Why should we protect them?
Endangered and threatened species of wildlife and plants “are of esthetic, ecological, educational, historical, recreational, and scientific value to the Nation and its people.”(Endangered Species Act of 1973) Protect other species is to protect human himself. The earth can recover anyhow, but human can not handle the collapse of the ecological system.(/article/89800/)

Dolphin Hunting in Japan
The whale and dolphin hunting season in Japan usually begins on September 1 each year. (In 2009, the hunting began on September 9. Although activists tend to believe that it was because of the publicity generated by the film The Cove, it has been reported that the delay was due to the weather and rough seas.) According to campaigners, out of the 100 dolphins captured on September 9, some were taken to be sold to marine museums and the rest were released, while 50 pilot whales were killed and sold for meat on the same day. On March 23, 2010 the Japanese government stated "The dolphin hunting is a part of traditional fishery of this country and it has been lawfully carried out.
3. Reduce the Threat of Invasive Species compete with native species for resources and habitat. prey on native species Another way to reduce the threat of invasive species is to incorporate native plants in your garden and to welcome native animals into your yard.

6. Place Decals on Windows to Deter Bird Collisions
By protecting habitat, entire communities of animals can be protected together and when communities are kept intact, less conservation intervention is required to ensure species survival. Parks, reserves, and other protected lands are too often the only habitats left untouched by habitat destruction.

What’s Nature Facing?
In the past five centuries, about 900 kinds of plants and animals disappeared from the earth. The current rate of extinction is much higher than the natural or background rate of the past. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as Endangered (EN) worldwide. The figures for 1998 were, respectively, 1102 and 1197.[1]
4. Recycle and Reduce Energy and Goods Consumption recycling and reusing take a little of the burden off our natural resources (and our pocketbooks) reduce your carbon footprint by first calculating your current carbon footprint and then reduce the amount of carbon you consume.

1. Protect Wildlife Habitat the greatest threat deforestation, farming, over-grazing irreversible changes: soil compaction, erosion, desertification, alteration of local climatic conditions. alter or even eliminate wildlife habitat

2. Join a Conservation Organization
Different objectives: protect a small plot of land protect whales establish good environmental policies in local government…… Organizations： The Nature Conservancy World Wildlife Fund Natural Resources Defense Council International Crane Foundation…… By joining in, you can support well-organized, ongoing efforts to protect species and habitats. And if you want to participate in conservation field work, you can often get involved in specific programs within many conservation organizations that rely to a great extent on help from volunteers.
5. Minimize use of Herbicides and Pesticides hazardous pollutants a long time to degrade build up in the soils or throughout the food chain amphibians are particularly vulnerable
A scene in The Cove
Dolphin Hunting in Japan
The Cove is a 2009 documentary film that analyzes and questions dolphin hunting practices in Japan. It was awarded the Academy Award for Best Documentary Feature in 2010. The film is a call to action to halt mass dolphin kills, change Japanese fishing practices, and to inform and educate the public about the risks, and increasing hazard, of mercury poisoning from dolphin meat. The film is told from an ocean conservationist's point of view. The film highlights the fact that the number of dolphins killed in the Taiji dolphin drive hunting is several times greater than the number of whales killed in the Antarctic, and claims that 23,000 dolphins and porpoises are killed in Japan every year by the country's whaling industry. The migrating dolphins are herded into a cove where they are netted and killed by means of spears and knives over the side of small fishing boats. The film argues that dolphin hunting as practiced in Japan is unnecessary and cruel.
