You can have too much of a good thing. This is what seems to be happening in the earth’s atmosphere. Greenhouse gases surround the earth, and trap heat inside. They control the amount of heat coming in and going out of the earth’s atmosphere. Without greenhouse gases, the earth’s surface would be approximately -40C. (Williams, 1996) The gases make sure that the temperature is correct for sustaining life. But recently, there have been too many greenhouse gases released into the air due to human activity. The burning of fossil fuels, landfill sites and animal waste all release greenhouse gases into the atmosphere, especially carbon dioxide. If there are too many greenhouse gases, more heat gets trapped inside the earth’s atmosphere. This causes …show more content…

Photovoltaic cells, which can be found in solar panels, convert sunlight into solar power. However they only work when the weather and time is right, making it a temporary source of energy. Artificial photosynthesis would be able to store fuel, making it available even whatever the conditions. Artificial photosynthesis also has the ability to produce more than one type of fuel. The photosynthetic procedure can be altered to make the reaction between CO2, H2O and light produce liquid hydrogen. Liquid hydrogen can be used in hydrogen-powered systems as a gasoline. Hydrogen fuel cells can also produce electricity, which could be used to power a lot of everyday things. The main reason why artificial photosynthesis would be so useful is because it creates fuel from natural resources, so it doesn’t harm the environment. When humans burn fossil fuels, we emit toxic gases into the atmosphere that harm earth and increase global warming. Artificial photosynthesis emits oxygen, and doesn’t harm the earth at all. It is also a lot more sustainable as it uses Carbon dioxide, hydrogen and light energy to create fuel. These are all sustainable resources, unlike certain fossil fuels and oil, which are finite

Greenhouse gases are those that absorb and emit infrared radiation in the atmosphere. The most abundant greenhouse gases in Earth 's atmosphere are: Carbon dioxide, Methane, Nitrous oxide ,Ozone ,Chlorofluorocarbons (CFCs). Human activities also contribute to climate change by the amounts of greenhouse gases, aerosols (small particles). The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas in the atmosphere.

Although, it is required that we give it that push to do so. In a way, we are killing ourselves and many other forms of life on earth. We do this by simply driving our cars to work everyday, powering our factories, and in general emitting large amounts of CO2 into our atmosphere. When we begin doing this, the greenhouse effect goes from sustaining our lives to putting it in danger. Some of the hottest years in recorded history have occurred during the 21st century.

Looking at the difference of ethanol fuel and gasoline, the benefits of ethanol fuel by far outweigh gasoline. With ethanol fuel being made from biomass the amount of greenhouse gas emissions is greatly reduced from those of gasoline emissions. This is allowed to happen because when ethanol fuel is burned, it is burned in almost complete combustion making the emissions much more clear and less harmful to the environment. With a reduction of greenhouse gas emissions the benefits to the environment are huge. Our economy would be allowed to spend less money on environmental factors and more for the people.

‘Wow spectacular yet it's grieving, so many souls rising up from the Earth to the cosmos. Nevertheless the spiral cone shape likes a trumpet with the bell part gradually fade out horizontally to nowhere, is that part extended to the other dimension?’ His Dad says: ‘yes while in the human's dimension they couldn't see the spiral cone and us, whereas in this dimension you can't see beyond the trumpet bell.’ Bing continues: ‘I can't see clearly, are there many souls orbit around the bell shape? They formed a vertical donut shape to hover counterclockwise around the trumpet bell shape slowly, each of them orbits clockwise around the rim of the donut from inside out continuously.

“Nuclear power will help provide the electricity that our growing economy needs without increasing emissions. This is truly an environmentally responsible source of energy.” Michael Burgess Prior to the introduction of nuclear energy, fossil fuel was thought to be the only available source in producing energy. Although fossil fuel, such as coal, petroleum, and natural gas, contains high energy value, it produces too many harmful byproducts that ultimately pollute our environment. With the rising concerns over global warming as more and more greenhouse gases accumulate in our Earth’s atmosphere, many voice such opinions that new alternative, yet sustainable method must be adopted to produce energy.

When all these extra gases are released, carbon dioxide stars to accumulate in the atmosphere. Climate change is a global issue because when the temperature of the Earth changes even very slightly, it can cause droughts and our crops can die. This is affecting our food supply. Also, when water levels rise even slightly, it can be very destructive for

By releasing this gas into the air the natural greenhouse gases increase and cause many effects to happen. Carbon dioxide is also caused by removing natural resources from the land for agriculture. When the Earth starts to warm many other things do to, the ocean will become more acidic and glaciers might partially melt. If the oceans become acidic, fish and other sea creatures will have an unlivable environment. If glaciers start to melt arctic animals that rely on the ice may start to become extinct.

All of the greenhouse gases contribute to the atmosphere trapping heat and warming the earth and warming the Earth has many effects. The earth being warmed, meaning from North Pole to South Pole, melts ice in the poles. The melting of the ice causes sea levels to rise and the effect of that is flooding and lost habitat for animals. Increase in temperature makes some of population of plant and animal species go down. Increase in temperature also affects the weather.

Burning fossil fuels is one of the main culprits that causes climate change because it releases gases into the atmosphere that trap in heat and create the greenhouse effect. According to Klaus S. Lackner, the director of the Center for Negative Carbon Emissions and a professor in School of Sustainable Engineering at Arizona State University,”Dumping carbon dioxide and other greenhouses gases into the air raises their concentrations in the atmosphere and causes gradual warming.” This gradual warming is causing many horrific effects

These gases retain heat on earth thus increasing the temperature above average. Different gases have dissimilar abilities to trap heat. Deforestation is also another important reason for global warming. Plants release oxygen and take in carbon, thus providing us a clean and healthy environment. But by deforesting the lands, the trees would emit the carbon stored in them from hundreds of years making the air impure.
