5 issues that the world must be concern today.

electricity, it’s much cleaner and better than burning gas. Paper recycling, some discussion of renewable energy sources, support mass transit, electric sources of transportation, or choose other forms of transportation that do not harm the environment are also the solutions to fix this problem. DeforestationThe Earth was being striped of fifty-one million acres of tropical forest each year. Only forty percent of the original moist forests remain in tropical Africa and thirty-seven left in Asia. Certainly those statistics are riveting and extremely frightening! Eventually, at the current rate of deforestation, there will be no trees. The removal of all of the forestland affects the environment in extremely adverse ways. The amount of rainfall declines, thus many of the species that are adopted to the climate of the region will not be able to survive. They could become endangered, or even extinct. The soil can erode. This would add to the degradation process and make already poor soil, even less fertile. When the forests are removed and the rainfall begins to decrease, the water supply would suffer. The streams, surrounding lakes and rivers could experience sedimentation. The water that is used will not be replenished, eventually leading to the evaporation and drying of the water that remains. As a member of our society, I would not like to see the day that money hungry men cut down the last tree for their business. Deforestation would most likely not exist if we decrease our usage of paper. Nowadays, there is no need for paper other than for printing. In addition, if we just accept computers as a superior alternation to paper and use laptops instead of paper at school, perhaps, more trees would be planted rather than being chopped down. Global epidemics As the World becomes globalize, rapid travel can allow diseases to travel the world in a day and spread faster than ever. In addition, intensive agriculture and land development is bringing humans closer to animal pathogens. The recent appearance of the West Nile virus in New York is a good example and it has made the issue of global epidemics a concern for health officials. Even though new treatments have made other diseases less of threat but these diseases can be released to one person and spread to infect thousands or millions. They cause terror and death. Some are highly infectious, and can spread across a population with terrifying speed. Others can simply be posted to an enemy, as we saw during the anthrax attacks. Moreover, the next virus could be as deadly as AIDS or worse. And we are not ready for it. What we should do immediately is to increase the accuracy of the global surveillance system and also the disease detection. We must also treat our water carefully and protect people from disease-carrying insect. This is especially important because some of the deadly diseases that might be unleashed by terrorists, such as anthrax and smallpox, could at first be mistaken as an ordinary cold or flu.OverpopulationThe key to understanding overpopulation is not population density but the numbers of people in an area relative to its resources and the capacity of the environment to sustain human activities. To meet the demands of the growing population, we are clearing land for housing and agriculture, replacing diverse wild plants with just a few varieties of crops, transporting plants and animals, and introducing new chemicals into the environment. The number of people would keep increasing while the amount of available food would stay the same or even decline. Oil would soon be used up. The consequences might be something we'd never think of, until it's too late. In the late 1960s and early 1970s some environmentalists stated that the world’s ever increasing population, would soon outstrip the planet’s limited resources. Perhaps the powers that be have an interest in keeping you thinking we can expand forever, implying that the Earth's resources are limitless. Perhaps the capitalistic economic system that rules Earth does not want to let you know the truth about our crashing population and that we will reach zero population growth very shortly. The true reasons why our population is crashing is we have passed our sustainable limits for both of our major food energy sources, grains and fish, as well as very quickly reaching our fresh water limits. On the other hand this is bad because we have yet to recognize the alarming facts that for the last 16 years we have passed the sustainable food limits that Earth can produce relative to population. This plus our population is going down faster and faster each year for 13 straight years. Meanwhile 3.6 billion people are barely getting enough to eat with more than 1 billion of them in total abject poverty. And let us not forget that somewhere between 10 and 30 million children die every year of the worst possible death, starvation and starvation related diseases. The best way to solve this problem is from increasing educational opportunities and family planning resources for women who already have more than couple children. Besides, the problem of overpopulation would get much better if we adopt some strict policies to control population, such as China’s One Child Policy even though it somehow against the law of human right. TerrorismTerrorism is a growing international problem. During the last twenty years, new terrorist groups have sprung up all over the world. Most terrorists, unlike criminals, claim to be dedicated to higher causes, and do not believe in personal gain. They use terror to achieve their goals. The methods that they use include threats, bombings, and the destruction of property, kidnapping, the taking of hostages, executions, and assassinations. Today, terrorism poses a threat to innocent people, and is a serious threat to democratic forms of government. Terrorism in the past years has been politically motivated, in the future; it will be religiously motivated. This might cause a major problem in the future because each year more and more people create or advance a religion to suit their liking. For instance, the most recent attack on America has been on the WTC and pentagon. Thousands of innocent people died because the Al-Quaida allegedly flew 3 passenger aircraft into both towers and crashed one into the pentagon. War will have a new face; it will be attack miscellaneous targets in random locations invisibly. This is why if we don’t act quickly; the world could be cast into turmoil. It is impossible for us we to see an end to terrorism if we don’t learn how to make peace and establish justice, not by adopting the terrorist methods of the criminals, but by protecting everyone's rights, and also learn how to share our wealth rather than merely exploit people. We need a steady process of disarmament with very careful inspection so that no individual, group, or state can terrorize other people.ConclusionWe all are human beings first and as human beings the problems, humanity is facing today, are the sense of fear and insecurity. Human societies will always face significant challenges and problems to overcome the past. From the numerous amounts of ways to destroy this planet, humans might still not notice that there could be alternatives that can actually help this planet. Or even they do, they won’t do it. The major factor in the acceptance of these alternatives is the rate of acceptance for people. If we still continue to live like what we do and keep destroying the environment, it will also destroy us at the end.
