on how many of each species can be caught by each country in each year‚ so that fish stocks stay at viable levels - something the European Union is now trying to do. Energy:Sustainability in energy means replacing non-renewable energy sources (fossil fuels) with renewable sources such as solar‚ water and wind generation. Economic development:A sustainable approach must be able to improve people’s standards of living - particularly in the developing world - while actually reducing carbon dioxide

and lighting. The largest sources of energy in the world are oil (34%)‚ coal (26.5%)‚ and gas (20.9%)1‚ adding up to over 80% of global energy. These types of fuels are called fossil fuels because they are found in fossil carbon deposits in the ground. An important difference between fossil fuels and other sources of energy is that fossil fuels are non-renewable‚ meaning that once they are used‚ they are gone and cannot be replenished. Other common sources of energy are nuclear‚ hydro‚ and solid biomass

Many argues that Nuclear Power is a near perfect substituted in the place of burning fossil fuels because Nuclear Power does not create nearly as much Carbon dioxide‚ while others argues that the government have no actual plan for Nuclear Power Plant‚ and even if they did‚ the Nuclear Power Plant would be a massive target for terrorist attack

greenhouse gases are destroying layers of the earth’s ozone or atmosphere‚ which is the result of burning fossil fuels such as coal‚ natural gas‚ oil. Research done by Mann and other climate scientific points out that there is a serious threat to our planet as a result of the overuse of fossil fuels and the sharply rising levels of the gases as we continue to burn more and more fossil fuels. According to Michael Mann‚ he and other scientist over the past decades have become the victims of

Smog in 1952 that caused 4000 deaths and a host of other related ailments among the Londoners. One of the main causes of the serious air pollution was the burning of fossil fuels by the many manufacturing industries producing iron and steel‚ automobiles‚ machinery‚ textiles and food. Coal and Oil were the main sources of fuel for the factories which resulted in the release of carbon dioxide‚ sulphur dioxide‚ smoke‚ soot and other particulates. Inefficient machinery and obsolete techniques coupled

First‚ burning fossil fuels are burned‚ that is part of everyday in California and the rest of the planet and this is the major source of air pollution. The main fossil fuels burned by humans are petroleum or oil‚ natural gas and coal. Most of the demands on activities of the world-wide energy demand are supplied by the fossil fuels coal‚ oil or gas for example to drive a car‚ manufacturing and generating electricity. Consequently

Non renewable sources Are used in thermal power stations to produce heat energy that turns water into steam. The steam drives turbines and in turn drives the generators that produce electrical energy.

This is called “non-renewable” energy resources. Non-renewable energy resources consist of fossil fuels (petroleum‚ coal‚ natural gas) and uranium (nuclear energy). The amount of pollution released from producing energy is a big concern‚ but not all of the energy resources emit the same amount of pollution. The alarming fact is‚ recently‚ many of

evidence available to support and refute current claims of imminent threats to life on our planet and a need to actively respond now. Global Warming is an imminent occurrence that society faces on a daily basis; the effects of an increasing number of fossil fuels means that there is an increasing amount of CO2 being emitted compared to O2 which is slowly affecting the air not only humans but plants and animals breath on Earth. The greenhouse effect is a natural process that warms the Earth’s surface. When
