consumption‚ compared with roughly 85 percent from oil‚ natural gas‚ and coal. Those fossil fuels cannot remain the dominant sources of energy forever. Whatever the precise timetable for their depletion‚ oil and gas supplies will not keep up with growing energy demands. Coal is available in abundance‚ but its use exacerbates air and water pollution problems‚ and coal contributes even more substantially than the other fossil fuels to the buildup of carbon dioxide in the atmosphere. For a long-term‚ sustainable

It happens when greenhouse gases such as carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. Greenhouse gases are released mostly by the burning of fossil fuels for transportation‚ heating‚ electrical appliances and manufacturing‚ but they are also released as a result of the natural decomposition of organic materials‚ wildfires‚ deforestation‚ and land-clearing activities. The diffusion of these gases

The program replacing climate change initiatives‚ visualizes a country that taps into U.S fossil fuel supply‚ yet does not display any sort of view on the increasing climate change issues as well as mentions no such addresses to its solution” (Kahn).

Moreover‚ studies from the recent volcanic eruptions such as El Chichon‚ Mexico (1982)‚ and Mount Pinatubo‚ Philippines (1991) showed that the sulfuric acid liquid drops from these volcanoes also subsidize the depletion of our ozone layer (Volcanic gases and their effects‚ internet). On the other hand‚ even if human have not existed on earth‚ carbon dioxide emission would still happen. Over 95% of the world emission came from what we call the natural cycle of CO2

Tomorrow never comes because of climate change” Before I start lets define first what was climate change is. Climate change or also known as Global Warming‚ refers to the rise in average temperatures on earth. This is due to primarily human use of fossil fuels‚ which releases carbon dioxide and greenhouse gases into the atmosphere‚ which can have a range of effects on ecosystems‚ including rising sea levels‚ severe weather events‚ and droughts that render landscapes more susceptible to wildfires. Isn’t

Gases‚ other hydrocarbons such as coal‚ Plant kingdom etc. All of these play an important role in the life of the mankind. The replenishment of these is not possible. Increasing consumption and demand of these resources has embarked a danger of depletion of the reserves of such natural resources. Also‚ to maintain the ecological balance and avoid the earth from global threat of the reserves being exhausted‚ the need of this hour is to think and strive for the conservation of these natural resources

Over-extracting can also be of a waste as not all of the resource is used and so it won’t stay in tact for a long time. Fishing‚ irrigation and the combustion of fuels are few of the many reasons. Fossil fuels won’t last forever therefore we need to act sustainable and use less of them. None of the less‚ the combustion of fossil fuels is harmful to the environment as it emits a lot of gasses and carbon dioxide which are a cause to pollution and also global warming. Fish is also in danger to become
