International Dark Skies Week
April 13-19, 2015 in the World
In mid-April (13-18 April) people from around the world will turn out their lights in an attempt to bring back the night sky for International Dark Skies Week. In most cities, the light pollution is so intense that the band of stars which stretches across our sky, we know only from books and pictures as the Milky Way. The International Dark Skies week was created to bring awareness to the loss of our starry night, and spread the word about how we can combat the effects of light pollution to bring back the dark night, not only for astronomy but for better managing our energy usage, protecting ecosystems and helping our own safety and health.
Light pollution interrupts natural circadian rhythms in humans, plants and animals. Melatonin is a hormone that is naturally released during prolonged periods of darkness. The presence of light can interfere with its production, especially blue light, like the light that comes from computer and phone screens. The International Dark Sky committee is proposing that red light is used, it’s at a lower wavelength, therefore, has the least impact on night vision and also decreases loss of melatonin. In humans, melatonin loss can lead to stress, weight gain, insomnia and depression. Animals decline in population due to interrupted mating cycles and migration patterns and predator and prey interactions for nocturnal creatures are disrupted. Light pollution also effects nocturnal insect pollination and hinders regulation of plant growth and root formation.

International Plant Appreciation Day
April 13, 2015 in the World
International Plant Appreciation Day takes place on April 13, 2015. Plants are living multicellular organisms of the kingdom Plantae. They form a clade that includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts and mosses, as well as, depending on definition, the green algae. Plants exclude the red and brown algae, and some seaweeds such as kelp, the fungi, archaea and bacteria.
Much of human nutrition depends on land plants, either directly or indirectly. Human nutrition depends to a large extent on cereals, especially maize (or corn), wheat and rice. Other staple crops include potato, cassava, and legumes. Human food also includes vegetables, spices, and certain fruits, nuts, herbs, and edible flowers. Beverages produced from plants include coffee, tea, wine, beer and alcohol.
Thousands of plant species are cultivated for aesthetic purposes as well as to provide shade, modify temperatures, reduce wind, abate noise, provide privacy, and prevent soil erosion. People use cut flowers, dried flowers and houseplants indoors or in greenhouses. In outdoor gardens, lawn grasses, shade trees, ornamental trees, shrubs, vines, herbaceous perennials and bedding plants are used.
