The effects of deforestation on our planet (Explainnation)

  The effects of deforestation on our planet 

 

In 100 Years, there will be no Rainforest  Now, there is less than 10% left. Deforestation is when forests are converted for other purposes by cutting down the trees to clear the land for other use. With 7 billion people on the planet, we need more land to build cities, raise livestock and grow food. The loss of trees and other plant growth can cause climate change, the start of a desert, oil, fewer crops, flooding, increased greenhouse gases in the atmosphere.

People use wood for fuel also the soil for fossil fuels. There are 5 major rainforests that are getting cut down: Russia, Brazil, Canada, USA and more such as China.  Forests still cover about 30 percent of the world’s land area, but they are disappearing at an alarming rate.

Between 1990 and 2016, the world lost 502,000 miles and 1.3 million kilometres of forest, according to Google, an area larger than South Africa. Since humans started cutting down forests, 46 percent of trees have been logged, according to a Google site that Osheya Wilkinson read. About 17 percent of the Amazonian rainforest has been destroyed over the past 50 years, and losses recently have been on the rise.

That's because, starting in the late 1960s, Brazil began cutting down and burning forest at an alarming rate. An average of 137 species of life forms are driven into extinction every day in the world's tropical rainforests.  The forces of destruction such as logging, cattle ranching have all contributed to the loss of millions of acres of tropical rain An average of 137 species of life forms are driven into extinction every day in the world's tropical rainforests. 

One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant species due to their loss of habitat. 70% of land animals and plant species live in forests. The trees of the rainforest that provide shelter, some species also provide the canopy that regulates the temperature. In conclusion this very bad for the environment, so we need to stop, deforestation # STOP DEFORESTATION.

Why the moa became extinct (Explanation)

 Why the moa became extinct.

Maaori killed them for their flesh  which was eaten. Their feathers were used for clothes and their bones were used for hooks and pendants. Then, about 600 years ago, they  quickly went extinct. Their die off coincided with the arrival of the first humans on the islands in the late 13th century, and scientists have long wondered what role hunting by Homo sapiens..

Moa was a large, flightless bird that lived in New Zealand until 1400 years AD. There were around 11 species of moa, some of which appeared on the planet 2.4 million years ago. Moa had lived in the forests, scrublands, grasslands or upland habitats.  Moa were

able to reach 12 feet in height and up to 550 pounds of weight. It was one of the tallest birds that ever lived on the planet. Females were taller and heavier than males.  Haast's eagle and humans were the only enemies of moa.

The preserved stomach contents of the Giant Moa show that they snipped twigs off plants such as the daisy–bush, daisy bush , and ate them. They also ate berries and leaves. Like many birds, they had to swallow stones to grind up the food in the gizzard.   According to Maori tradition, moas were swift runners that defended themselves by kicking when cornered. Early Polynesian peoples hunted moas for food and made spear points, hooks, and ornaments from their bones and water carriers from their eggs. Although the larger moas probably became extinct by the end of the 17th century, a few smaller species may have survived into the 19th.   By Osheya
