Quiz time!

What is a habitat?: 

What is a habitat? A place where a particular animal travels in search of food. A place where an animal is sent to get rid of a bad habit. The location where a particular animal lives and its surroundings which includes environmental conditions such as air, water, temperature, the land The location where a particular person likes to shop.

What is the difference between an animal being threatened and endangered? : 

What is the difference between an animal being threatened and endangered? threatened animals are likely to die sooner than endangered animals. Threatened animals are likely to become endangered in the near future, endangered animals are likely to become extinct in the near future. Threatened animals are scared, endangered animals are angry Threatened animals are usually younger than endangered animals.

Why save endangered species? : 

Why save endangered species? It is very cool to have an endangered animal as a pet All animals and plants hold a certain musical, artistic, and athletic value. Every single living thing should never interact with its surroundings. If all species died there would be nothing left to eat. All animals and plants hold a certain medicinal, agricultural, ecological, commercial and recreational value. Every single living thing interacts with its surroundings.

Which is the world's most comprehensive inventory of the global conservation status of plant and animal species? : 

Which is the world's most comprehensive inventory of the global conservation status of plant and animal species? IUCN Red list IUCN Black list IUCN Blue list IUCN White list

¿Endangered species? : 

¿Endangered species? A species that is in danger of extinction throughout all or a significant portion of its range Because it is few in number threatened by changing environmental or predation parameters

!: 

! Alarming Facts !!!

Slide14: 

rate of species loss is 150 times higher than the natural background rate of extinction.

Slide15: 

we destroyed 30 % of the natural world between 1970 and 1995

Slide16: 

At the current rate of extinction the Earth will have lost 25% of its present number of species by 2050

Slide17: 

Roughly 50,000 species vanish every year

Slide18: 

many creatures will forever remain unknown to us, for they are disappearing before we get a chance even to learn about them.

Reasons for extinction: 

Reasons for extinction Natural loss Invasive species Human factors Habitat destruction Pollution Over-exploitation

Invasive species: 

Invasive species take over space and nutrients intensified by the destruction of habitats

Habitat Destruction: 

Habitat Destruction Deforestation Agriculture Housing development and human settlements Mining Water development

Pollution: 

Pollution Indirectly… chemicals ingested by animals low in the food chain these chemicals accumulated in food chain Until it reaches a dangerous level Causes reproductive problems and death

Pollution: 

Pollution directly… pollutants make water uninhabitable e.g. fertilizers and pesticides to reach waterways e.g. logging, grazing, agriculture, and housing development cause silting in waterways >>> fresh water mussels

Over-exploitation: 

Over-exploitation especially a threat for species that reproduce slowly Includes over fishing and hunting

Consequences of extinction: 

Consequences of extinction A danger of losing species as a biological entity destabilization of an ecosystem A danger of having endangerment of other species loss of irreplaceable genetic material and associated biochemical

1. A danger of losing species as a biological entity: 

1. A danger of losing species as a biological entity Irreversible Once a particilar species loses, it will never occur again

2. Destabilization of an ecosystem: 

2. Destabilization of an ecosystem One species go extinct and population will increase or decline in the secondary species unstable spiral ecosystem structure is changed markedly and irreversibly

3. A danger of facing endangerment of other species: 

3. A danger of facing endangerment of other species Relations between organisms are very complex and interdependent One type of species will affect the whole food chain

4. Loss of irreplaceable genetic material and associated biochemicals: 

4. Loss of irreplaceable genetic material and associated biochemicals Each species carries unique genetic material in its DNA and may produce unique chemicals according to these genetic instructions Examples: - a fernlike weed called sweet wormwood found in the valleys in Central China

¿Solutions?

International Efforts: 

International Efforts Wild Bird Conservation Act of 1998 Endangered Species Act Marine Mammal Protection Act

International efforts: 

International efforts World Wide Fund for Nature!

WWF’s recent attempts: 

WWF’s recent attempts 06 Feb 2007 South African abalone to come under international trade controls 02 Feb 2007Rare hyena spotted in Turkmenistan

International efforts: 

International efforts Green Peace!

Green Peace: 

Green Peace Go to www.greenpeace.org to save the whales!

Hong Kong ’s effort: 

Hong Kong ’s effort Chinese White Dolphins Marine Park ( around Sha Chau and Lung Kwu Chau ) deploys artificial reefs comprehensive conservation program for the Chinese White Dolphins conservation organization (WWF)

Constraints?: 

Constraints? still traversed by many types of vessels traffic has increased significantly

China’s Role: 

China’s Role conservation organization (WWF) 50 panda reserves

Individuals’ effort: 

Individuals’ effort Conserve Habitats national parks, nature reserves or wilderness areas When you visit a national park, make sure you obey the wildlife code encourage friends to keep patches of bush as wildlife habitats removing weeds and planting local native species in your place

Individuals’ effort: 

Individuals’ effort Make space for wildlife Plant a tree in the backyard Start composting in garden– eliminates need for chemical fertilizers Not to use harmful chemicals at home

Individual efforts: 

Individual efforts Join An Organization Join an organization in your area and start helping today!

Individual efforts: 

Individual efforts Voice out yourselves tell family members and friends about the endangered species and what they can do write articles to newspapers Ring up radio programs
