7523QCA Emerging Design Futures-Week 10

Through this week, I researched plant’s benefits for human, ecosystems and animals.

Trees can produce oxygen and purify the air that benefits human health.A typical tree can absorb around 21 kilograms of carbon dioxide per year. For every 44 grams of carbon dioxide absorbed by a tree, 32 grams of oxygen can be emitted.

Forests are one of the key pillars for maintaining global, national and local biodiversity. When trees are young, they offer habitation and food to amazing communities of birds, insects, lichen and fungi.When trees are ancient, their trunks also provide the hollow cover needed by species such as bats, woodboring beetles, tawny owls and woodpeckers.

Afforestation can greatly improve the ecological environment and reduce the loss of flood disasters and sandstorm. The canopy has the function of rainwater intercepting. It can reduce the impact of rainwater on the ground and conserve water and soil.

I also researched the facts about deforestation in Australia. Australia has lost 27% of the rainforest, 19% of open forest, 11% of woodland forest and 28% of mallee forest since 1750.

I put all of my findings into PowerPoint and I am ready to present them next week.
