Here is your essay on Controlling Water Pollution
In the early Carboniferous, the but into the supercontinent called . The period from the to the late Permian about 260 mya is also called the , which had various stages of ice sheet development. It was the last ice age before the current ice age. About 325 mya, there was a , but others are doubtful, and the . It was caused by fluctuating sea levels due to the ice sheet advances and retreats and the continental uplift that resulted from the continents colliding to form Pangaea. The ended with that extinction and the began. That growing ice cap eventually destroyed the Carboniferous rainforest. Cooler oceans have less evaporation and therefore produce drier climates; that dynamic began reducing the Carboniferous rainforest, breaking them up into “patches” that kept shrinking, to eventually result in the rainforests' collapse. Only a few rainforest pockets survived into the Permian Period. As usual, scientists have , but climate change is probably the ultimate cause. The collapse of the rainforest ended the dominance of amphibians and flora and fauna adapted to warm, wet environments. The cooler, dryer conditions that ended the Carboniferous led to the dominance of and .

The USA’s Civil War was not only a watershed event in American history, but it also became a pivotal event in world history. It marked the transition from a largely rural nation, , to quickly becoming an industrial juggernaut that Earth had never before witnessed, with consequences both salubrious and catastrophic. The final chapters of the USA's imperial history have yet to be written. With the Civil War, the . What I call phase two of the Industrial Revolution began, and the rise of oil and electricity dramatically transformed industrial civilization.
Here is a brief summary of this essay. Ever since more than three billion years ago and about a billion years after the Sun and Earth formed, organisms have continually invented more effective methods to acquire, preserve, and use energy. after three billion years of evolution and, pound-for-pound, it used energy . The story of life on Earth has been one of , and in turn influencing them. During the eon of complex life that began more than 500 million years ago, there have been many brief for some fortunate species, soon followed by increased energy competition, a relatively stable struggle for energy, and then cleared biomes and set the stage for another golden age by organisms adapted to the new environments. Those newly dominant organisms were often marginal or unremarkable members of their ecosystems before the mass extinction. That pattern has characterized the journey of complex life over the past several hundred million years. among some animals, which provided them with a competitive advantage.

When investigating how ice ages begin and end, and feedbacks are considered. A positive feedback will accentuate a dynamic and a negative feedback will mute it. In the 1970s, and the author of today’s , , , which posits that Earth has provided feedbacks that maintain environmental . Under that hypothesis, environmental variables such as atmospheric and levels, levels, and Earth’s surface temperature have been kept relatively constant by a combination of geophysical, geochemical, and life processes, which have maintained Earth’s inhabitability. The homeostatic dynamics were mainly negative feedbacks. If positive feedbacks dominate, then “runaway” conditions happen. In astrophysics, are responsible for a wide range of phenomena. A runaway greenhouse effect may be responsible for . Climate scientists today are concerned that burning the hydrocarbons that fuel the industrial age . Mass extinctions are the result of Earth's becoming largely uninhabitable by the organisms existing during the extinction event. The ecosystems then collapse Mass extinction specialist recently proposed his as a direct challenge to the Gaia hypothesis.
Prevention and solutions to water pollution
This particular type of pollution is made of a diverse variety of harmful materials that when introduced into Earth's atmosphere, destroys the equilibrium of our living environment.

Since the most dramatic instances of speciation seem to have happened in the aftermath of mass extinctions, this essay will survey extinction first. A corollary to is that if any critical nutrient falls low enough, the nutrient deficiency will not only limit growth, but the organism will be stressed. If the nutrient level falls far enough, the organism will die. A human can generally survive between one and two months without food, ten days without water, and about three minutes without oxygen. For nearly all animals, all the food and water in the world are meaningless without oxygen. Some microbes can switch between aerobic respiration and fermentation, depending on the environment (which might be a very old talent), but complex life generally does not have that ability; nearly all aerobic complex life is oxygen dependent. The only exceptions are marine life which has adapted to . Birds can go where mammals cannot, , for instance, or being , due to their . If oxygen levels rise or fall very fast, many organisms will not be able to adapt, and will die.
