Example of Speech on Scientific Topic

 Good morning friends! How are you doing? (Audience: Fine). Please imagine a situation where there is a massive fire around you and the surrounding is filled with poisonous gases. It is hard to go outside because of suffocation. Yes, all of us will be burnt alive and embrace

death. This is the situation of nuclear explosion. Today, I, Reena, stand before you to speak on the disastrous effects of nuclear weapons.

Nuclear weapons have been the strongest and most destructive weapons created so far. These are so lethal that even a single nuclear weapon can destroy a whole city as well as jeopardize the natural environment and lives of future generations through its catastrophic effects. Every country has been influenced by their capacity of mass destruction and desires to add them to its arsenal. It is argued that these weapons bring power to the nations that possess them. The nations have been taken as extremely powerful and dominant because of

the power of these weapons. Since only a limited number of nations possess the ability to develop nuclear weapons, they strengthen themselves at the top of the global hierarchy. We can take the example of two super powers- Russia and the United States. They alone carry more than nine-thousand warheads which is eighty per cent of the entire number of such weapons all over the world. Many of these have been deployed on missiles, battleships, submarines and other deadly carriers.

The world realized their potential for the first time in 1945 when nuclear bombs were dropped on Hiroshima and Nagasaki during the World War II. People got only a glimpse of the destructive power of nuclear weapons; the bombing ruined the two cities completely as well as affected the whole country of Japan. It destroyed everything, leaving behind only a desolate landscape. The disastrous consequences of this bombing have been visible in the later generations. With the passing of time, these deadly weapons have grown more advanced and lethal. They can do much harm as compared to the old ones.

Many world leaders claim that nuclear weapons are vital to maintain a healthy balance of power and check the outbreak of war, but this argument is not acceptable. A country with nuclear capability threatens the other countries and keeps them under its thumb. The country can use its nuclear weapon in case of war. We have witnessed so during World War II. In spite of the insistence of global leaders that nuclear weapons prevent war and turmoil, these are a potential threat to mankind.

Now, a number of countries have developed nuclear weapons and can use them at any time to take revenge. They can end the world within hours. It is necessary to destroy all the nuclear weapons from this Earth for a bright future ahead.

Friends, I conclude my speech with these words. I hope you will understand the disastrous effects of nuclear weapons on mankind and become a part of the movement against these weapons. I thank all of you for patient listening. Thank you!
