Wars break out for various reasons. There are wars between countries or nations and within the nation. The latter is generally known as a civil war and can occur as a result of differences based on race, religion, socio-economic dissatisfaction among others. Whether wars are waged between countries (interstate) or inside the country between different sections of the communities, the effects are very damaging. According to experts, the main reasons or factors that contribute to wars are human greed for wealth and intolerance towards the other. Many world leaders in fact believe that the main reason America invaded Iraq was for its oil wealth. Hundreds of thousands of innocent Iraqi civilians as well as American and Iraqi soldiers have been killed, injured or maimed. During the eight-year war between Iran and Iraq in the 1980s, there were more than 1 million casualty figures with millions injured. The attack on the American World Trade Centre on 11 September 2001 killed close to three thousand people and the subsequent reprisal on Afghanistan by American forces killed thousands of people in that country. World War 1 and World 11 combined have claimed millions of lives and in the African continent, tribal wars and regional wars continue to occur. The civil war between the Hutus and Tutsis in Rwanda tad claimed more than 3 million lives and in the Democratic Republic of Congo, more than 3 million people have died due to conflict between warlords. Many countries especially in Africa are still embroiled in tragic wars. The effects of war are both physical and psychological. Human societies are deeply affected by wars as residential areas, public infrastructure, hospitals and the very basis of human existence are destroyed. Malaysia too experienced war when it was once occupied by the Japanese and people faced many hardships and challenges to meet their basis needs. The Japanese only surrendered when the unconventional weapons or better known as nuclear weapons were used on Hiroshima and Nagasaki which took thousands of lives and maimed as well crippled thousands of people exposed to radiation. Thankfully, most warring nations still use conventional weapons like grenades, rockets and otters which do not inflict that kind of damage as nuclear weapons. Wars bring untold miseries as well as political and economic instability. People's lives and daily existence come under threat. It would be difficult to find jobs or live our normal day-to-day existence. Populations are displaced and have to constantly move about for security. What is happening in Darfur, Sudan is a dire reflection of the tragedy wars bring. Some are scarred emotionally and physically for life. Thus, humans must avoid wars at all cost. The only way we can protect our lives and ensure stability in our country is to practice tolerance and respect for each otter. Or else, we too would become extinct like the dinosaurs!
