Threats of Biodiversity
“The loss of biological diversity is second only to nuclear warfare in its threat to human and other life on this planet.” - U.S. Environmental Protection Agency Biodiversity is the variability among living organisms from all sources, including inter alia [among other things], terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species and of ecosystems. Therefore, biodiversity is the connection among all living things on the planet, including their habitats and their interaction in the environment and all the living things on the planet.
But as ages and generations pass, biodiversity’s flow have had been disturbed. This is caused by the following elements:
* Constructing new roads due to the demand of urbanization. When urbanization takes place, it means there will be destruction of habitats among a lot of species. And to make the traveling means of urbanization convenient, C3 roads and shortcut roads are being built. As these roads are built, animals are displaced. Some of these animals may be in the care of animal rescuers; some found no habitat which caused for them to become injured or even die and be not able to reproduce anymore; and a lot are threatened by people and other animals and causes for them to become outnumbered. As an animal population grows or diminishes in one specific area, other species, plant life and even the soil are affected. When these factors are affected, biodiversity among animals and their environment is disturbed and vanishes little by little. * Population Growth. The earth’s total human population nowadays is reaching a number close to 9billion. Even with healthy ecosystems and crops growing at full capacity, earth can only sustain a limited number of people. As the population grows, so does the waste, as well as carbon footprint humans leave on planet. More people mean more wild land needs to be converted to farming land or residential properties, more pollution is created and more natural habitats are invaded. As people grow in number, cities are also widening to accommodate them. As cities are widening, natural spaces get smaller, affecting the animals and plants, and the interactions taking place between them in the environment. * Human Activities. Human activities also causes threats to the biodiversity. Activities like deforestation such as kaingin, cutting down immature trees, throwing garbage on parts of water, killing endangered animals on the forest for selling purposes, are just few examples of the hundred human activities. Most probably, this activities contributes a lot to the destruction not only of the biodiversity, but also of the planet where we live, the Earth. If human activities are done throughout the day everyday, probably, this world would suddenly collapse and life here on earth will be over. * Over-consumption or unsustainable use. Over-consumption is the harvest of species at a rate higher than what it can sustain through natural reproduction of the population. This means, we consume the products of the specie more than it could produce. In Ontario, for example, wild American ginseng has been over-harvested from its natural rich woodland habitat to the point of being endangered. * Having a car. Fossil fuel combustion is one of the most serious environmental pollutants in the world. Exhaust emissions, through smoke belching, are the primary cause of this, but pollution also comes from the evaporation of stored gasoline and other fuels. The less efficient a car is, the worse the problem becomes, because it consumes more gas and produces more emissions. Cars that aren't properly maintained can smoke or produce visible emissions. This smoke is caused by incomplete combustion, which releases toxic chlorofluorocarbons (CFCs) into the air. And the problems don't stop there....
