3º CC.SS. - TEMA 9 - Sustainable development

Sustainable development
Sustainable development has been defined in many ways, but the most frequently quoted definition is from Our Common Future, also known as the Brundtland Report:
"Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It contains within it two key concepts: the concept of needs, in particular the essential needs of the world's poor, to which overriding priority should be given; and
the idea of limitations imposed by the state of technology and socialorganiSationon the environment's ability to meet present and future needs."
The way we approach development affects everyone. The impacts of our decisions as a society have very real consequences for people's lives. Poor planning of communities, for example, reduces the quality of life for the people who live in them.
Sustainable development provides an approach to making better decisions on the issues that affect all of our lives.

Environmental problems
Our environment is constantly changing. There is no denying that. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters, warming and cooling periods, different types of weather patterns and much more, people need to be aware of what types of environmental problems our planet is facing.
1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle are the number one pollutants.
2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases.
3. Waste Disposal: The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans.
4. Climate Change: Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels.
5. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and loss of biodiversity.
6. Water Pollution: Clean drinking water is becoming a rare commodity. Water is becoming an economic and political issue as the human population fights for this resource.
