How is the atmosphere is changing?
When you say atmosphere changing, i assume you are talking about global climate change. The rate at which the temperature is changing now is much faster than any other point in the Earth's lifetime. This is due to the emission of greenhouse gases, which trap in infrared radiation and heats the Earth.
You are completely right; I am going to do my best to think about the future of this planet before I liter or over use things that will cause more and more energy to be used. Maybe the best way for me to help out the environment is to save water by convincing my family to invest in giant buckets that catch and store the water.
