Introduction
Animals go extinct due to habitat loss, being hunted a lot, and diseases. Animals that are about to go extinct (because they are endangered) matter for us humans because it has a large myriad (a big number) of implications with our food, water, environment and even health. Animals are also important because we depend on healthy ecosystems to purify our environment. Without healthy forests, grasslands, rivers, oceans and other ecosystems, we will not have clean air, water, or land.
Who is responsible for helping aquatic animals?
According to the National Marine Fisheries Service, the NOAA Fisheries and the U.S. Fish and Wildlife Service share responsibility for implementing the Endangered Species Act, which is the primary way the federal government protects species in danger of extinction. The purpose of the act is to conserve endangered and threatened species and their ecosystems. NOAA Fisheries is responsible for endangered and threatened marine life from all types of species, from whales and seals to sharks, salmon, and corals. The U.S. Fish and Wildlife Service is responsible for species on land and in freshwater, but also has responsibility over several marine species like sea otters, manatees, and polar bears. The U.S. Fish and Wildlife Service and NOAA Fisheries also share laws and decisions over several other species such as sea turtles and Atlantic salmon.

How can individuals contribute to conservation efforts in their daily lives?
According to The Endangered Species Coalition, a coalition of 400+ organizations and hundreds of thousands of activists fighting to protect endangered animals, there are ten easy things we can do to save endangered animals.
How are animals helped to not go extinct by professionals?
According to the National Wildlife Federation, they defend, strengthen, fund, and ensure effective implementation of the Endangered Species Act and other core wildlife protection laws. The defending and strengthening helps the Endangered Species Act, which provides an essential legal safety net to prevent the loss of plant and animal species to extinction. Some other work they do is protecting, restoring, and connecting the habitats on which endangered species and other wildlife depend for their survival, and encouraging wildlife-friendly land management practices. Lastly they reduce wildlife that can lead to their endangerment and extinction, such as loss of habitat, contamination of water and spread of invasive species.
Conclusion
In conclusion there are many ways to stop animal extinction. Some of the ways professionals use are protecting, restoring, and connecting the habitats on which endangered species and other wildlife depend for their survival, and encouraging wildlife-friendly land management practices. Lastly they reduce wildlife that can lead to their endangerment and extinction, such as loss of habitat, contamination of water and spread of invasive species.
