Natural resources
Biology has different applications and interrelationships with Earth
Sciences. One of these applications is the study of natural resources; ecology
is the study of the ecosystems and the relationship between living organisms
and their environment. The meaning of natural resources is based on this; resources
provided by nature that humans can use for different aspects. The natural
resources are subdivided into two groups: renewable natural resources and
nonrenewable natural resources. The majority of the energetic resources need
the natural resources for their optimum performance; also other human use
depends on these resources of nature.
Renewable natural resources are that they renew their selves at a faster
rate or equal than the rate of consumption. These resources include perpetually
sustainable resources that never run out. There are many sustainable resources that
human beings utilize during their daily life and as resources that are
perpetually renewable. Solar energy, wind power, hydroelectricity, tidal power,
bio energy from biomasses and geothermal power are examples of renewable
resources. Each one of these generates electricity to the population; solar
energy are taken by photovoltaic cells, wind power is acquired by eolic
turbines, and hydroelectric takes advantage of the force of water that go
through a reservoir. Renewable resources are those that naturally replenish
themselves at as sustainable rate; some of these are oils from plants, natural
gasses, water, oxygen, alcohol. Renewal commodities are the items that are
depleted but can be carefully regulated and replaced to make them sustainable;
for example, meat from animals, fruit, vegetables, paper and ground water are
some of renewal commodities, necessary to humans.
On the other hand, we have the nonrenewable natural resources that
consist in the energy sources that we use and consume faster than nature
produces them. Resources like fossil fuels (that take centuries to form
naturally) and crude oil (that take millions of years to form) are not infinite
and will cease to exist. There are four principal nonrenewable energy sources:
oil and petroleum products, coal, natural gas and uranium. These natural
sources are formed from geological and evolutionary processes that take long
time to originate. Metals and minerals are also nonrenewable resources for
example: gold, copper, aluminum, silver, lithium, diamond; and once these
materials are mined, they cannot be replaced at a sustainable rate. All of
these have different uses and the people utilize it every day; gasoline, a petroleum
products, are used to move our cars, petroleum is also used to produce
electricity; many products like plastic come from derivate of petroleum; coal,
uranium and natural gas are used to produce energy; almost all products contain
at least one metal or mineral that takes years to occur again.
Overexploitation of natural resources can create many ecological and
social problems. The contamination of these resources also generates some
critical situations that produce damage to the environment and people. Moreover
the use and production of some nonrenewal sources such as petroleum and coils
generate large quantities of pollution to environment, specifically to air and
water. For this reason, using responsibly and carefully the renewal nature
resources is a great option to decrease the quantity of contaminants present in
the environment as they are clean energy sources. Also diminish the high
consume can reduce exploitation of all of these sources. Another great practice
to keep the natural resources is recycling, process whereby many products are
reused and it reduces the amount of trash that is sent to landfills. Each
person can make some activities like walking or driving less to reduce the fuel
and therefore diminish the pollution that is a menace to the natural resources,
the same that we use every day to survive. In this way, we can maintain the
environment clean and have a better performance from the natural resources.
