Another way of collecting heat from the sun utilizes flat plate collectors. “Flat plate collector is an absorber plate, a plastic plate, an array of pipes and insulation are the basic components of a flat plate collector. The absorber plate is basically a plate of black-coated metal used to trap the solar radiation and turn it into heat. A transparent plate is put on the top to contain the heat inside. Then pipes are placed between the plates with cold water passing through them. Then the heat is used for heating" ("Wind, Water, Sun, or Coal"). If focusing collectors and flat plate collectors are used retrieve heat, then how can water be produced with solar energy? Solar distillation can be used to collect water from rooftops of buildings.

Focusing collector has three components: heliostats, parabolic collector, and receiver. "Heliostats are moveable mirrors used to track the sun for the greatest efficiency. A parabolic collector collects and reflects the solar energy from the heliostats to a single point. And a receiver uses the concentrated solar energy at that single point. Focusing collector can provide a temperature as high as 4000 degrees Celsius” ("Wind, Water, Solar, or Coal").

Both natural disasters and human activities can cause carbon dioxide. Natural disasters like "volcanic eruptions will release about 145 million tons of CO2 into the atmosphere every year. If carbon dioxide level gets too high in an area, then it can be lethal to humans or any organic life around it. But compared to human activities, society emits about 24 billion tons of carbon dioxide each year that is like adding 17,000 more volcanoes to the ones we have now" ("Volcanic Gases Are the Driving Force of Eruptions"). Some human activities are burning of fossil fuel, deforestation, and some agriculture and industrial practices. “Burning of fossil fuel to produce energy for everything also produces about eighty-percent of carbon dioxide in the atmosphere. Agriculture also contributes to carbon dioxide emissions. Vegetation also emits carbon dioxide into the air but only accounts for about fifteen-percent" ("What Human Activities Contribute to Climate Change?"). Deforestation can also increase the carbon dioxide level because trees use carbon dioxide as fuel. To reduce deforestation effects, just simply replant trees somewhere close to the area of deforestation.

What can the people of this planet really do to save this beautiful home? If fossil fuel, agriculture, and deforestation are really affecting the planet, then should people eliminate fossil fuel from their lives? Are there any alternatives to power people’s houses, cars, and etc? The truth is there are some alternatives to getting power, but the problem is the cost of building these alternatives.

Not only will global warming have a large impact on humans, but also on wildlife and plant life as well. Many animals will seize to exist in the future. "Many animals are adapted to their natural surroundings, but if there is a change, they could be greatly harmed. Due to wetland disappearances, seal levels rise, and many animals that live there will die. Inlets, where the river meets the sea, will widen out, and cause the sea water to flow into rivers and streams. This will kill many freshwater animals. Trout and salmon depend on cold water to live. If the water were to warm up by only three degrees, trout could be threatened with extinction, and salmon would become endangered" ("Causes of Endangerment"). Once the amount of fish starts to decrease, then birds that depend on those fish will also start to die out. What really causes irregular weather patterns and extinction of animals? The primary cause is the emission of carbon dioxide into the atmosphere.

The movement of wind produces wind energy. "Unstable heating of the earth by the sun causes differences in air pressure and produces wind. Usually wind turbines are used to capture wind and turn it
