3 billion birds have disappeared from America and Canada in 50 years. The number of birds in North America has decreased by 3 billion in the last 50 years. There were 10.1 billion birds in the US and Canada 5 decades ago, which has now reduced to 7.2 billion. This is revealed in Cornell University’s research. According to research published in Science Journal, these need to be taken care of, lest it is delayed.
The population of birds known by the weather radar
Researchers have collected data on bird numbers using weather radars. Which gives information about the herd of birds. Computer models were also used to explain the trend of 529 bird species of North America in 13 surveys conducted on birds since 1970. Researchers say not all but three-fourth of species of birds have been affected
Researcher Rubega says that the 3 billion birds that used to eat insects that damage crops and spread diseases such as encephalitis have migrated from the world. It is a matter of thinking. The worst is that of the easily recognized bird sparrow. However, the number of all sparrows is not decreasing. As the bluebird population is increasing.
According to the researchers, the biggest reason for the decrease in the population of birds is their habitat loss. Cats are a major cause of bird deaths in the US and Canada, a 2015 research says. Which kills 26 million sparrows every year. In addition, 62.4 million birds die after hitting windows and 2.14 million birds collide with cars.
Researchers say cats have to be kept indoors to increase the number of birds. The windows have to be used in such a way that there is no problem for the birds. Along with this, the use of chemicals in farming has to be reduced.
Tateh, born in Refugee Camp, home to refugees made from bottles, Dawa; Able to withstand the weather
Tateh Lahbib of Algeria is building houses with plastic bottles. Born in Refugee Camp, Algeria, Tateh says that when I lived here, I had to face strong heat, rain, and storm. Many times the roof was blown away due to strong storm. So, I want to do something that brings relief to the people living here. So the bottles were used as bricks and zinc sheets were applied to the roof. Tateh is now building homes for many refugees.
The white color will protect against ultraviolet rays
Tateh has recently been awarded a scholarship by the United Nations Refugee Agency to study renewable energy. He has chosen the place where he was born to study. Tatel was born in Alharia’s Sahrawi Refugee Camp when thousands of people had to take refuge in Western Sahara due to a dispute.
According to Tateh, these are special kind of houses, they are able to withstand the outbreak of weather to a great extent. Plastic bottles can neutralize water, whereas the design of bottles is capable of fighting sand storms to a great extent. The bottles are sanded before making the house. Then connect them with cement and limestone, one by one.
Zinc sheets are used to make the roof which keeps it tied to the house and does not blow when a strong thunderstorm comes. The house is painted with white paint, which reduces the effect of ultraviolet rays by 90 percent. The United Nations Refugee Agency has also shared a video of it and the agency says Taatej is no ordinary engineer.
The video is being shared on social media. Users are telling this to be the best innovation. People say that people are getting homes in such use of plastic, there is protection from the weather and the environment can be saved.
