Acid rain - Assignment Example
Sulphur dioxide and nitrogen oxide, which are dangerous gases produced through burning fossil fuels undergo intricate chemical reactions when they come into contact with water to cause acid rain.4 Adopting the use of low-carbon or even zero-carbon energy sources such as solar will therefore help prevent acid rain in future.
Innovations have also contributed to an increase of carbon dioxide in the atmosphere which transforms into acid rain. For instance, Casper asserts that motor vehicles are some of the largest contributors of carbon dioxide in the atmosphere.5 In this respect therefore, future developments in creation of motor vehicles and other motorized engines that produce less carbon dioxide will help eradicate acid rain. For instance, Casper notes that major universities in the U.S. and Canada started experimenting with solar powered motor vehicles as early as 2005.

Danger to Bees is Danger to Us - Research Paper Example
Besides, when bees feel threatened, depending on their strain they can sting once and in some cases respond to threats in great numbers and even can pursue intruders with more persistence. Bees remain the significant commercial pollinators of crops that rely on animal pollination which account for 35% of world food production (Genersch 87). Therefore, bees are vital for economic and sustainable agriculture as well as food security; hence, their threat translates to human threat. For instance, honeybees and their health has been a major topic in the recent past considering their significant role in pollination and food production. Although some exaggerated suggestions claim that humankind would not survive long if bees disappear, production of many fruits and crops that contribute to healthy diet rely on animal pollination.
