Environmental Policy and Sustainability
Many things which are done by the school and students promote sustainable living as, schools can be foundations of information and experimentation in sustainable living. They have an idea to discover how to do new things, and they have students who have the energy or power and passion to do much of the research, and for whom that discovery will be a costly learning knowledge. Many collage and universities provides the campus for students have inspections to examine the following examples of sustainable resources utilization: 1. Water and energy use. 2. Waste production and removal or dumping. 3. Paper use. 4. Recycling. 5. Buying nearby produced food.
The photovoltaic cell: In general the photovoltaic cell is a convertor, which converts solar energy into electric energy. The photovoltaic cells are those devices that lock-up the solar energy and converted it directly into electric current. The photovoltaic cells work by capturing the electrons form the solar energy and transport the captured electrons by one-way electrostatic barrier formed in between the two different types of semiconducting materials.
International environmental conventions and treaties are often ineffective because of following reasons: 1. Several developing countries need the capacity to tackle specific environmental issues effectively. 2. Issues are tackled in different methods by different countries. 3. Approaches of individual countries may also be predisposed by differences in technological status. 4. A country with now increasing industries and a struggling economy may well refuse to apply certain measures as they would have a negative impact on their increasing industry and their financial system. 5. Their approach could be that they cannot be detained liable for the mistakes made by industrialized nations, and those industrialized, wealthy nations should contract with the problems. 6. Over and over again rich countries decline to allow and implement necessary measures because it may actually expense them some of their millions to improve things. Some methods to improve the international environmental conventions and treaties are as follows: There are mainly two methods in which the international environmental conventions and treaties can be made more effective. • One is to require authorizations on countries who can offer to make changes and have the technology to do so, but refuse because they do not want to spend the money. • Second is each person will be on the equal level and working from general ground for a common aim, namely to protect what is left of the world for future generations.
