Without a strong plan to create terrestrial and marine protected areas important ecological habitats will continue to be lost. Stanford biologist Elizabeth Hadley provides expertise. Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers). Perhaps you feel bad for them, but that is the extent of how much you think about the effects of endangered species. Since 1964, when the IUCN established a red list of threatened species and began compiling data gathered worldwide, the list has become the preeminent global database of endangered life and an essential tool for conservation policy.

Among other impacts: diminished biological diversity, fewer ecotourism job opportunities and the loss of benefits science is only beginning to discover, according to a call to action issued by a team of international scientists, including Stanford biologist Rodolfo Dirzo. An estimated 8 million animal and plant species live on planet Earth. When a species disappears, biologists say that the species has become extinct. When species vanish, benefits to humanity can be lost, too from economic opportunities related to ecotourism to keeping in check populations of species that can spread infectious disease. Human activity is causing environmental degradation, which is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution.

Fossil research suggests evolutionary winners during most of the history of animal life included not only true behemoths of the sea, such as Jurassic fish as long as a bus, but also species who were giants of their kind. Scientists who study past extinction events can find clues about not only the evolution of life on Earth, but also about the effects of extreme changes in our planets atmosphere, and how life finds ways to rebound. This can cause a major problem for the other species living in that habitat of an ecosystem, shortage of food can arise with the time, which can lead to endangerment or extinction of other species. Fortunately, in 1973, the United States passed the Endangered Species Act (ESA) to protect those species on the brink of extinction. The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.

David Attenborough explores the extinction crisis and how it threatens food and water security, undermines our ability to control our climate, and puts us at greater risk ofpandemic diseases. When a species of an ecosystem gets extinct, it creates a space in the food chain causing instability and problems for the species dependent on them in terms of food.

The ESA aims to conserve and protect both endangered species and their habitats. While were doing that, we must also oppose the runaway development and other forces that threaten those same precious resources. Since 1906, the global average surface temperature has increased by more than 1.6 degrees Fahrenheit (0.9 degrees Celsius) even more in sensitive polar regions. When forests are logged or otherwise disrupted, it turns crucially important climate pollution-trapping carbon sinks into carbon emitters. Because the polar ice caps are shrinking, so are inhabitable areas for polar bears. Many scientists say a sixth mass extinction is now under way.
