While many skeptics insist that it is a myth, global warming is an increasingly important matter that world leaders should always seek to address. As nations become more industrialized and consequently more abusive of the environment, the temperature of the Earth continues to rise. As the most able beings on the planet (and the beings who are most responsible for global warming!), humans should attempt to reverse the downward trend before the damage to the earth becomes irreversible. However, before creating any policies to reduce global warming, leaders should take into consideration the cost of implementation and the global impact of such a great enterprise, as well as the environmental consequences. excellent introductory paragraph!

What prevents many nations’ governments from pledging to reduce waste to help the environment is the cost ly manner of such policies. The United States alone plans on spending “$8 trillion or 2% of the World’s GDP” on “stabilizing global warming” (E). The expenditure is incredibly high because every inefficient part ( ﻿part of what?) must be replaced to reduce the overall waste. In addition to purchasing new materials, the government must also remove and dispose of old equipment. ( not necessarily...) ﻿ Power plants, which are the sources of the some of the largest greenhouse gas output, require new, costly machinery. However, this high cost can be shared by the people. The United States has one the cheapest energy expenses in the world, meaning it costs much less to use electricity. There currently is a minimal tax on energy, and none on carbon, since it is not considered a pollutant. Citizens waste energy, because it is cheap. Leaders must put a higher tax on energy and perhaps one on carbon. The people “invariably choose to prioritize”, and higher taxes on energy usage would reduce waste, since citizens value their money more than their leisure (D). The taxes would help curb waste as well as generat e ing revenue from an untapped area. The cost of implementing these measures is the most determining factor, as leaders must always consider their economic limitations when enacting a policy. Strong closing, but perhaps mention at least one more possibly mean of receiving funds?

As all nations share one planet, environmental concerns are a global issue. Countries should consider the impact their decision has on a wider scale. The Kyoto Protocol is a pact formed between countries to “reduce their greenhouse-gas emissions” (A). Both the United States and Australia, “which together account for one-quarter of the world’s greenhouse-gas emissions”, did not sign the treaty, because of personal constraints (A). By declining to join, the United States, as one of the world’s largest producers, indirectly (not so indirect) harms the rest of the world and undermines the efforts of the other countries. Others worry that by spending so much money on environmental issues, nations are side-stepping their moral obligations to ensure that “the Third World develops as rapidly as possible” as well as to “ alleviate alleviating current global human suffering” (E). However, the window of time the world has left to fix its mistakes is closing. The greenhouse-gases trap light (be more specific, it's not just any kind of light--misleading) in the atmosphere and heat the earth, which creates devastating changes in the climate. Protecting “future generations” takes priority over any moral qualms simply because the state of the planet is urgent and more in danger. Great concluding sentence.

Environmental concerns are much of the reason why global warming is so alarming. From just this sentence, it seems as though this paragraph is going to discuss the exact same thing the last paragraph did--environmental concerns. The slight yearly increase in temperature causes changes in all aspects of life on earth. While there have always been slight fluctuations in the temperature of the ocean, plotting the temperature shows the dramatic increase over time (C). With the increasing oceanic temperatures, the polar ice caps are melting, sending vast amounts of water into the oceans and seas. The sea-level could rise by 3-5 meters, submerging all of southern Florida and disrupting ecosystems. (by when?) Glaciers on high mountains are in risk of melting as well. If they disappear, humans lose their major source of fresh water. There is a “tearing apart of communities” in the animal kingdom as well, due to the slightly change in seasons. The “global environment is changing so fast that the slow evolutionary process of species adaption can’t keep up” (F). Spring has appeared “nearly 10 days” earlier than usual, crowding out birds and wiping out flower species in “spring snowstorms” (F). Humans, plants, and animals are all greatly affected by the changes caused by global warming. Species are dying out, unable to survive the consequences of the damage done to the earth. This paragraph had lots of excellent facts, but not much analysis about what the significance of those facts is.

Few (eh) people are fully motivated to take action to prevent global warming because of the cost and time it takes to reduce waste. Certain governments are forced to bear the brunt of the cost and effort when it should be spread equally between the people and between countries. Despite political boundaries, all people are related in the fact that they all inhabit the same earth. Nature is sacred, and something as awe-inspiring as the diversity of life on earth should be preserved for the betterment of future generations. Strong closing!
