This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals also cause acid rain, that destroyes plants, rivers, lakes and buildings. Acid rain can travel thousands of miles, so pollution in one country can become acid rain for another country. So how to avoid the worst? Lets talk about cars, which are the main means of transport in our everyday life, they are useful and take us to the place, where we want to go. But lets be honest, they have also negative aspects. Like heavy traffic in the morning, while you are going to work and in the evening, when you are about to go home. Cars also, like factories, produce poisoned gas in the air. So instead of cars, we should use public transport or a bike, in the name of our enviroment. And what about the factories? Well, we can't remove them from the planet, but they should be built in places, where is less forest and no cities near.
ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution
better to blame others than to confront the truth of our being responsible for whatever has happened to us as an African race. I decided to write ‘Capitalist Nigger’ to open a debate on the state of the African race. But in doing so, my intention was not to treat my own contribution to the debate with kid gloves. It is to tell it like it is, the truth and nothing but the truth. My observations are bound to infuriate a lot of my people. Even the title of the title of the book is bound to make a lot of people angry. Many people will be angry, to say it mildly, when I question the intelligence of my people compared to the Asians (Indians, Pakistanis, Malaysians, Filipinos) and others who attained independence at the same time as most African countries. If the book generates the kind of dialogue, debate or argument for or against the position I have taken, so be it. But it would even be more relevant if in the process, solutions are offered to help
The list might be smaller than it once was, but there are some traits of ours that no other creature on Earth can match. No animal can get close to the devastation humans can cause (Credit: Thinkstock) No animal can get close to the devastation humans can cause (Credit: Thinkstock) Ever since we learned to write, we have documented how special we are. The philosopher Aristotle marked out our differences over 2,000 years ago. We are "rational animals" pursuing knowledge for its own sake. We live by art and reasoning, he wrote. Much of what he said stills stands. Yes, we see the roots of many behaviours once considered uniquely human in our closest relatives, chimpanzees and bonobos. But we are the only ones who peer into their world and write books about it. We see the roots of many behaviours once considered uniquely human in our closest relatives "Obviously we have similarities. We have similarities with everything else in nature; it would be astonishing if we didn't
The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today. As the world has industrialized and its population has grown, the problem of water pollution has intensified. The simple fact that millions of people live along coastlines and near rivers means that these bodies of water are likely candidates for heavy and destructive pollution. It is hard to know now what our oceans will look like in the future. Just how damaged they will be by pollution is uncertain. Acid rain The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results.
9, I was a phenomenal reader of books, a habit that persisted all the way until college. Reading expands one's mind immensely. It fires the imagination, demonstrates grammar, teaches vocabulary, informs, challenges, helps one relax. In some cases it forces the mind to concentrate, as to understand. It can help build a moral or ethical framework, and help oneself form an individual worldview. Even an untraveled child, sitting at home, can be transported by a book into any place or time. Fantasy and facts weave together, but the result is almost an unmitigated improvement. If a bookworm grows up to be antisocial or worse, it is not because of too much reading, but because something else was lacking in the education or caregiving. Hands-on learning is another factor difficult to overrate. Imagine trying to learn to draw from listening to a lecture. You must draw, draw, draw, and with time and tutoring, will improve

choose, a luxury that wasn't possible 100 years ago. Keeping our homes comfortable uses a lot of energy. Over 40 percent of the average home's energy consumption is used for heating. Another 20 percent is used for water heating, 8 percent for cooling rooms, and 5 percent for refrigeration. Almost one-fourth of the energy used in homes is used for lighting and appliances. Lighting is essential to a modern society. Lights have revolutionized the way we live, work, and play. Picture 2.2. How energy is used in homes (2005) 5 Most homes still use the traditional incandescent bulbs invented by Thomas Edison. These bulbs convert only about ten percent of the electricity they use to produce light, the other 90 percent is converted into heat. In 1879, the average bulb produced only 14 lumens per watt, compared to about 17 lumens per watt today. By adding halogen gases, the efficiency
