you asked 2 questions
Question one
What do you think about global warming?.
I think Global warming is true
This week, one of NASA's top scientists concluded that the Arctic Ocean could be nearly ice-free within five years, much faster than all previous predictions.
when the north pole is gone , you may have polar bears soon in America ,looking for a home ,
Calculations do not include the accumulative ,speeding up ,factor with time. the increase in water temperature will get faster all the time as well as the melting,
when the ice is all gone the deeper cold Ocean currents will stop ,and the drag has gone with it ,also changing the higher warm currents,And only the moon will keep things moving
This will affect coastal climates ,world wide ,almost instantly. All aquatic flora and fauna will be affected,many dying off and others becoming invasive,
Right now In Chiapas ,and Tabasco in Mexico .more then a million people became homeless overnight with water coming up to their roofs ,because of rains from super evaporation from the forests,this had never happened before. Millions of animals died.
In India 3000 people died because of super storms .
.A few years ago in Europe 3500 people,died during a heat wave ,many of them in France .
Right now the average death toll annually is 150.000 due to Global warming
. these figures are already out of date and are expected to double soon.
In Northern China millions of people are running for their lives because regular dust storms so far have buried 900 villages under the sand and the whole of northern China is turning into a dessert.
The Sahara is growing by 7 kilometers a year all around the edges ,like a slow burning fire shriveling up their neighbors In the Kalahari huge rivers have dried up and thousand of species are gone due to their habitats disappearing .
The biggest changes are invisible at micro biotic levels species are becoming extinct ,others are multiplying ,
This affects the insect populations that follow ,and changes in that ,affect all that follows in the food chains ,
All life is interrelated of both flora and fauna, And since we are on the top of the food chain ,
we are always the last to know.
So Global warming has its toll there are incidents all over the world ,

Question two
5 reasons why Humans are contributing to the natural cycle and speeding it up
1) POLLUTION
AIR pollution and the green house effect
Soil pollution,which causes us to exploit more (un contaminated ) land
Water pollution which cause us to use more (un contaminated) water
2) OVER POPULATION
70 million more people each year ,drink ,destroy and eat
putting pressure on natural resources ,such as water and soil,
and expanding settlement which diminishes the Natural world.
3) DESERTIFICATION
because of Deforestation, for agriculture
4)Overgrazing.
5)Over pumping Carbon Aquifers and wasteful irrigation,which deplete ground water supplies ,and the trees die ,and when the irrigation stops ,everything dies
