A few things about Hughesnet that you need to understand... The $55 is the price for the connection, taxes and fees are not included, nor is the modem lease fee. Buying your own equipment is generally not a good idea, it costs a fortune, and if it ever fails, your out even more money. You are better paying the $10 monthly lease fee.
Plants use carbon dioxide and sunlight to create energy in a process called photosynthesis. As a byproduct of photosynthesis, oxygen is released. Most of the oxygen from photosynthesis comes from the ocean. Some bacteria, known as cyanobacteria or blue-green algae, also create oxygen through photosynthesis.
Photosynthesis from plants use carbon dioxide, sunlight, and water and a byproduct is oxygen. Before humans existed, the earth existed for millions of years creating an enormous supply of oxygen. Organisms and plants created a balance of oxygen and CO2. The Earth's net supply of oxygen comes from phytoplankton. Plants produce oxygen but use up what they make by producing carbon dioxide at night and when they are burned or decompose, so you see, the only thing that keeps us breathing is the tiny phytoplankton in the sea.
