Biomes in the temperature zone have been changed the most by human activity.
We can define biomes as the community or group of animals and plants that are distributed or categorized on the basis of common characteristics of environment they are in, five<span> major types of biomes are aquatic, desert, forest, grassland, and tundra.</span>
In some places, especially some new wells that have just been drilled,
the oil is under pressure, and it brings itself to the surface as soon as
you drill a 'pipe' for it to rise through.
In most oil wells, there's a pump bobbing up and down day and night,
pumping the oil up out of the well.
When the well is so old that even a pump isn't very effective, water is
often forced down the well under pressure, and the water forces the
oil back up through the pipe.
