82% OF STARVING CHILDREN LIVE IN COUNTRIES WHERE FOOD IS FED TO ANIMALS, AND THE ANIMALS ARE EATEN BY WESTERN COUNTRIES. Livestock or livestock feed occupies 1/3 of the earth’s ice-free land.

Name at least 3 renewable energy sources. What consequence might there be if we use non-renewable energy too much? Which energy technology is the world's fastest growing? With what name is renewable energy also known as? Light Heat Electricity Generated from natural resources. Doesn't harm the environment. Can't be replenished Most of our energy. May cause global warming. Wind energy is the fastest growing. Most renewable energy comes from the sun. Hydroelectric energy is the oldest and largest source. Renewable energy a.k.a "green" energy. Thank you for listening! We use energy every day. It surrounds us in different forms, such as light, heat, and electricity. Our bodies use the energy stored in molecules of substances like carbohydrates and protein to move, breathe, grow, and think. We also use energy to do work and to play. Humans have invented thousands of machines and appliances that use energy
And still there are people who won’t listen to the government rules and spread the virus further. Secondly, global warming is increasing at an alarming rate with the progress in technology. In recent years, industrialization and extensive use of automobiles have been observed, and these developments have significantly raised the levels of greenhouse gases in the atmosphere. Moreover, these gases like carbon dioxide and methane trap the sunlight and elevate the temperature of the earth. This change in temperature is not only responsible for global warming but also other associated problems of climate change and air pollution. In conclusion, to ensure positive contributions and to minimize risks to the planet, relying on govenment alone will not lead to the desired results. Each person's effort can effectively help protect the environment.
Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted our world as we know it is changing. Some scientists believe that the climate will reach a tipping point, a point at which even a tiny additional increase would throw the system into violent change. We started doing harmful things and only now do we realize what we have done and what we are doing. At this current rate by the middle of next century the Earth's temperature may
Humans are changeing the planet with their ordinary life. The principle cause of climate change is the increase in carbon dioxide concentrations in the atmosphere. The main cause of that is the burning of fossile fuels. This is leading to the global warming. People have discovered a way to reduce the amount of CO2 in the atmosphere. It is possible to seperate the CO2 from the other gases by adding liquid which is very good at absorbing CO2. Then it can be pumped to underground. Scientist came up with this idea because methane gas has been
In 2009 we had 407 cars to thousand inhabitants, which is lower than European Union average, but this number is still high. Because cars produce gases that contain carbon dioxide. This carbon dioxide in the air causes global warming, which is the result of the greenhouse effect. Tallinn wants to fight against it by offering public transportation for free, to Tallinn citizen. So that people would use more public transportation than their own car. Furthermore, it will change our climate. In addition our air is polluted by hydrogen sulfide from plants and factors (Especially in Kohtla- Järve and Maardu). Other big environment problem is garbage. Huge amount of waste is produced every day and it is all because of overconsumption. Although, in recent years peoples knowledge about recycling and using eco-friendly products have improved, there are more landfills in Estonia than ever before. The government should take some actions and instead of talking about
One of the most significant events, possibly the very most significant event, of the 19th century was Maxwell's discovery of the four laws of electrodynamics ("Maxwell's Equations"). This led to electric power, radios, and television. 1763-1774 Pumping water from coal mines was a most difficult and expensive problem. The steam engine developed by James Watt during these years provided the solution. Watt's steam engine remained basically unchanged for the next century and its uses expanded to change the whole nature of industry and transportation. 1885-1950 Coal was the most important fuel. One half ton of coal produced as much energy as 2 tons of wood and at half the cost. But it was hard to stay clean in houses heated with coal. Late 1860's The steel industry gave coal a big boost. 1982 Coal accounted for more than half of the supply of electricity but little was used in homes. In terms of national electricity generation, hydropower, natural gas, and nuclear energy
GLOBAL WARMING Global warming is the observed century-scale rise in the average temperature of Earth's climate system. Since 1971, 90% of the increased energy has been stored in the oceans, mostly in the 0 to 700m region. Despite the oceans' dominant role in energy storage, the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth's surface. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980
