Answer 1

1) healthy diet leads to healthy living
Good morning to my respected teachers and all my fellow classmates. As we have gathered here to celebrate this auspicious occasion, I would like to speech over health is wealth. As we all know about the common saying that health is wealth but I do not think that we follow this proverb in our daily life to get maintained. Everyone of us knows well that a good health lead to the good way however no one of us take care of the health. If we are not living in discipline and following nature’s rule, we can never become healthy in the life and never reach to the success.
We have given two legs and two hands to walk and do work however if we are not using our organs accordingly in proper way, it is our fault which lead us towards failure. Most of the people spend their whole day and night just by sitting or lying on bed for most of the days of week and months. They are just like fish without swimming and birds without fly. Can you imagine that what will happen if fishes do not swim or birds do not fly, most commonly they easily would be food of big animals and slowly their species would get destroyed. In this way, people having more comfort in their life cannot be so healthy.

Global Warming occurs as a result of increased concentration of greenhouse gases in the atmosphere. The main greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide and ozone. These gases do now allow all the radiations from the Earth to escape back info space. This is known as the Greenhouse Effect. This trapped radiation or heat helps to keep the Earth at a constant temperature. Greenhouse effect is thus very important to main the temperature of the Earth at a habitable level. Over the past few 100 years, human have been burning trees and fissile fuels, thereby releasing millions of tones of carbon dioxide into the atmosphere. The increased level of carbon dioxide in the atmosphere has caused the temperature of the Earth to rise. This, in turn, causes more water to evaporate into the atmosphere. Water vapor is also very good at absorbing heat. This cause the Earth’s atmosphere to become even warmer. Scientist has called this effect ‘Global Warming’. They have warned that Global Warming could shift rainfall patterns, raise the sea level and alter the ecological balance.
