ARTICLE: When Olafur Eliasson and Frederik Ottesen heard that more than 1 billion people on Earth don’t have access to electricity, they wanted to help. In many places, lack of electricity means students can’t study after dark and families can’t cook after the sun goes down. It’s also harder for doctors and nurses to treat patients without good lighting. Eliasson and Ottesen decided to invent a solar lamp that would provide light without costing a lot of money, polluting the air, or causing fires.
Their solution? The Little Sun lamp is a sun-shaped light with a light bulb on one side and a solar panel on the other. The Little Sun lamp uses energy to provide light to people who need it, but the Little Sun doesn’t make its own energy. To run, the lamp needs to get energy from somewhere else. In this case, that source of energy is the sun. The solar panel on the back of the lamp converts light energy from the sun into potential energy that can be stored in a battery and used later to make the light bulb shine. Little Sun lamps charge in the sun during the day and provide light at night, allowing people to study, cook, work, and take care of other things even after the sun sets. They’re inexpensive, don’t pollute, and don’t cause fires.

questions: 2) How does the Little Sun Lamp help people around the world get light?

3) How does the Little Sun Lamp use energy from the sun to make the light bulb shine?

according to the u.s. department of agriculture, the label of "certified organic" comes with a set of highly regulated standards for environmental stewardship and resource conservation. some of these include maintenance and improvement of soil quality, prevention of ground and surface water contamination, greenhouse gas regulation, encouragement of biodiversity and conservation of water and energy (see references 1). organic practices integrate natural methods such as mulching, plant diversity, native and adapted plants, crop rotation and the introduction of beneficial insects to control pests without synthetic pesticides.

environmental implications of pesticides

synthetic pesticides ensure high crop yields. while effective in achieving this goal, pesticides contaminate soil, air, ground and surface water, as well as the plants and animals that come into contact with these contaminated sources. freshwater and marine organisms are particularly susceptible to pesticides through agricultural runoff. pesticides also reduce soil fertility (necessitating the use of synthetic fertilizers) and can travel far from the original source, contaminating water and air hundreds of miles from the location of application (see references 2).

health implications of organics

although a subject of particular debate, many recent findings show that organic food is healthier than conventionally grown food. according to the usda, an extensive european union-funded study found that organically grown foods contain more beneficial compounds, such as the vitamins and antioxidants needed to combat many diseases (see references 5). organic milk, meat and eggs are regulated to ensure they are free of hormones administered to conventional livestock and poultry.

health implications of pesticides

pesticides affect human health in three ways: through skin contact, inhalation and ingestion. acute and long-term exposure to pesticides can cause serious health problems for farmers who apply them. the majority of other people are affected by drinking contaminated water and eating contaminated marine life (see references 3). pesticides have been linked to neurological disorders, endocrine and reproductive disorders, immune system deficiencies and cancer. according to the world health organization, acute pesticide poisoning (app) is responsible for significant annual mortality, especially in developing nations (see references 4).

other important considerations

not every small farm or business owner can afford the costly certification process required to be considered "certified organic," even if the farm is not using chemicals. "transitional" farms include those that once used chemicals and are now transitioning to organic-only production. in addition, though organic farming methods offer obvious environmental benefit, an organic apple shipped from around the world creates a different set of environmental problems. locally grown food (particularly locally grown, organic food) is key in sustainable food production.
