Is Earth really being Harmed by Human Activity? In my opinion‚ the Earth is definitely being harmed or should I say damaged by human activity. It is quite obvious when we look around us‚ when we see read and watch the news‚ and when we research for ourselves. I believe the major cause in the damage of the Earth all began with the introduction of industrialization. As a result of industrialization‚ pollution came about. Deforestation was inevitable because of the expansion of urban developments

Then the being that was inside named Atlas came out and headed towards earth since he was near the planets. Atlas then started pulling things out a small bag that he contained around his waist. He pulled out things that looked like little mountains. Atlas then threw the mini mountains to the floor and Poof Mountains

Climate change will be the end of this world as we know it‚ according to David Wallace-Wells‚ the author of “The Uninhabitable Earth‚” an article which has spread through this country in something of a frenzy. Wallace-Wells’ article is fast-paced with alarmist tactics to target readers who believe they are in sync with the dangers of climate change‚ or those who may be on the fence about whether there is enough evidence to support the prevention movement. Wallace-Wells grows his credibility with

The temperature of Earth’s atmosphere is regulated by a process in which the quantity of energy Earth gets from the Sun is poised by the amount returned back into space. Greenhouse gases in atmosphere let the energy in and prevent it from escaping‚ directing it back to Earth’s surface . By

Antarctica has six months of daylight and six months of darkness. The earth revolves around the sun and tilts on its axis. During the winter‚ Antarctica is tilted away from the sun‚ causing it to be dark. For the half of the year that is summer‚ Antarctica is facing the sun and getting more of its direct rays. The lowest temperature ever recorded in Antarctica was -129degrees f. The warmest temperature ever recorded in Antarctica was 59degreesF. The average summer temperature is 20ºF. The average

The Biogeochemical cycles of Earth Earth with its many species and abundant live is a Biosphere in flux. As time passes with the seasons‚ the earth turning upon it’s axis and the movement of the sun’s rays North to South‚ makes it a place of movement and cycles. There are four cycles that are considered the four major biogeochemical cycles. The hydrologic‚ this is the transport of water around the globe. The nitrogen cycle‚ this is the movement of nitrogen within the biosphere. The carbon

Through the years humans have evolved beyond our expectations‚ while this is exciting we have caused damage and deterioration to our environment. From the air we breathe to the water we drink and the animals we consume‚ the environment is constantly being affected. First the very stuff we breathe
