|A Pair of Great Tits|
Over the past century, several types of animals, including turtles, tits, frogs or deers are becoming increasingly smaller.
The decrease of Arctic glaciers in recent years has led to considerable smaller polar bears. Because their environment is shrinking they must adapt and become smaller so they will survive in the future but the scientists are not sure if the polar bears can keep up with the accelerated pollution and they might face extinction.
Reduction of food reserves will affect especially the animals that are at the top of the food chain, including people who in the future will be increasingly smaller, will have fewer children and more vulnerable to disease.
In the last century, global average temperature has increased by almost one degree (Celsius), but after increasing industrialization scientists believe that around year 2100 the average temperature will be 7 degrees higher than today and this mean an mass extinction of animals and plants and possible humans.
A separate study conducted over 1700 species of plants and animals, proved that 80% of them moved their living area with 6.1 kilometers north every ten years and 87% bloom or begin the mating season two days earlier each decade.
Experimental studies have found that for every degree (Celsius) above the global average temperature, the plants lose about 17% of their size and the fish are becoming about 22% smaller.
As a retired nurseryman I can say that a one degree increase in temperature will make plants grow faster and larger not smaller and moving plants to a warmer greenhouse is done for that reason. I don't know why people bother printing this crap.
