Environmental Biotechnology Flashcards
effects of global warming
floods, droughts, smog
recipients of the 2007 Nobel Peace Prize (2) and why?
Intergovernmental Panel on Climate Change (IPCC) and Al Gore
for their efforts in spreading knowledge about climate change and laying out solutions to it
What is the Greenhouse Effect
Greenhouse gases preventing the release of heat from the earth
projected temperature increase range for this century?
1.5°C to 9°C
What is the average rate of sea level rise?
1.8 ± 0.3 mm/year
how has global warming affected hurricanes
number of hurricanes hasnt changed but intensity has increased (more category 4 and 5) due to increasing sea surface temperatures which give them more energy
effects of climate change on wildlife
Polar bears need ice
Sea turtles will become extinct when their breeding beaches are submerged
Rare species could become extinct due to changes in rainfall
which of Earth’s atmospheric gases are greenhouse (5) and non-greenhouse (2)
greenhouse: Water (H₂O), Carbon Dioxide (CO₂), Methane (CH4), CFCs, Nitrous Oxide (N₂O)
non greenhouse: Nitrogen (N₂), Oxygen (O₂)
what is the runaway greenhouse effect
a planet’s atmosphere traps so much heat that it leads to uncontrollable and self-reinforcing warming. the warming leads to more greenhouse gases being released, causing a feedback loop.
What is the runaway greenhouse effect associated with?
Venus
what is Environmental biotechnology (2)
Environmental biotechnology is when biotechnology is applied to and used to study the natural environment
the development, use and regulation of biological systems for remediation of contaminated environments (land, air, water), and for environment-friendly processes (green manufacturing technologies and sustainable development)
methods for mitigating global warming (8)
Conservation: Reduce energy needs, Recycling
Alternate energy sources: Nuclear, Wind, Geothermal, Hydroelectric, Solar, fusion(?)
What is the definition of waste according to the text?
Produk sisa atau produk sampingan yang tidak dikehendaki
What are the types of waste mentioned?
- Sampah Organik/Basah * Sampah Anorganik/Kering * Sampah Bahan Berbahaya dan Beracun (B3)
What percentage of urban waste is organic waste?
71.85%
