In the first video «Environment - protecting our habitat resources» we can see a team of scientists from the University of Sheffield. They are talking about our environment. They said that the biggest challenge we face is how to feed all people without doing yet more damage to the environment, and that finding a solution for it –is absolutely vital and is really a daunting task . Although, scientists consider that one of the key challenges that are faced by mankind at the moment is the issue of climate change. At the University they are working very hard and in innovating way by developing new technologies and systems. Scientists start big research project in order to answer big research problems. They are talking about different alternative and renewable energy sources, which will conserve and save energy. For example, they are discussing solar energy, they try to understand the sun, how we collect energy from the sun.
In the second video «Seed communities: Eco-village Experiments Around the World» we can hear an interview with Professor Karen Litfin, University of Washington. She’s studied the pollution, climate change, deforestation and other big issues. She wanted to see who is trying to live sustainably. She is telling about eco-villages — small, self-contained communities that are trying to live ecologically. Karen did intensive research in 14 of eco-villages around the world. She looked the eco-villages from four different prospectors: how they live ecologically, economic aspects, how they share or do not share their money and community aspects. Furthermore, she also mentioned drawbacks of eco-village life. In addition, she said that we don’t need create eco-villages, we just need to take the basic principle of living and apply them to our lives where we are here today.
