been projected to exist (Becher‚ 1998‚ 60). Tropical entomologist Terry Erwin’s research supports that there may be as many as 30 million insect species alone in the tropical rainforests (Shiva et al‚ 1991‚ 14). One of the true challenges to biodiversity is that there are so many species that we may be obliterating that we are not even aware exist yet. We are destroying species faster than we can identify them. Extinction and evolution are a normal part of the life cycle on Earth. Of all

Contrast Conserving biodiversity should be a major concern to all humanity on this planet. Biodiversity is what sets living organisms apart from each other‚ mainly the reason why we have so many species roaming our world. Beyond the immediate concern with the loss of a particular population‚ species‚ or ecosystem‚ a focus on long-term recovery and biological revival is also essential. Humans need to play conservation offense as well as defense to keep biodiversity of species alive. There are

Climate Change and Biodiversity How Global Warming Affects the Life on Earth Climate change is the changing of patterns in climate‚ and the most obvious changes are usually the average temperature and the average precipitation. Climate change will also affect the timing of seasons‚ as well as causing extreme events to happen‚ for example‚ drought‚ fire‚ hurricane‚ etc. Since climate is defined as a certain region’s long term atmospheric conditions‚ the change of climate will have a great impact

Biodiversity study guide 1. Briefly describe how our species started to appreciate the biodiversity of the planet (in a geographical and historical context)? Through the concept of evolution‚ ecology‚ population‚ community and the environment. Species through different periods evolve physiologically and adapting to new environments. Animals who can’t live or survive in certain regions either migrate or die. Common ancestors often link to present day organisms showing biologically and different

Ecosystem is a system formed by the interaction of all living organisms with each other and with the physical elements of the environment. The vulnerability of an ecosystem can be determined through the examination of its location‚ biodiversity‚ extent and linkages. The vulnerability of the ecosystem is closely linked with the effectiveness of the functioning and the diversity of the ecosystem. The resilience of an ecosystem is also important when looking at the survival of ecosystems. Resilience

It has a right to exist‚ whether or not it is known to be useful to humans. All life is sacred and must be protected. Humans are no more important than other species. They all have a good of their own and both deserve to be valued.Thus everything has an equal right to exist simply because it already
