Do human activities damage our planet, or do they make it a better place to live in? Our planet has being threatened by human activities approximately since the Industrial Revolution, in the 19th century, which has contributed to expand the greenhouse effect. From this time on, humanity has massively increased the gases that are sent to the atmosphere due to better life conditions, allowing people, from all over the world, to use certain new objects and energies that damage the suitability of planet Earth. In the last ten years we assisted to an increasingly global warming, meaning that temperature is changing, affecting the whole world, namely the developing countries that may face severe famine and, as a result, the proliferation of certain diseases due to their camps, that are becoming dryer, as they sustain several individuals. In addition, human activities also affect the lives of some species (deforestation), the glaciers, which are melting in a larger rhythm, or the acceleration of the ocean acidification. Nevertheless, human activities also can contribute and improve life conditions and give our world a complete transformation, turning it more secure and productive, since people are becoming more and more ambitious. However, we need to respond to certain questions, is our planet capable of handling our life standards? Couldn’t we live without some of our possessions? Aren’t we able to balance developing and developed countries standards of living without damaging even more our planet? In conclusion, people must make an effort to use their home-energies effectively through recycling, sparing water, etc.; and, concerning economic activities, for instance agriculture, industries, they must try to do the same. If we act together, and invest on clean energies we will be able, in the future, to balance our life standards with a sustainable development.
