The population of people would run out of food
yes, i do. animals are a unique part of todays society. without animals we would not have gotten to the moon because animals were the first living things from earth into space.

if all the animals were gone there would be no carbon dioxide for plants and trees to take in and no oxygen would be produced.
without the sun plants would not be able to be produced which would lead to animals not having food, which leads to dinosaurs to have no food and die -hope it helped
Life wouldn't exist because animals need oxygen.
if people threaten for example "animals habitat", the animals would have nowhere to rest or even eat,some habitats are animals habitat and food so it is very important to not threaten a animals habitat etc. they would starve, it would be so boring without animals around wouldn't it be so?
The humane treatment of animals is what is practiced in shelters such as the Humane Society, so that they be healthy.
Many animals, including whales, would have problems adapting. Also, the oxygen produced by the photosynthesis of some plankton would have extremem affects on the atmosphere.

Because: 1. Oils come from the underground of the ocean 2.Oils are probably very poisonous to animals. 3.Oils cannot be produced by animals or anything else in the world.* *(Exception:Oils can be produced but it would probably about 10 million Years) SUPER LOL BY WEEE43 :P
Animals get calcuim by just eating what they do. For instance, if some animals eat plants, then there would be a chemical reaction between the plant and what the animals body makes the food into. So, basically, the animals bodies themselves can make calcium.
Carbon Dioxide is water soluble. Some of the main sources would be CO2 produced bay any animals that live in water and CO2 produced by decay of vegetable matter.
