how does temperature, thermal energy and heat affect us in our daily lives (explain a postive and negative for each - if you are really good, you can use one example to explain the postive and negative of each)

Example of positive - sun gives heat such as thermal energy and thermal energy gives nutrients in plants and plants give foods to able for us to survive. 
Example of negative is - too much heat can lead into radiant energy and too much radiant energy can cause an explosion. also too much heat can cause you to a severe burn such a second degree burn. high temperature can lead to dehydration. 
Hope this helps
