should start to treat it with more seriousness. If everyone does his part, the situation will get better. The government should also do its part and include sustainability in its ideals for a better world. This is a problem for everyone, and it should be fought by everyone.
