Humans are so vain, they think they are more important than any other living thing on the planet. Nothing could be further from the truth. In fact, humans are the one life form that other life forms could do quite easily without.
The honeybee, in particular, is often regarded as one of the most important species on our Earth. They pollinate many plants, such as fruit trees. Now you might say “We can live without Apples.” and you would be mostly right, but can we live without alfalfa? Honeybees are the major pollinator of alfalfa, and many other animals depend on alfalfa to some extent. Even soy is pollinated by honeybees, so if we were to give up eating cattle (because there is no alfalfa for them to eat, and grass often does not offer enough protein) and think we can rely on soy to feed us, we need to think again. Many scientists warn that if honeybees go extinct, other species both plants, and animal (including humans) would die out shortly thereafter.
If grasses were to vanish surely most other animal life would die off very soon. While we can quite easily live without front lawns, grasses are so much more than that. Rice is a grass, so is corn. Many animals depend on some type of grass for their survival. Grasses are also critical in the production of oxygen, being one of the most common types of plant life on the planet.
Our oceans are filled with life, but much of this life is tiny, even microscopic. Phytoplankton is the tiny plant life that drifts around on the ocean taking energy from the sun and turning it into food for other animals, that is say, phytoplankton are eaten. They are a vital part of the ocean food chain. In the seas most life depends either directly, or indirectly on phytoplankton. Without it live in the oceans would come to a halt. Additionally because of their large numbers they are responsible for producing as much as half of the worlds oxygen.
Although we have come to fear bacteria they play a vital role in most species. Bacteria are in the digestive system of animals and are critical for digestion. In the environment bacteria play a role in decomposition, turning dead things into food for plants. Some would argue that bacteria are also important for keeping populations in check, as when populations grow there are increased risks from bacterial diseases. Man has tried to rid themselves of this risk only to face problems as the result of global human over population.
