What is Biodiversity Why is Biodiversity important What is Ecosystem How did Biodiversity and Ecosystem loss originated What is its current status Solutions What will the issue look like in the future How does it affect us How does politics and culture affect this issue
Biodiversity is the variation of life forms that are in a an ecosystem, biome, entire planet. Biodiversity can measure how well the ecosystem is doing.
“Biological diversity, or biodiversity, refers to thevariety of life on Earth. As defined by the United Nations Convention on Biological Diversity, it includes diversity of ecosystems, species andgenes, and the ecological processes that support them.”
It helps the decomposition of dead plants and animals so it enrich soils, this is done by insects, worms, bacteria and other tiny organism. Animals: food supply, medicines, etc Plants: food, O2, Animals and plants gives us 30 percent of medicines we use.
It is a physical environment shared by a variety of living organisms (animals and plants). ¨Wetland ecosystems filter out toxins, clean the water, and control floods. Estuaries act as marine-life nurseries. Forest ecosystems supply fresh water, provide oxygen, control erosion, and remove carbon from the atmosphere.¨
Biodiversity and ecosystems loss originated over 200 million years ago. A specie could last between 2 and 10 million years, however, their extinction was due to natural causes rather than to human activities such as the case of dinosaurs and their family. Then through time the rate of loss increase.
“Over the past 100 years humans have increased the extinction rate by at least 100 times compared to the natural rate. The current extinction rate is much greater than the rate at which new species arise, resulting in a net loss of biodiversity.” It is difficult to determine the exact rate of loss because it is constantly increasing exponentially Scientists have stated that there is around 8.7 million species on earth nowadays
Recycle Don’t buy any souvenir that has a body part of an endangered animal. Promote awareness about this problem. Create protected areas and reserves Governments should support, encourage, and contribute with research studies that helps biodiversity. Help enforce environmentalist laws and treaties, is one of the solutions that would definitely help the most.
As population keeps increasing... We’ll have an increase in air and water pollution pollution (industrialization, greenhouse effect) Species such as the Polar bear and the Giant Panda could be gone as soon as 2012 Climate change will kill ecosystems vegetation and its biodiversity. Extinction of fish species due to over fishing.
Demand for food will increase, while supply will decrease. Food supplies are going to be more vulnerable to pests and infections. Some will die from starvation and other will get infectious diseases, such as what’s happening in Africa.
In some countries, where there’s a lack of property rights and regulations enforcement by the government, biodiversity loss and a degradation of our ecosystems have been increasing. Also, cultural aspects such as changing diets, population growth, religious worships, and urbanization make loss rates even higher because animals and plants are directly influenced by these changes and actions made by humanity
