Dear Groups 1, 2 and 3 students, you will focus on global warming while Groups 4, 5 and 6 students will focus on deforestation.

Please watch the videos below and answer the following questions:

1) What are the effects of global warming/deforestation?
2) How does global warming/deforestation impact humans and other living things?
3) What should humans do to reduce the negative impact on the environment?

You are strongly encouraged to put up extra information you know about global warming and deforestation for your peers.
Hope to read your replies soon:)

Regards,
Ms Seow

Q:
1) What are the effects of deforestation? How does deforestation impact humans and other living things?
--------------------------------------------------------
A:
Deforestation is 24% part of global greenhouse gas emissions. Deforestation impacts the amount of greenhouse gases in the atmosphere in these 2 ways:
1) When the trees get cut down, the amount of carbon dioxide stored in them are released into the atmosphere.
2) Trees play a critical role in absorbing the greenhouse gases that fuel global warming.
Fewer forests means larger amounts of greenhouse gases enter the atmosphere and when it rains, there would be lesser trees absorbing water from the rain and floods would occur more frequently. Hence, it increases the speed of global warming.
========================================================
Q:
2) What should humans do to reduce the negative impact on the environment?
---------------------------------------------------------
A:
Humans should selectively choose trees to cut rather than cutting down every single tree while the other trees try to help maintain some of the ecosystem functions. Humans should also selectively choose regions so that we could protect endangered species' habitats. Also, we should the 3 R's. Use lesser items made out of trees, use reusable items and finally dispose waste properly by making sure recyclable items go into the correct bin so that they can be remade into something new.

Deforestation can cause global warming as cutting trees down release carbon dioxide into the atmosphere,causing the sun ray to be reflected back to earth,if there are less trees there would not be enough oxygen and animals will lose their habitat.We need recycle,the tree cutters have to select what to cut and don't cut small trees.

Q1:
What are the effects of global warming/deforestation?
-------------------------------------------
A1:
When the trees get cut down, the amount of carbon dioxide stored in them are released into the atmosphere. Trees also play a critical role in absorbing the greenhouse gases that fuel global warming. Hence, that means fewer forests means larger amounts of greenhouse gases enter the atmosphere and when it rains, there would be lesser trees absorbing water from the rain and floods would occur more frequently. Hence, it increases the speed of global warming. If there are lesser trees, here would be lesser oxygen and animals would lose their habitat.

Q2:
How does global warming/deforestation impact humans and other living things?
-------------------------------------------
A2:
When it rains, there would be lesser trees absorbing water from the rain and floods would occur more frequently. Hence, that means that more houses would be destroyed due to floods and animals' habitats would be destroyed. Humans and animals would have no places to stay at after a flood.

Q3:
What should humans do to reduce the negative impact on the environment?

-------------------------------------------
A3:
Humans should selectively choose trees to cut rather than cutting down every single tree while the other trees try to help maintain some of the ecosystem functions. We should also use the 3 R's which are Reduce, Reuse and Recycle. Use reusable items and finally dispose waste properly by making sure recyclable items go into the correct bin so that they can be remade into something new.
