Video 1: “Ways to Save the Planet: Space Sunshield (2009)” Source: www.yourdiscovery.com/web/ways-to-save-the-planet/ Created by Discovery Channel, this video shows the project of Professor Roger Angel in which he attempts to deflect the sun's rays by blanketing the earth's atmosphere with ultra-light and ultra-thin lenses. These lenses are designed to deflect 2% of the sun's energy away from the earth, thereby reducing the earth's temperature to levels similar in the pre-industrial period…
The goal is to create 16 trillion pieces of lenses that are 1 micron thick and 60 cm in diameter. These lenses are expected to cover 100,000 square miles of the earth's atmosphere. So far, Dr. Angels has created a 5-cm thick glass refractor which is tested by etching a diffraction pattern in it and subjecting it to a laser beam. To test if the lenses can withstand the pressure of a rocket launch, a test launch powered by electromagnetic propulsion was conducted. On-board cameras were installed to capture images of the lenses as they launch into space. Unfortunately, at 900 meters into the air, the craft carrying the lenses failed and crashed. This video shows how the interaction of physical sciences like physics and engineering works to mitigate the effects of global warming. Through physics, a refracting lense etched with a diffraction pattern is created. Through engineering efforts, meanwhile, the task of getting these refracting lenses into space can be accomplished. If successful, these technological efforts can yield ways and means of saving our planet. ...

It follows that wherever large amounts of money collect, so also new centers of power form. The latest historical manifestation of this is the modern corporation. As trillions of dollars accumulate in the corporate sphere, we witness the growing power of corporation to shape the world as they see fit.
Environmental science encompasses issues such as climate change, conservation, biodiversity, water quality, groundwater contamination, soil contamination, and use of natural resources, waste management, sustainable development, disaster reduction, air pollution, and noise pollution.
Such measures may include good governance, emphasis on education, and zero tolerance on corruption and so on. But for the purpose of remaining relevant to our topic we are going to dwell on demographic transition and its impact on any given country. Demographic transition is a process said to have began 300 years ago (at the turn of the 18th century) in Britain and France before it spread to Europe and other continents (Poston, 2006).
It should be noted that many farmers have already switched and more are switching to the IPM principles; therefore, introducing incentives will disadvantage these sets of farmers (Chiras, 2013). Moreover, it should be noted that farmers are usually very conscious to their land stewardship; hence, any environmental and economic shown to them usually drive them to changes without any incentives.
While pollution causes illness and death among human beings the loss of biodiversity adversely affects the entire ecosystem. Renewable sources, on the other hand, can reduce environmental pollution to a great extend in comparison with the large scale pollutions from the over use of non-renewable energy sources.
Signs all around us are screaming to make us come to our senses and act before it is too late. This, ladies and gentlemen, is the reason for our gathering here today. We are one of those privileged few who have heard these cries and have taken it upon our shoulders to promote the awareness needed in modern man to save the very place which has nurtured us and which we are destroying at a very fast pace.
These rocks melt to form molten lava which is spewed out during volcanic eruptions as magma. When magma crystallizes it forms igneous rocks. Igneous rocks on weathering or due to erosion and deposition form sediments. These sediments
The United States is capable of attaining the set targets. Furthermore, it can also aid some of the other regions in attaining their food security objectives. The technology present in the United States helps in growing foodstuffs that would otherwise not have made it
Thus it is very vital to join the green revolution movement in order to be at the front in finding an alternative of kind of energy used even in our homes. The first step involves identifying energy uses in
