Global Warming Awareness.

Global warming occurs when the earth heats up or the temperature rises.  It happens when greenhouse gases like carbon dioxide, water vapor, nitrous oxide, and methane  trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.  This hurts many people, animals, and plants.  Many cannot take the change, so they die.

Greenhouse gasses are gasses are in the earth’s atmosphere that collect heat and light from the sun.  With too many greenhouse gasses in the air, the earth’s atmosphere will trap too much heat and the earth will get too hot.  As a result people, animals, and plants would die because the heat would be too strong. 

Many things cause globalwarming.  One thing that causes global warming is electrical pollution.  Electricity causes pollution in many ways, some worse than others.  In most cases, fossil fuels are burned to create electricity.  Fossil fuels are made of dead plants and animals.  Some examples of fossil fuels are oil and petroleum.  Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned.  Some of these chemicals are called greenhouse gasses.

Global warming is affecting many parts of the world.  Global warming makes the sea rise, and when the sea rises, the water covers many low land islands.  This is a big problem for many of the plants, animals, and people on islands.  The water covers the plants and causes some of them to die.  When they die, the animals lose a source of food, along with their habitat.  Although animals have a better ability to adapt to what happens than plants do, they may die also.  When the plants and animals die, people lose two sources of food, plant food and animal food. They may also lose their homes.  As a result, they would also have to leave the area or die.  This would be called a break in the food chain, or a chain reaction, one thing happening that leads to another and so on.

One thing that is happening is warm water, caused from global warming, is harming and killing algae in the ocean. Algae is a producer that you can see floating on the top of the water.This floating green algae is food to many consumers in the ocean.One kind of a consumer is small fish.  There are many others like crabs, some whales, and many other animals.  Fewer algae is a problem because there is less food for us and many animals in the sea.

Marine algae capture huge amounts of carbon dioxide from the atmosphere,and when they die they would take the carbon stores to the bottom with them.

Global warming is doing many things to people as well as animals and plants.  It is killing algae, but it is also destroying many huge forests.  The pollution that causes global warming is linked to acid rain.  Acid rain gradually destroys almost everything it touches.  Global warming is also causing many more fires that wipe out whole forests.  This happens because global warming can make the earth very hot.  In forests, some plants and trees leaves can be so dry that they catch on fire.

We use these sources of energy much more than the sources that give off less pollution.  Petroleum, one of the sources of energy, is used a lot.  It is used for transportation, making electricity, and making many other things.  Although this source of energy gives off a lot of pollution, it is used for 38% of the United States’ energy.
