Humans And Other Animal Species
Over Fishing
over fishing one of the ways humans affects animals life.
digging for fossil fuel
What are fossil fuels ?
To What Extent Does Humans Affect Other Animals Species Life?
Introduction
Humans know a days are progressing is science and technology to make there life more better, but unfortunately it affects the environment and so the animals' life too.
There are different ways the humans affect animals life. One way is pollution, that affects the animals and caused many of them to die and/or extinct, things which causes pollution such as factoriese.The second way is destroying their habitats by different ways such as:-
1)deforestation
2)destroying lands to build factories
3)over fishing
4)digging underground for oil and fossils


To What Extent does humans affect other animal species?
Humans can affect animals life by deforestation.
Deforestation
what does the term deforestation mean? The terms deforestation means clearing forests for building factories,buildings,compounds and malls.
when deforestation takes place at any forests, they burn the trees and plants. This pollutes the atmosphere and this harms the animals and birds. when a forest gets deforested lots and lots of animals looses their life and their habitats. This leads to animals getting extinct.
Reefs are suffering directly and indirectly from the increasing pressure of mans' resource exploitation (Reef Education Network). Overfishing is one driving pressure that has had devastating impacts on coral reefs. Aggressive fishing methods have hurt coral reefs sometimes beyond repair. However, overfishing in general is also a damaging problem to many coral reefs around the world. Specifically to the Great Barrier Reef, overfishing has caused a shift in the reef ecosystem. Overfishing of certain species near coral reefs can easily affect the reef's ecological balance and biodiversity (Reef Education Network).
Destructive fishing techniques can direct physical impacts on reef environments or create a deceit of certain species in the ecosystem.
Unauthorized fishing occurs in areas that are not supposed to be fished causing even further destruction to coral reefs (Great Barrier Reef Marine Park Authority).
" Recreational fishing is also an important activity with about 56,000 privately registered boats fishing in the Great Barrier Reef region" (sustainable Fishing).
"The vulnerability of coral-reef species is partly because of their life-history adaptation to uncertainty in survival of recruits and juveniles in diverse communities where predation and competition are intense. with low rates of survival of recruits, multiple attempts at reproduction are favored through longevity and large size. These traits lead to low rates of population turnover and special vulnerability to overfishing affects multiplicities assemblage composition, food-web dynamics , or ecosystem function"
(Birkeland, Charles). Overfishing can devastate the marine ecology of the Great Barrier Reef because of the specific needs of the coral reef.
Since certain amounts of nutrients, oxygen and salt content the fishes in the coral reef ecosystem help maintain the balance needed by the corals, with out these fishes the coral reef will collapse (Coral Reef).
The Great Barrieer Reef Park has several methods to manage specific zones of fishing, the created the Australian Commonwealth law to protect critical areas. In 2003, 24% of coral reef habitats were included in " no-fishing zones"
which is about 4% of the total park area (Sustainable Fishing)
There are many necessary steps needed to help stop overfishing including, designing effective conservation programs, determining the impact of management actions, understanding the drivers of overfishing, and deciding how are made to exceed sustainable limitations on fishers (Great Barrier Reef Marine Park Authority).
Fossil fuels were formed millions of years ago when plants, animals and other creatures died and buried under the earth. Their remains gradually changed over the years due to heat and pressure in the earth’s crust and formed to coal, oil and gas. These are the 3 major forms of fossil fuels and were formed from the organic remains of plants and animals. Since, they took million of years to form, that’s why they are also called as non-renewable energy sources. This means that they cannot be used again once they are expired. Over several years, these decomposed plants and animals were converted into black rock substance called and coal and thick liquid called oil or petroleum, and natural gas
How digging for fossils affects animals?
There are some animals which lives underground like moles, these animals comes to loose their habitats (the place where they live) . Not only their habitats but their lives too, maybe before digging the animal didn't run away,the humans starts digging and the animal may get injured and die.
Destroying lands for building buildings and factories.
Now a days humans are getting more and populations every year gets multiplied. So governments thought of destroying lands like forests to build more cities and buildings for the people to live. this has an advantage for humans, unfortunately animals and our environment pays for that. By destroying these lands they destroy the habitats of the animals who lives in the forests. and when the animals don't have habitats they won't have a sours of food and no shelter , which means they will die in either ways , of hunger or danger (no shelter).
What did we do for these innocent creatures?
Our group thought of communicating with people from other societies by creating a facebook page. And fortunately people showed response.
