What are the six killer diseases of a child?

These six are the target diseases of WHO’s Expanded Programme on Immuni- zation (EPI), and of UNICEF’s Univer- sal Childhood Immunization (UCI); measles, poliomyelitis, diphtheria, pertussis (whooping cough), tetanus and tuberculosis.

Can we reverse extinction?

Cloning in a nutshell We’re turning back time – Scientists are on the verge of being able to reverse extinction. They are taking DNA from fossils and museum specimens, and using some fancy, high-tech science to make copies of various extinct animals.

Why does extinction happen?

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).

Can diseases cause extinction?

Infectious disease, especially virulent infectious disease, is commonly regarded as a cause of fluctuation or decline in biological populations. However, it is not generally considered as a primary factor in causing the actual endangerment or extinction of species.

Can we prevent extinction explain?

Protect wildlife habitat. Perhaps the greatest threat that faces many species is the widespread destruction of habitat. Scientists tell us the best way to protect endangered species is to protect the special places where they live. Wildlife must have places to find food, shelter and raise their young.

What are the causes of extinction?

There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption.

Which disease has no cure?

cancer. dementia, including Alzheimer’s disease. advanced lung, heart, kidney and liver disease. stroke and other neurological diseases, including motor neurone disease and multiple sclerosis.

What are benefits of saving endangered species of animals and plants?

The benefits of conserving endangered species Clean air and water improves our quality of life, and fertile land for agriculture ensures that we can produce enough food for consumption. A balanced ecosystem also provides us with plants that have medicinal properties.

Why shouldn’t we save endangered species?

Experts have a simple answer: if we don’t invest money into saving endangered species now, we will have to invest far more in the future. For example, if there are no bees, food will become way more expensive, and if vultures go extinct, cases of rabies and an increase in medical expenses are inevitable.

Why is it important to prevent the extinction of plant and animal species?

Healthy ecosystems depend on plant and animal species as their foundations. When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment.

Why is it important to save plant species?

Plants prevent soil erosion and desertification. Plants provide the raw materials for food, clothing, medicines, construction and many other products that sustain our lives. Plants enhance our quality of life – they add variety and beauty to our surroundings.

What ended the Black Plague?

1346 – 1353

2. Create a backyard wildlife habitat.
3. Establish a pollinator garden with native vegetation in your yard.
4. Minimize use of herbicides and pesticides.

How can we save the endangered species of plants and animals?

Conserving Wildlife: 20 Extraordinary Things You Can Do to Save Endangered Species

When was last pandemic in history?

Are humans the main cause of animal extinction?

Human activity puts 1 million species of plants and animals at risk of extinction, a startling report from the United Nations showed recently. It’s a sobering warning — but if we rethink conservation, such destruction doesn’t have to be our future.

Was there a pandemic in 1620?

Plague repeatedly struck the cities of North Africa. Algiers lost 000 to it in 1620–21, and again in 1654–57, 1665, 1691, and 1740–42. Plague remained a major event in Ottoman society until the second quarter of the 19th century.

What was last pandemic?

The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919.

How often does a pandemic occur?

The definition from the U.S. Centers for Disease Control and Prevention is nearly the same: “A pandemic is a global outbreak of disease. Pandemics happen when a new virus emerges to infect people and can spread between people sustainably.” The Facebook post suggests that pandemics only occur every 100 years.

How long did swine flu last?

How does animal extinction affect humans?

Scientists have also discovered links between the incidence of West Nile virus and hantavirus and local reductions in biodiversity. Animal extinctions may also rob humans of valuable medical advancements. Many different species have unique bodily processes that can offer insight into curing human disease.

How can we stop mass extinction?

3 ways to prevent mass extinction now

1. Reduce the burning of fossil fuels: This is underlying the obvious and cannot be stressed enough.
2. Reconnect with nature and protect the Earth’s landmasses and oceans: The latter point needs to be undertaken on a war footing.

Do diseases go extinct?

For a disease to be eradicable it needs to be a disease you can “catch” from other humans or animals, that is it has to be infectious. Non-infectious diseases, such as heart disease or cancer, cannot be eradicated. Without an effective treatment against a disease there is no possibility of eradicating it.

What is the deadliest disease in human history?

The 2014-2016 Ebola outbreak in West Africa began in a rural setting of southeastern Guinea, spread to urban areas and across borders within weeks, and became a global epidemic within months.

How do new diseases cause extinction?

“If you push a population down to an unsustainable number then it will collapse. In addition, if a substantial number of reproducing individuals became infected and ill, even if they survived the infection, their reproduction rate may be lowered and lead to a population crash.”
