Hi it is time for speeches for year five and six I am aiming to get in the finals. Here is my draft speech
Deforestation
Intro
Forests are
home to most of the plants and species on the earth. As the forest are
destroyed, many species die out – an estimated 50,000 species a year. 80% of NZ
used to be covered by forest. 12 to 15 hectares
of forest are lost every year to deforestation. That’s the equivalent to 3
soccer fields every minute. I’ll give you an example hmm, how about the Amazon
Rainforest, more than forty thousand varieties of bird species and over 2
thousand fish species!... But 2,700 million acres are burnt each year L
1/ Causes biodiversity to decline
2/ Release of greenhouse gasses emissions
3/ Disrupted water cycles
4/ Increased soil erosion
Body
Deforestation is the removal of tree’s transforming a forest
into cleared land through logging or burning either to use the wood or use the
area for alternative uses.
Biodiversity
Cutting down forests upsets biodiversity. Biodiversity, is the
term used to describe the variety of life found on Earth and the connections
between all these species and the environments they live in. Biodiversity is important to sustaining
life on earth because it prevents any one species from throwing the balance of
nature out of order. For example, snakes are not a welcome presence in our
lives. We fear them and kill them because of it. One of the many things that
snakes feed on is rats and if we were to kill of all the snakes, we would end
up having a terrible rat problem. Therefore humans should to everything in
their power to conserve the natural variation of snakes to ensure it doesn’t
get an unnatural rat problem. Destroying forests will upset this delicate
balance.
Greenhouse gasses
Greenhouse gasses are gases in our atmosphere that warm up
our world. If we didn’t have these gases our world would be too cold to live in
but on the other hand if these gases become stronger it could make the earth
even warmer than usual, this may cause problems to human’s plants and animals.
Cutting down forests causes 15% of greenhouse gas releases into the atmosphere
which may increase the temperature of our world.
Disrupted water
cycles – Forests transport
large quantities of water into the atmosphere this fills up the cloud which
causes rain which maintains the forests – this is nature’s way of keeping the
ecosystem running perfectly. BUT when forests are cut down there is less rain
which causes the land to become very dry and that means is will be upsetting
the ecosystem.
Conclusion
How can we stop (shrug) It’s actually the people that cut
down the trees but, reduce your paper, reduce your oil Well, as things go on we
are hardly noticing what is going on at every hour… minute… Second… Moment…
