An animal or plant
species that no longer exists anywhere on earth is considered extinct and
cannot be replaced. Numerous living organisms are at risk of extinction due to
their low population numbers, making them endangered without special
protection. The endangerment of a species eventually leads to their extinction,
as exemplified by the Bengal tiger, mountain gorilla, and panda, among others.
In Pakistan, species such as the wooly flying squirrel, snow leopard, and falcon
are currently endangered.
Wildlife refers to the
variety of living organisms in their natural habitats. Over the years, wildlife
populations have decreased significantly due to human activities, such as
deforestation for new roads, farms, and cities, as well as the use of
pesticides. Environmental pollution has reached an alarming level in some
countries, necessitating the implementation of bioremediation techniques to
remove toxic materials using living organisms. Algae, for example, have been
found to be effective in reducing pollution from heavy metals.
Pakistan is
experiencing significant environmental challenges, such as the threat to
aquatic life from sewage and industrial waste, particularly affecting fish
populations. Noise pollution is also a problem in major cities like Karachi,
Lahore, and Peshawar, while tannery industries have adversely affected the city
of Kasur. The exhaust emissions from vehicles are adding lead to the
atmosphere.
Protecting the earth's
natural resources and using them prudently is known as conservation, which is
essential for ensuring a sustainable future for the environment.
