The earth’s biodiversity is in grave danger. In the present era, human beings are the most dangerous cause of destruction of the earth’s biodiversity. In 2006, the terms threatened, endangered or rare were used to describe the status of many species.
Because of this, many experts are looking for a way to help stop the fast rate of extinction of thousands of species per year. It would help if all human beings do what they can so that biodiversity can be saved. Simple things can lead to greater answers and will eventually help dying species all over the world.
The sad truth about Habitat Destruction
Habitat destruction is a major cause for biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution and global warming. Species which are physically large and those living in forests or oceans are more affected by habitat reduction, some expert’s estimate that around 30% of all species on earth will be extinct by 2050. According to the International Union for Conservation of Nature (IUCN), globally about one third of all known species are threatened with extinction. Even it is estimated that 25% of all mammals will be extinct within 20 years.
Dangers of Climate Change
Due to combustion of fossil fuels, the concentration of carbon dioxide and other greenhouse gases in the atmosphere has been increasing alarmingly. All these gases have been present in the atmosphere to keep this planet warm for the existence of human life. Since last few decades and mostly due to industrial revolution, the presence of these gases in the atmosphere has accumulated steadily resulting in enhanced greenhouse effect.As a result, world’s average surface temperature has increased by around 0.6 degrees Celsius over last 100 years. The changing climate patterns have already made significant impact on our planet. Melting of polar ice caps, change in rainfall patterns, increase in frequency of hurricanes, storms are few of the adverse effects of climate change. Scientists predicted that due to on-going activities contributing to global warming, the average global temperature could increase between 1.4 and 6 degrees Celsius in the 21st century.
Overpopulation: an undesirable disease of the Earth
Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation. It is possible for a sparsely populated area to become densely populated if it is not able to sustain life.Growing advances in technology with each coming year has affected humanity in many ways. One of these has been the ability to save lives and create better medical treatment for all. A direct result of this has been increased lifespan and the growth of the population. In the past fifty or so years, the growth of population has boomed and has turned into overpopulation. In the history of our species, the birth and death rate have always been able to balance each and maintain a population growth rate that is sustainable.
It is better for people to know the causes of biodiversity loss first before looking for a solution in fighting it. Being able to understand can help in looking for a better way in helping the dying species and stop the top causes of this problem.
