Ancient American Dogs Wiped Out by Expanding European Civilization

The ancient dogs of America that had arrived in the region along with the human beings around 10,000 years ago had been alter on wiped out from the region & existence by the expanding European Civilization. This fact was laid down by an all-new study. In addition to the few genes that are found in the modern-day dogs, the only remaining trace of the original dogs of America back then in the canines of the current era are found through the common form of canine tumor.

The history of the evolution of dogs in the world has always been complicated. This is because the dogs of today are more like a complex mixture of genes belonging from several breeds. A new study had observed over 71 archeological dogs by collecting & studying the respective genes from the remains found in Siberia & North America. These genes have been compared with the dog genes of the modern-day dogs.

A new study has however, tried to dispel the previous results with respect to the origin of dogs in the region of America. This theory posted that the dogs in America evolved from the domesticated wolves. The research & its findings have revealed that there is no particular evidence of this fact. In the given study, the researchers obtained DNA samples from the remains of the dogs that had spanned time (over 1000 years) along with space including Siberia & North America. The research suggested that a particular origin from the Eurasia and more particularly belonging to Siberia were the first dogs to arrive in America more than 10,000 years ago. Later on, the dogs spread across the region wherein they lives & thrived for over 9000 years –remaining isolated from the surrounding world.

However, those dogs were not the ones that you would like to pet today. Instead, the contemporary breeds of dogs have been likely stemmed from the instances of dog species that were brought to the America & its regions more than 1,000 years ago as per a new study. These included the Arctic dogs that were brought in by the Thule people some thousand years ago. These arctic dogs were the ancestors to the modern-day species including Greenland dogs, malamutes, and huskies. These dogs were introduced into the European region somewhere around the 15th century. Similarly, the Siberian Huskies were brought to the American Arctic region somewhere during the Alaskan Gold Rush period.

Devastating Effects of the Colonization Over Dog’s Population

The introduction of the European dogs has been by far considered to have created the biggest impact. There have been suspected several reasons for the wiping out of the ancient American dogs from their existence. The European colonists viewed the native dogs as some kind of pests and thus, freely killed them. At the same time, some of the Spanish explorers would come across lack of food and they would turn to the native dogs as forms of food back then. All of these factors led to the extinction of the ancient native dogs in America.

Tips to Reduce Individual Carbon Footprints

The world we live in today is contributing massively to significant global warming. Owing to the immense adverse effects of global warming to our planet, it is high time that we consider taking effective steps towards reducing our sources of pollution & global warming. Though the government authorities of most of the countries take up preventive measures towards preventing pollution, it is the responsibility of each individual out there to reduce carbon footprints on a personal level.

If you are looking forward to contributing to reducing carbon footprints individually, then here are some steps that you can take up:

  • Consider Alternatives to Driving: Whenever possible, consider walking on your own or taking up some public means of conveyance for avoiding your individual carbon emissions completely. Public transportation and carpooling can drastically help in reducing carbon dioxide emissions by spreading them out across several riders effectively.

 

  • Insulate & Seal Your Home: Try reducing air leaks and drafts with insulation, caulk, and effective weather stripping. There are several countries offering specialized programs as well as incentives towards facilitating this. You can consider taking up professional help from the same.

 

  • Add Solar Panels: Solar panels might appear an expensive affair to many. However, it can turn out to be an effective one-time investment towards reducing your individual carbon footprints to a greater extent. You can try installing solar panels to the roof of your home. This can turn out to be immensely energy-efficient and can save the emission of excess amounts of carbon dioxide through other means of energy production.

 

  • Cut Meat Consumption: For those who might not be aware of the fact that it takes a lot of resources including water and energy in raising a meat industry, it is high time that you consider going vegetarian or vegan. The beef and dairy industry contributes a lot to deforestation and wastage of the earth’s natural resources like forests and water.

 

  • Reuse & Recycle: This turns out to be the golden rule of reducing your carbon footprints on this planet. As per a recent study, it has been revealed that around 20 percent of the overall greenhouse gas emissions come from the provision of goods. This implies the extraction & production of resources, transportation, and the eventual disposal of goods which would also include product packaging, passenger vehicles, and building components. When you buy used products & try recycling or reselling the items that you might no longer use, you are dramatically reducing your overall carbon footprints.

 

  • Support Green & Clean Energy Sources: Whenever it is possible for you, try advocating for cleaner & greener alternatives to fossil fuels. These alternatives could include solar energy, wind energy, hydroelectric energy, geothermal, organic energy, and so more.

 

  • Be Smart Electric-Savvy: If you happen to be an electric appliance-enthusiast, then it is vital that you should act like a smart user. There are several energy efficient options when it comes to buying electrical appliances like refrigerators, air conditioners, and so more

Endangered Animal Species That Would Be Declared Extinct By The Year 2020

 

 

Introduction

To fit the changing ecological system, new species evolve, and old species die. Of all the organisms that lived on Earth, more than 90 percent are now extinct. However, the rate of extinction is not constant. In the ecological blink of the eye, more than 90 percent of the species have vanished in the last 500 million years. Because of human activities, the animal species are undergoing a biological extinction (Arnold, 2018). The extinction levels are found to be 1000 times higher than they are expected. Research shows that 1 out of 200 species of insects, plants, mammals, and birds disappear in every 24 hours from the Earth. Animals that face extinction due to mass extinction are listed in the list of International Union for Conservation (IUCN). Some of the animal species are listed below:

  1. Pika

A small mammal Ili pika that is only 7 to 8 inches in length is the native of Tianshan mountain range of China’s remote Xinjiang region. It lives on the slopes of bare rocks and feeds on grass. It is a rare animal as less than 1000 of this species is left. They were discovered in 1983; however, after that, they have decreased by 70 percent. The reason for this is the climate change that has adversely affected the habitat of this mammal. Due to the increase in temperature, they have moved to the top of the mountains. Furthermore, the air pollution has also contributed to their near extinction status. (Donovan,2018).

  1. Giant Otter

The giant otter is only found in South America. It is considered the largest otter in the world as some of them are 6 feet long. Historically, hunting of giant otters was for their pelts. That resulted in their massive reduction. Although this animal is not hunted today, they are still endangered as most of their aquatic habitats are destroyed that results in the decrease in their food, i.e., fish population. The gold- mining in the region is also a significant threat to them as it leads to mercury poisoning.

  1. Amur Leopard

One of the most endangered wild cats in the world is Amur Leopard. It has long and dense hair with a thick yellow coat. It can weigh up to 120 pounds and can jump more than 19 feet. The running speed of this animal is up to 37 miles per hours. This creature is now only found in Amur River basin of Eastern Russia, and according to WWF, only 60 wild Amur Leopards are left (Cherian,2017).

  1. Darwin’s Fox

This animal was found in 1834 by famous scientist Charles Darwin and has also was named after him. This carnivorous creature is found in two places in Chile, i.e., the island of Chiloe and the Nahuelbuta National Park. It is dark in color and has short legs. This creature becomes active at dawn and twilight. They are considered as “Umbrella Species” which means that protecting this creature and its habitat will help in protecting the whole ecosystem. Hunting, loss of habitat and the non-native species such as domestic dogs are the main threats to this creature as per IUCN (Berke, 2018).

WWF has asked the governments and people to do their part in minimizing the pollution. The countries can bring a change by reducing their carbon footprints, using the online carbon footprint calculators available. People should also avoid buying anything that is made from materials which are a reason for threats to the endangered species (Carrington, 2018).

 

Help our planet: steps for protecting the environment

Why should we care about our environment? On the last post, we talked about the factors that are ending with our species. We are responsible for the majority of the problems that are affecting our world today and many of us don’t know what to do to make things better. Today we’ll mention some of the actions you can take easily to making our planet a healthy place to live. Believe this: Your actions can make a huge difference. Start today!

  1. Use reusable bags. A simple thing, right? You can make a huge difference just by using reusable bags and avoiding the plastic ones. As you may know, plastic is one of the most contaminants in our world and we should stop considerably its use. Going green and help our earth is easier than you think, with baby steps you can be an example for others and show how simple is taking care of our world.
  2. Recycle as much as you can. If you recycle only one can of coke you’re saving enough energy to watch your tv for three hours.
  3. Reuse plastic. As we mentioned in the first point, plastic is very toxic and less you use and less you throw away, the better. Drink water from a reusable bottle and avoid buying frequently.
  4. Reduce meat. It’s ok if you don’t want to be vegetarian, is a personal way of living that everybody should be free to choose. If aren’t willing to give up animal products, just try to reduce the quantity of them. Not only you’ll be contributing to your health by increasing the intake of vegetables, but also, you’ll be reducing your carbon footprint. Industry produces more greenhouse gas emissions than vehicular transport.
  5. Conserve water: is impossible exist without it and if we don’t conserve it maybe it won’t last forever. Preserving water is caring for our earth and our future, don’t waste it! Use it responsibly and stay conscious of its relevance.
  6. Contaminate: a Large amount of waste is in the world and have been produced by us. Why we have the streets full of trash? Why we create products that are so difficult to degrade? Companies are expelling incredible amounts of carbon dioxide per day and we can help by recycling and use products that are biodegradable.
  7. Energy: Like water, we waste so much energy daily that unfortunately, is one of the main enemies of our earth. Humans use energy from fossil fuels like natural gas, oil, etc. this generates a large amount of carbon oxide and nitrogen oxide that is one of the principals responsible for climate change. Save energy as much as you can, turn off the light that you aren’t using and all the devices you don’t need. You can make the difference.
  8. Be kind: Yes, is very important. If you practice kindness every day you’re making the difference and contributing to make this world a better place to live. There are so many things we can do each day to stop the deterioration of our planet. We mentioned the most basic ones, start with those and you’ll be helping enormously.
