what are the effects of global warming?

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.  

The oceans are affected by global warming in other ways, as well.  Many things that are happening to the ocean are linked to global warming.  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.  (A producer is something that makes food for other animals through photosynthesis, like grass.)  This floating green algae is food to many consumers in the ocean.  (A consumer is something that eats the producers.)  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. 

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.
